Benefits of technology
The patent aims to prevent peeling and functional loss of the film in a glass resin laminate. The technical effect is to improve the durability of the film.
Problems solved by technology
As is well known, glass is excellent in weather resistance, chemical resistance, and scratch resistance, but by contrast, has a drawback in that the glass is liable to break owing to physical impact or thermal impact.

Abstract
Provided is a glass resin laminate (1), including: a resin layer (2); a glass sheet (3); an adhesive layer (4) configured to bond the glass sheet (3) and the resin layer (2); and a functional film (5) interposed in the adhesive layer (4). The adhesive layer (4) includes a first portion (4a) positioned between the resin layer (2) and the functional film (5), a second portion (4b) positioned between the glass sheet (3) and the functional film (5), and a fused portion (4c) obtained by fusing an end portion of the first portion (4a) and an end portion of the second portion (4b).
Description
TECHNICAL FIELD[0001]The present invention relates to a glass resin laminate obtained by laminating a glass sheet and a resin layer.BACKGROUND ART[0002]As is well known, glass is excellent in weather resistance, chemical resistance, and scratch resistance, but by contrast, has a drawback in that the glass is liable to break owing to physical impact or thermal impact. In order to solve the drawback, for example, a glass resin laminate obtained by bonding a resin layer to one surface, or each of both surfaces, of a glass sheet has been proposed. A resin is inferior in weather resistance, chemical resistance, and scratch resistance to the glass, but by contrast, has an advantage in that the resin has a specific gravity smaller than that of the glass and is strong against the physical impact. Accordingly, in the glass resin laminate, respective demerits in the glass sheet and the resin layer can be compensated with their respective merits. In addition, the laminate can be significantly ...
