Patent ID: 7759421

Claim:
A resin composition comprising: a matrix; and a filler (C) comprising a metal hydroxide having an average particle diameter of 0.5 to 30 μm and showing a decomposition temperature of 250° C. or higher, present in an amount of 150 parts by weight or more per 100 parts by weight of the acrylic copolymer (A); the matrix comprising: an acrylic copolymer prepared by copolymerization of two or more different monomers and having a glass transition temperature (Tg) or −60° C. to −20° C. as determined by differential scanning calorimetry or a blend of two or more acrylic homopolymers or a blend of two or more acrylic homopolymers and acrylic copolymers or a blend of two or more acrylic copolymers, wherein the major constituent polymer of the acrylic copolymer has a glass transition temperature of −60° C. to −20° C. as determined by differential scanning calorimetry; and a compound (B) containing two or more glycidyl groups per molecule having a weight per epoxide (WPE) of 80 to 400.
