NONAQUEOUS PRESSURE-SENSITIVE ADHESIVE COMPOSITON, PATCHES AND PROCESS FOR PRODUCTION OF PATCHES

摘要

A kind of nonaqueous pressure-sensitive adhesive composition, which is characterized in that containing there are two non-soluble polymer (one) with the B for being capable of forming crosslinking points Yu polyvalent metal ion and polyvalent metal compounds; The patche of acquisition passes through laminate substrate and the composition; With production patch, it is characterized in that, including preparation disappearance polyvalent metal compounds chelating agent (B groups) and (C groups) can with formation chelate compound (B groups) in aqueous solvent, by acquired solution tune pH to 7 or more, it mixes obtained solution and non-soluble polymer (one) there is functional group to be capable of forming and prepare water-borne dispersions with multivalent metallic ion crosslinking point, the dispersion applies on lining or matrix, and dry obtained coating is formed on non-aqueous pressure-sensitive adhesive layer.
