Abstract:
A pressure-sensitive adhesive excellent in heat resistance and heat-conductivity comprising a photopolymerization product of a composition containing following four components a) to d):a) 100 parts by weight of a monomer mixture (or a partial polymerization product thereof) made up of from 70 to 99% by weight of a (meth) acrylic acid alkyl ester wherein the carbon atom number of the alkyl group is from 2 to 14 on an average and from 30 to 1% by weight of a monoethylenically unsaturated monomer copolymerizable with the (meth)acrylic acid alkyl ester,b) from 0.01 to 5 parts by weight of a polyfunctional (meth)acrylate as a crosslinking agent,c) from 10 to 300 parts by weight of at least one kind of a ceramic powder selected from a covalent bond substance having a total valence electron number of 8 and having a wurtzite-type or zincblende-type crystal structure and a substance having a hexagonal system or graphite structure, andd) from 0.01 to 5parts by weight of a photopolymerization initiator.
