<p>It is an object of the present invention to provide a laminate having excellent weatherability and abrasion resistance as well as adhesion. The present invention relates to a laminate comprising a base, a first layer formed by thermally curing an acrylic resin composition and a second layer formed by thermally curing an organosiloxane resin composition, all of which are formed in the mentioned order, wherein
the acrylic resin composition comprises:
(A) an acrylic copolymer which contains at least 70 mol% of a recurring unit represented by the following formula (A) :
wherein X is a hydrogen atom or methyl group, and Y is a methyl group, ethyl group, cycloalkyl group, hydroxyalkyl group having 2 to 5 carbon atoms or triazine-based ultraviolet absorber residue;
(B) a blocked polyisocyanate compound;
(C) a curing catalyst; and
(D) a triazine-based ultraviolet absorber, and
the organosiloxane resin composition comprises:
(E) colloidal silica and (F) a hydrolysis condensate of an alkoxysilane.</p> |
