Abstract:
A process for producing a film of a hydrophilic polymer on the inner surfaces of a fluidic component is provided comprising subjecting the inner surfaces of the fluidic component to a physicochemical pre-treatment, contacting the inner surfaces of the fluidic component with a solution of the hydrophilic polymer, replacing the solution of the hydrophilic polymer with a gaseous medium in such a manner that firstly the inner surfaces of the fluidic component remain wetted with part of the polymer solution, and removing the solvent to produce a film of the hydrophilic polymer on the inner surfaces of the fluidic component. The hydrophilic polymer used has a surface wettability for aqueous solutions which is higher than the surface wettability of the inner surfaces of the fluidic component itself.
Abstract:
The present invention relates to an anti-reflection film for preventing the reduction of image quality caused by light reflection in various display screens, such as CRT, liquid crystal displays (LCD) and plasma display panels (PDP). The anti-reflection film 100 comprises a substrate consisting of a transparent polymer film 110, and at least one conductive polymer layer 120 formed by depositing a heterocyclic conjugated polymer on at least one surface of the substrate. Thus, the inventive anti-reflection film has high transparency and small thickness, and anti-static and/or electromagnetic shielding properties, such that it can be widely used in electrical, mechanical and electronic fields.

Abstract:
In a surface treatment method of treating the surface of a material to be treated, by irradiating with light the material to be treated and a mediating material in contact with each other, the mediating material itself causes substantially no interaction upon irradiation with light. The surface of the material to be treated is treated by provision of a chemical reaction field, in which a substituent of the material to be treated and an atom of atomic group of the mediating material is induced by excitation, by irradiating with light by using the logical product of the contact interface between the material to be treated and the mediating material and the light irradiation region, thereby causing and progressing bonded state transition.
Abstract:
A process for the production of coated planar moldings of thermoplastics is disclosed. The process entails extrusion of a molded body, cooling of the molding, applying the aqueous-based coating agent and drying. The coating agent, having a pH value of less than 6, contains a salt of sulfondicarboxylic diester, a water-insoluble oxide of metal or semi-metal and an acid/water mixture. It is applied to at least one surface of the molding immediately after the production of the molding and with the aid of an application roll.
Abstract:
Articles produced from hydrophobic polymers (e.g., polyethylene) are surface-coated with thin films of starch in order to render the surfaces hydrophilic. The thin coatings form on the surfaces of plastic objects when the objects are placed in contact with hot, aqueous solutions of starch. These starch coatings are extremely adherent to the hydrophobic plastic surfaces under both wet and dry conditions, and they permit the surfaces to be uniformly wet with water. Resultant products have improved biocompatibility, improved compatibility with hydrophilic reagents, reduced build-up of electrostatic charge, reduced blocking, reduced friction, improved absorption of water-based dyes, and improved adhesion properties. The starch coatings are non-toxic, inexpensive and biodegradable.

It is an object of the present invention to provide a method of coating a plastic molding which is appropriately applicable to various plastic substrates, an ultraviolet-curable under coating for metal evaporation, which is to be used in that method of coating, and a plastic molding obtained by that method of coating. A method of coating a plastic molding comprising steps of applying an ultraviolet-curable under coating for metal evaporation to a plastic substrate, then subjecting the coated substrate to ultraviolet irradiation to form an under coating film, evaporating a metal on the coating film and applying a clear coating to the metal surface to form a clear coating film layer, wherein the ultraviolet-curable under coating for metal evaporation comprises an acrylic resin comprising, as a constituent, at least one monomer (a) selected from among dicyclopentanyl (meth)acrylate, dicyclopentenyl (meth)acrylate and isobornyl (meth)acrylate, a compound having at least two (meth)acryloyl groups within the molecule, and a photopolymerization initiator.
Abstract:
Injection stretch blowmolded polyester tubes have been developed for use in packaging water-containing products. Polyester resins have good barrier properties for organic materials but poor moisture barrier properties. It has been found that the moisture barrier properties can be increased by coating the exterior surface of the tube with a first material which adheres to the tube polyester surface and to an overlayer of a moisture barrier comprising polyvinylidene chloride, However, since the overlayer of polyvinylidene chloride can develop a yellow tint, the overlayer in one embodiment is coated with an opaque decorative layer to prevent or mask the gradual yellowing of the polyvinylidene chloride overlayer. In another embodiment where the tube is to be substantially transparent, the product in the tube will have a color that will substantially cancel the yellow tint that is developed by the polyvinylidene chloride overlayer. In a further embodiment the tube is of a color to cancel out the yellow tint color of the polyvinylidene chloride layer. The moisture transmission of the tube wall in any of the embodiments is reduced to less than about 1 gram/m2/day. In a preferred embodiment both the tube wall and the upper tube shoulder have this coating structure to decrease moisture loss from the contained product through both the tube shoulder and the sidewall.
