DERMAL PRESSURE-SENSITIVE ADHESIVE SHEET MATERIAL

摘要

A dermal pressure-sensitive adhesive sheet material which comprises a backing having provided on one side thereof a pressure-sensitive adhesive layer is disclosed, in which said pressure-sensitive adhesive layer contains a copolymer comprising from 40 to 80% by weight of an alkyl acrylate or methacrylate monomer, from 10 to 50% by weight of an alkoxyl-containing ethylenically unsaturated monomer, and from 1 to 10% by weight of a carboxyl-containing ethylenically unsaturated monomer and having a glass transition point of 250 DEG K or lower and a gel fraction after drying of 25% or more. The dermal pressure-sensitive adhesive sheet material causes no irritation to the skin, behaves like the skin as having low modulus of elasticity, and exhibits high moisture-permeability and excellent resistance to bacteria and water.
