Abstract

A process for producing a plate-like body with a resin frame having a decorative molding, wherein the decorative molding includes a main part and a film formed on a surface and has a design part exposed on a surface of the resin frame and an embedded part in the resin frame. The film continuously covers the design part and the embedded part. The process includes a step of mounting the decorative molding on a mold for forming the resin frame and further mounting a plate-like body, and a step of injecting a molten resin into a cavity of the mold and forming a resin frame with the decorative molding thereon into a window glass while a film at a portion located at a boundary between the design part and the embedded part is pressed against the mold by an injection pressure of the molten resin and thermally deformed.

First claim

What is claimed is:

1 . A process for producing a plate-like body with a resin frame having a decorative molding provided on the resin frame of the plate-like body with a resin frame, wherein the decorative molding comprises a main part and a film formed on a surface of the main part and has a design part exposed on a surface of the resin frame and an embedded part embedded in the resin frame, and the film is disposed so as to continuously cover the design part and the embedded part, the process comprising:
a mounting step of mounting the decorative molding on a mold for forming the resin frame and further mounting a plate-like body on the mold, and a resin frame-forming step of injecting a molten resin into a cavity space of the mold and forming a resin frame having the decorative molding mounted thereon on the plate-like body while a portion located at a boundary between the design part and the embedded part of the film is pressed against the mold by an injection pressure of the molten resin and thermally deformed.

2 . The process for producing a plate-like body with a resin frame according to claim 1 , wherein in the resin frame-forming step, at least a part of the film at the portion located at a boundary between the design part and the embedded part, is plastically deformed so as to have a thickness of at least 10% and at most 90% of the thickness of the film at the other portion.

3 . The process for producing a plate-like body with a resin frame according to claim 1 , wherein the design part of the decorative molding has a flat part and a connecting part connecting the flat part and the embedded part, the connecting part is formed as inclined in an out-of-plane direction to the flat part.

4 . The process for producing a plate-like body with a resin frame according to claim 1 , wherein the main part comprises a metal material.

5 . The process for producing a plate-like body with a resin frame according to claim 1 , wherein the film comprises at least one resin selected from a polyvinyl chloride resin, an acrylic resin, a polyester resin and a polyvinylidene fluoride resin.

6 . The process for producing a plate-like body with a resin frame according to claim 1 , wherein the film has a colored layer and an adhesive layer, and the colored layer has a similar color to the color of the resin frame or a vehicle body.

7 . The process for producing a plate-like body with a resin frame according to claim 5 , wherein the molten resin and the film comprises similar resins.

8 . A plate-like body with a resin frame having a decorative molding provided on the resin frame of the plate-like body with a resin frame,
wherein the decorative molding comprises a main part and a film formed on a surface of the main part, and has a design part exposed on a surface of the resin frame and an embedded part embedded in the resin frame, and the film is disposed so as to continuously cover the design part and the embedded part, and at least a part of the film at a portion located at a boundary between the design part and the embedded part of the film has a thickness of at least 10% and at most 90% of the thickness of the film at the other portion.

9 . The plate-like body with a resin frame according to claim 8 , wherein the decorative molding and the resin frame are an integrally formed product.

10 . The plate-like body with a resin frame according to claim 8 , wherein the design part of the decorative molding has a flat part and a connecting part connecting the flat part and the embedded part, and the connecting part is formed as inclined in an out-of-plane direction to the flat part.
