FUNCTIONAL FILM AND METHOD OF MANUFACTURING FUNCTIONAL FILM

摘要

In a case where a functional film that includes an acrylic layer 7, an intermediate layer 8, and a protection layer 9 adjacent to one another on a resin substrate 3, and has the protection layer 9 on its outermost surface is manufactured, the protection layer 9 contains at least a polysiloxane compound, and the intermediate layer 8 contains at least one of the following materials: polyvinyl alcohol resin, polyvinyl acetate, cellulose, and water glass. With this structure, interlayer coupling between the acrylic layer 7 and the intermediate layer 8, and interlayer coupling between the intermediate layer 8 and the protection layer 9 can be strengthened, and detachment of each of the acrylic layer 7, the intermediate layer 8, and the protection layer 9 can be reduced. Accordingly, a functional film that is highly resistant to damage can be obtained.
