Document Type and Number:
WIPO Patent Application WO/2003/013443
Kind Code:
A1
Abstract:
An adhesive for silicone rubber backing materials which comprises (a) 100 parts by weight of an organic solvent, (b) 0.1 to 20 parts by weight of a (meth)acrylic polymer modified with a siloxane having a functional group having hydrosilylation reactivity, and (c) 0.1 to 20 parts by weight of a polymer of an alkyl (meth)acrylate represented by the formula CH2=C(X)−COOR wherein X is hydrogen or methyl and R is C1−6 alkyl. With this adhesive, a silicone rubber backing material can be extremely tenaciously bonded to a (meth)acrylic resin to attain long−lasting adhesion durability. This adhesion durability is obtained even when the organic solvent is a nonhalogenated one.
