Abstract:
This invention provides a method for manufacturing a decorated part having a dynamic visual effect of a design that is drawn onto the surface of a work, thus reducing the manufacturing cost. The decorated part is manufactured by a laser-irradiating process, which involves irradiating a laser onto a decorative surface 4, thus forming a design 20 having many laser-processed linear grooves 21 closely aligned in a specific direction F1 on said decorative surface. Also, in the laser-irradiating process, said design 20 is formed such that the angle θ2 that is made by the specific direction F1 and by the direction F2 in which the laser-processed linear grooves 21 are extending is gradually changing into the direction in which such laser-processed linear grooves are aligned.
Abstract:
A method for preparing a coated substrate that includes (a) applying a photoinitiator to a surface of a substrate; (b) exposing the photoinitiator to ultraviolet or ultraviolet-visible radiation to activate the photoinitiator and form a pre-treated surface; and (c) applying a coating composition to the pre-treated substrate to form a coated substrate. The coating composition may be a nanoparticle-containing emulsion.
Abstract:
The invention relates to a polyester film comprising, on at least one of the faces thereof, a scratch-resistant crosslinked coating. The objective of the invention is to provide a polyester film coated with an abrasion-resistant layer which adheres perfectly to the polyester substrate, and is simple and economical to manufacture. To achieve this objective, the crosslinked hard coating applied to the polyester film comprises: i. 20% to 99% by weight of at least one ester and/or one amide of (meth)acrylic acid comprising a substituted protic group; ii. 20% to 99% by weight of acrylic resin(s); iii. 1% to 40% of a polyalkylene diacrylate; iv. 0 to 50% of at least one derivative of the benzophenone family; v. 0 to 5% of at least one photoinitiator. The invention also relates to the method for obtaining this polyester film coated with an abrasion-resistant hard layer. Use in the production of polyester/metal sheet (steel) colaminate.
Abstract:
An organic molecular film forming apparatus 100 of forming an organic molecular film on a processing target object includes a processing chamber 11 that accommodates therein the processing target object; an organic material gas supplying unit 2 that supplies an organic material gas into the processing chamber 11; and an ultraviolet ray irradiating unit 13 that irradiates ultraviolet ray to at least one of the processing target object, the organic material gas supplied to the processing target object, and a film formed on a surface of the processing target object. At least one of the surface of the processing target object and the organic molecular film formed thereon is activated by irradiating the ultraviolet ray from the ultraviolet ray irradiating unit 13 to at least one of the processing target object, the organic material gas supplied to the processing target object, and the film formed on the processing target object.
Abstract:
A method of electrostatic spraying of a polymer surface involves oxidation and treating the oxidized surface with a polyamine and an electroconductivity modifying agent which contains a mono-carboxylic acid of from one to 12 carbon atoms.
