Abstract:
An automotive quality paint coat is laminated to the exterior surface of a molded plastic car body member or panel. In one embodiment, the paint coat includes an exterior clear coat above a color coat. During processing, the clear coat and color coat are each coated on a temporary flexible casting sheet and dried. A high gloss surface is transferred to the clear coat from the casting sheet. The paint coat is then transferred from the casting sheet to a thin, semi-flexible thermoformable plastic backing sheet by dry paint transfer-laminating techniques. The resulting laminate is thermoformed into a complex three-dimensional shape of the car body member or panel. The preformed laminate is then bonded to an underlying plastic substrate material, by injection-cladding techniques, for example, to form the finished article. The paint coat has sufficient elongation to retain exterior automotive appearance and durability properties during thermoforming without deglossing. The backing sheet absorbs defects in the substrate material so the paint coat retains its appearance and durability properties during the injection-cladding step. The finished article comprises a high gloss, defect-free paint coat on the exterior of a molded plastic car body member or panel. Solution-form polyvinylidene fluoride/acrylic paint systems have remarkably high combined gloss and distinctiveness-of-image levels, together with durability properties required for exterior automotive use.
Abstract:
An article for applying a color shifting optically variable coating on a substrate formed from a polymeric web, a release coating on the web and an optically variable coating wherein the optically variable coating consists of a semi-opaque metal layer adjacent to the release layer, a transparent dielectric layer on the semi-opaque metal layer and a reflective metal layer on the dielectric layer. The article can be bonded to a substrate by means of hot stamping with the hot stamp adhesive layer being applied to the article or applied to the substrate.
Abstract:
An apparatus and method for applying adhesive on opposite edges of a longitudinal slit formed in a tubular body of resilient insulation material is provided. The apparatus includes a conveyor which moves the tubular body along a conveyor path. A feed assembly feeds a pair of tape strips along separate feed paths so that an adhesive applicator located adjacent to each feed path at an application point applies adhesive to a surface of the tape strip as it is fed along the feed path. A wedge-shaped plow is formed from a pair of flat plates which converge at an acute angle toward one another. The flat plates each have a leading edge which directs each tape strip from the feed paths along an exterior surface of one of the plates along lines parallel with the conveyor path. The lead edges of the plates engage the slit of the tubular body as the tubular body is moved along the conveyor path so that the edges of the slit are directed along the exterior surfaces of the plates with the edges of the slit contacting the tape strips. This causes the tape strips and adhesive to be applied to the opposite edges of the slit. A mandrel supports the tubular body as it is moved along the conveyor path into engagement with the plow so that the tubular body is held in a substantially tubular form.
Abstract:
A process for the preparation of a synthetic resin-shaped article having good antistatic properties is provided, which entails a) polymerizing a monomer mixture containing monomers (A), (B) and (C) to form a first copolymer; b) subsequently polymerizing monomers (D) and (E) in the presence of the first polymer to prepare a second copolymer; forming a film of the second copolymer on the molding surface of a casting mold; and supplying a starting material capable of forming a synthetic resin into the casting mold and polymerizing the starting material to form the substrate in the casting mold, thereby transferring the film of the previous step to the surface of the substrate from the molding surface of the casting mold.
Abstract:
A process for applying images by transfer printing disperse dyes onto furniture end pieces, especially end pieces for use in juvenile furniture. In one preferred embodiment the end piece board is first coated with a pigmented non-polyester base coat which is applied with rollers and conventionally cured. The board is then coated with a 100% polyester clear top coat which is also applied with rollers and UV cured. In a second preferred embodiment the board is coated with a pigmented polyester base coat which is either sprayed or roll coated and which may be either conventionally or UV cured. Finally a sublimation decal is transfer printed into the polyester coating using a press having heated platens and operated at about 400.degree. F. and at between 8-30 psi for between 20-40 seconds. For larger boards, a silicone pad may be attached to the upper platen of the heat press adjacent to the surface of the platen which contacts the transfer printing decal to improve image transfer for uneven presses. Also, for larger boards, the surface of the board opposite the side upon which the transfer print is applied is heated to a temperature about 10.degree. to 15.degree. F. greater than that side to substantially eliminate any warpage of the board during the transfer process.
Abstract:
A method for freely affixing a decorative pattern having a very excellent deep appearance on any stock or shaped body is provided, said method comprising coating said stock or shaped body with an active energy beam curable resin; placing a pattern-printed film so as to contact the resin with the pattern at a stage where the resin still remains in a liquid or sticky gelled state prior to curing, said pattern being printed with an ink having a greater affinity to said resin than said film, irradiating a beam toward the pattern-printed film-resin coated body to cure the resin concomitantly transferring the pattern on the film to the cured resin surface, removing the film and thereafter coating the transferred pattern bearing cured resin surface with a transparent or translucent resin.
Abstract:
A process is disclosed for decorating electron-beam-cured coatings on radiation-sensitive substrates such as paper and the like, with metallized decorative and other layers, by using release layers to which the decorative layers are applied and bonding the same to electron-beam-cured adhesive coatings during curing of the same so that the decorative layers may be transferred to the cured-coated substrate by peeling off the release layer.
Abstract:
A transferable flocked fiber design or sticker material which comprises a releasably flocked fiber base including fibers releasably flocked at one end to one major surface of a release support base sheet in upright position by means of a release adhesive layer; and a thermoplastic and pressure-sensitive synthetic resin layer applied to the other end of the flocked fibers. The entire area of the fiber-flocked surface of the release support base sheet is colored or printed or a selected area of the surface is colored or printed in a desired design or pattern and hot melt resin in the form of particles or pellets is sprinkled over the colored or printed surface of the release support base sheet. A method for preparing the releasably flocked fiber base in which a release adhesive layer is formed on one major surface of a release support base sheet, fibers are releasably flocked to the adhesive-applied surface of the release support base sheet and the adhesive-applied surface is colored or printed.

THE RESULTANT SPILT LEATHER POLYURETHANE FILM PRODUCT HAS THE APPERANCE AND OTHER PROPERTIES OF TOP-GRAIN LEATHER.
Abstract:
In a process and apparatus for coating a panel with a resinous composition such as varnish or paint, a coating material which is normally fluid but which hardens under ultraviolet radiation is used. A layer of the composition is deposited on a bed permeable to ultraviolet radiation, and the layer is irradiated through the bed to cause part of its thickness to set. Then the panel is located on the layer and irradiation is continued until the coating has hardened fully.
