<p><P>PROBLEM TO BE SOLVED: To provide a composition for production of a crosslinkable pressure-sensitive adhesive for skin, having satisfactory pressure-sensitive adhesion and releasability for human skin, low in irritation, suitable for medical and cosmetic uses, suitable for production, and having superior preservability. <P>SOLUTION: The composition is formed with 100 pts.mass acrylic copolymer (copolymer A) comprising an alkyl (meth)acrylate as a main constituent, and 3-45 mass% diacetone acrylamide as an essential constituent, and containing no free carboxy group, and 0.1-30 pts.mass acrylic copolymer (copolymer B) comprising an alkyl (meth)acrylate as a main constituent and a primary amino group and/or carboxyhydrazide group on a side chain, and containing no free carboxy group. The copolymer B contains two or more primary amino groups and/or carboxyhydrazide groups in one molecular chain, and the primary amino groups and/or carbohydrazide groups in the copolymer B are contained at a ratio of one in 5-100 molecular chains of the (meth)acrylate comonomer. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
