Abstract

Abstract Velvet type fasteners are imparted with pressure sensitive adhesion by applying to the respective back surfaces of the male and female pieces of a velvet type fastener, a composition consisting of: 100 parts by weight of a polymer, containing at least 65 percent mol of an ester of an acrylic acid or methacrylic acid and from 0.2 to 5 parts by weight of glycidyl ester of an unsaturated organic acid; from 0.5 to 5 parts by weight of a zirconyl salt of organic acid, and; from 0.01 to 0.1 part by weight of a volatile acid addition salt of organic amine.
