(A) and from about 15 to about 85 parts by weight (meth) acrylate ester monomer having a polymerizable makes it approximately 10 ° C. less than the glass transition temperature (T g), (b) from about 85 to about 15 parts by weight of a hydrophilic acidic comonomer And (c) at least about 10 parts of a non-reactive plasticizer, based on a total of 100 parts of components (a) + (b), and a styrene block comprising copolymerized styrene and isoprene, butadiene or ethylene-butylene. Copolymer (eg, linear, linear, tapered, star), polyisoprene, polybutadiene, polyisobutylene, butyl rubber, styrene-butadiene rubber, natural rubber, and poly-α-olefin (eg, polyhexene) , Polyoctene, and propylene-hexene), and the like. An adhesive formulation comprising a hydrophilic pressure-sensitive adhesive, comprising a polymerization product with a hydrophobic pressure-sensitive adhesive. |
