PRESSURE SENSITIVE ADHESIVE COMPOSITION FOR THE SKIN, PRESSURE SENSITIVE ADHESIVE COMPOSITION FOR BIOELECTRODE, PRESSURE SENSITIVE ADHESIVE COMPOSITION FOR PERCUTANEOUS ABSORPTION, TAPE FOR THE SKIN, BIOELECTRODE, AND PERCUTANEOUS ABSORBING PREPARATION

摘要

PROBLEM TO BE SOLVED: To provide a pressure sensitive adhesive composition excellent in adhesion to the dry and wet skin, having proper adhesion and coagulating force free from impairing the skin in releasing, free from remaining adhesive, and to provide a pressure sensitive adhesive composition for bioelectrode and a pressure sensitive adhesive composition for percutaneous absorption and a tape for the skin, bioelectrode and a preparation for percutaneous absorption using the same, especially to provide a pressure sensitive adhesive composition for the skin having good adhesive force to the wet skin.

SOLUTION: The invention relates to the pressure sensitive adhesive composition for the skin comprising an acrylic copolymer comprising only 50-88 wt.% of acrylic acid, 8-40 wt.% of 2-ethylhexyl acrylate and 1-42 wt.% of a polar monomer (excluding acrylic acid), and 150-600 pts.wt. of a polyhydric alcohol per 100 pts.wt. of the acrylic copolymer, wherein the composition is then crosslinked by a metal chelate crosslinking agent.
