摘要：
The present invention provides a water-dispersed acrylic PSA composition suitable for forming a PSA sheet. The PSA composition contains 0.5 to 15 parts by weight of an acrylic copolymer (polymer H) with a Tg of 30° C. to 120° C. in relation to 100 parts by weight of an acrylic copolymer (polymer L) with a Tg of −70° C. to −50° C. The polymer L is obtained by polymerization of a monomer starting material comprising 60 wt % or more of an alkyl (meth)acrylate with a C8-C12 alkyl group; and 0.5 to 10 wt % of a radical polymerizable monomer with a carboxyl group.
