PRESSURE SENSITIVE ADHESIVE SHEET TO IMPROVE TRANSPARENCY AND MOISTURE PERMEABILITY, TO PREVENT INVASION OF WATER, BACTERIA OR VIRUS, AND TO RAPIDLY REMOVE MOISTURE GENERATED BY SWEAT FROM THE SKIN WHILE MAINTAINING GOOD ADHESIVENESS

摘要

PURPOSE: A pressure-sensitive adhesive sheet is provided to improve transparency and moisture permeability, to prevent invasion of water, bacteria or virus, and to rapidly remove moisture generated by sweat from the skin, thereby helping to keep the skin covered with the adhesive sheet in a dried status, and maintaining the good adhesiveness. The adhesive sheet is advantageously used in medicinal or sanitary field. CONSTITUTION: The pressure-sensitive adhesive sheet comprises: (i) an adhesive layer formed by a resin composition comprising acrylic ester polymers, carboxylic esters having C16 or more and a crosslinking component, wherein the carboxylic esters are compatible with the acrylic ester polymers and are present in liquid or paste phase at room temperature; and (ii) a film containing a polyurethane resin for supporting the adhesive layer, wherein the film is obtained by reacting a polyisocyanate component with a polyol component comprising at least one polyether polyol having a polyoxyalkylene backbone with repeating units represented by formula 1: -(O-CH2-RCH)-, wherein R is hydrogen or an alkyl group.
