SKIN-PATCH PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND SKIN PATCH MATERIAL GIVEN BY USING THE SKIN-PATCH PRESSURE-SENSITIVE ADHESIVE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a skin-patch pressure-sensitive adhesive composition having enough adhesive force when used in skin patch for a long time, without causing remains of adhesive, and to provide a skin patch material.;SOLUTION: This skin-patch pressure-sensitive adhesive composition contains an organosiloxane-based polymer and an acrylic polymer composed mainly of an (meth)acrylic acid ester in a weight ratio of 80 wt%:20 wt% to 0:100 wt% and has a gel fraction percentage of 5% to 65% based on the acrylic polymer component. The skin patch material is formed by using the skin-patch pressure-sensitive adhesive composition. The skin patch material may further has a base material. Further, the skin patch material may be formed so that pressure-sensitive adhesive layers are exposed on both surfaces of the material.;COPYRIGHT: (C)2006,JPO&NCIPI
