METHOD FOR PRODUCING FOAMED RESIN SELF-ADHESIVE TAPE AND FOAMED RESIN SELF-ADHESIVE TAPE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a foamed resin self-adhesive tape by which the self-adhesive tape having excellent adhesion between a self-adhesive layer and a foamed resin layer can be produced simply.;SOLUTION: The method for producing the foamed resin self-adhesive tape comprises coating an energy ray-curable resin layer exhibiting self-adhesive properties at normal temperature after being cured, and a foamable resin layer prepared by mixing thermally foaming particles in a resin exhibiting the self-adhesive properties at normal temperature after being cured, or an energy ray-curable resin curable without exhibiting the self-adhesive properties, on a separator having releasability such as a release film to form a multilayered coating, and irradiating the multilayer-coated film with the energy ray to cure each coated layer and to afford the foamed resin self-adhesive tape.;COPYRIGHT: (C)2009,JPO&INPIT
