PRESSURE SENSITIVE ADHESIVE SHEET FOR PAPER DIAPER INSIDE AND PAPER DIAPER

摘要

PROBLEM TO BE SOLVED: To provide a pressure sensitive adhesive sheet for a paper diaper inside and a paper diaper, even if being directly stuck to the skin, preventing the skin surface from getting stuffy and preventing contact dermatitis and flare by infiltrating moisture caused by sweating.;SOLUTION: This pressure sensitive adhesive sheet for the paper diaper inside is used, when the paper diaper is worn, by being fixed to the inside of the paper diaper in such a form that the pressure sensitive adhesive layer surface can directly contact with the skin of a wearer, and the water-vapor transmission ratio (under a temperature 40°C, a humidity 30 %RH and the thickness of the pressure sensitive adhesive 100 μm) of the pressure sensitive adhesive is 800 g/m² day or more. Alternatively, when the paper diaper is worn, the pressure sensitive adhesive layer surface is fixed to the inside of the paper diaper in such a form as to directly contact with the skin of the wearer and the pressure sensitive adhesive layer comprises pressure sensitive adhesive mainly composed of polyether-based copolymer having at least single alkenyl group in a molecule.;COPYRIGHT: (C)2005,JPO&NCIPI
