ACRYLIC PRESSURE-SENSITIVE ADHESIVE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain an acrylic pressure-sensitive adhesive composition that is suitably useful for tentative fixation of curing sheets which are used for coating or processing a relatively large space, for example, ceilings, floors and wall faces. SOLUTION: This acrylic pressure-sensitive adhesive composition comprises (A) an acrylic copolymer that bears an amide group and a hydroxy group, but includes no carboxy group in the molecule and has the glass transition point (Tg) of <=-35 deg.C and (B) a polyisocyanate originating from tolylene diisocyanate as essential components.
