FOAM COATED WITH PRESSURE-SENSITIVE ADHESIVE AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide an easily applicable and easily re-stickable foam provided with a weakly pressure-sensitive adhesive layer. SOLUTION: The pressure-sensitive-adhesive-coated foam 10 is prepared by laminating a weakly pressure-sensitive adhesive layer 12 on at least either surface of a sheety polyurethane foam 11. The surface of the foam 11 is self- skinning or open-cellular. The layer 12 is made from a liquid reactive polyurethane pressure-sensitive adhesive based on a polyol and isocyanate, and bonds to the foam 11 by reaction to establish a state in which a part of the layer 12 penetrates into the cells of the foam 11.
