Title:
FUNCTIONAL FILM AND METHOD FOR PRODUCING FUNCTIONAL FILM
Document Type and Number:
WIPO Patent Application WO/2013/180202
Kind Code:
A1
Abstract:
In cases where a functional film, which has such a configuration wherein an acrylic layer (7), an intermediate layer (8) and a protective layer (9) are sequentially formed on a resin base (3) so as to be adjacent to each other, with the protective layer (9) being on the outermost surface, the protective layer (9) is formed to contain at least a polysiloxane compound and the intermediate layer (8) is formed to contain at least one substance that is selected from among polyvinyl alcohol resins, vinyl acetate resins, celluloses and liquid glass. Consequently, the interlayer bonding between the acrylic layer (7) and the intermediate layer (8) as well as the interlayer bonding between the intermediate layer (8) and the protective layer (9) are enhanced, thereby reducing separation of the acrylic layer (7), the intermediate layer (8) or the protective layer (9) and obtaining a functional film that has excellent scratch resistance.
