Silicone-containing fabric finishing agent

Claim 1

A fabric finishing agent in the form of a solution in: (A) a volatile inert organic solvent of (B) a graft copolymer product of a graft copolymerization of from 5 to 95 parts by weight of (a) an organopolysiloxane represented by the general formula xo--(--SiR.sub.2 --O--).sub.m --(--SiYR--O--).sub.n --X, in which each R is a substituted or unsubstituted monovalent hydrocarbon group of 1 to 20 carbon atoms, Y is a monovalent radical-polymerizable group or a monovalent organic group having a mercapto --SH group, X is a hydrogen atom, lower alkyl group or triorganosilyl group of the formula R 2 R 1 Si--, R having the same meaning as defined above and R 1 being R or Y, m is a positive integer not exceeding 10,000 and n is a positive integer, and from 95 to 5 parts by weight of (b) an acrylic or methacrylic monomer represented by the general formula CH.sub.2 ═CR.sup.2 --CO--OR.sup.3, in which R 2 is a hydrogen atom or a methyl group and R 3 is an alkyl group or an alkoxy-substituted alkyl group having 1 to 18 carbon atoms, alone or as a mixture of monomers (b-1) at least 70% by weight of which is an acrylic or methacrylic monomer (b) as defined above, and one or both of (b-2) up to 30% by weight of which is an ethylenically unsaturated monomer containing one and only one radical-polymerizable ethylenically unsaturated group and at least one functional group in the molecule selected from the group consisting of hydroxy, hydroxy-terminated polyoxyalkylene, carboxyl, oxirane, amido, N-alkylolamido, N-(alkoxyalkyl)amino and amino groups and (b-3) up to 20% by weight of which is another radical-polymerizable ethylenically unsaturated monomer different from monomers (b-1) and (b-2) defined above, in the presence of a radical polymerization initiator and dissolved in component (A).
