COPOLYMER CONTAINING REACTIVE SILYL GROUPS, COMPOSITION CONTAINING THE SAME, AND METHOD OF TREATMENT WITH THE SAME

摘要

A composition of the present invention comprises a copolymer having silyl groups at least one reactive functional group bonded thereto. The copolymer preferably comprises, as one of constitutive monomers, Monomer (A) shown by the following Formula (I): wherein R1 is hydrogen atom or methyl; R2 alkylene group having 1-6 carbon atoms; and R3, R4 and R5 each is a reactive functional group which can cross-link molecules of the copolymer by hydrolyzing. Further, the copolymer preferably comprises, as a constitutive monomer, an alkyl (meth)acrylate and a siloxane-containing (meth)acrylate. The coat-forming method of the present invention comprises hydrolyzing the composition on a material to be treated to cross-link molecules of the copolymer,thereby forming a coat of the cross-linked copolymer having excellent resistance to washing. This coat can exhibit hair nature modifying effect, make-up retention improving effect, and skin-protecting effect. Also, it can impart water-repellency, unsusceptibility to fouling, suitability for sizing and crease resistance to fibers. Further, it can improve skin-cleaning effect, applicability, strippability and coat-strength of a peeling-off type cosmetic pack.
