摘要

PROBLEM TO BE SOLVED: To provide a release-type aqueous pressure-sensitive adhesive sheet, having excellent adhesive force to a base material for clothing, such as a cotton or polyester cloth, especially excellent adhesion at a low temperature, and having excellent heat-resistant adhesive force, and further having excellent heat-resistant and moisture-resistant releasability, to provide a release-type aqueous pressure-sensitive composition, to provide a pressure-sensitive adhesive member for a pasting pocket warmer, given by using the same, and to provide the pasting pocket warmer.;SOLUTION: This release-type aqueous pressure-sensitive adhesive sheet comprises an aqueous pressure-sensitive adhesive sheet having an initial adhesion to the cotton cloth of 1.5 N/25 mm under an atmosphere of 0C. The release-type aqueous pressure-sensitive composition comprises [A] an acrylic resin emulsion and [B] a hydrazine compound, wherein the acrylic resin emulsion [A] is obtained by emulsion polymerization of a monomer mixture containing a (meth)acrylic acid alkyl ester containing a 1-3C alkyl group (a1) in an amount of 1-20 wt.%, a (meth)acrylic acid alkyl ester containing a 4-12 alkyl group (a2) in an amount of 60-98.9 wt.%, an unsaturated monomer containing a carboxyl group (a3) in an amount of 0.1-20 wt.%, an unsaturated monomer containing a carbonyl group (a4) in an amount of 0.01-10 wt.%, and the other unsaturated monomer (a5) in an amount of 0-38.89 wt.% and has a gel fraction of 70 wt.%.;COPYRIGHT: (C)2007,JPO&INPIT
