PURPOSE:To provide the titled dispersion liquid composed of internally crosslinked fine particle of pressure-sensitive adhesive obtained by the copolymerization of specific monomers, a binder consisting of a styrene- containing polymer having small particle size and an organic solvent and leaving no residual adhesive particles on an adherend after peeling off a pressure- sensitive adhesive sheet. CONSTITUTION:The objective dispersion liquid is composed of (A) 100pts.(wt.) of internally crosslinked pressure-sensitive adhesive particles having particle diameter of 5-200mu and obtained by copolymerizing (i) 2-10(wt)% methyl acrylate and/or styrene and/or methacrylate of 1-5C alcohol, (ii) 98-90% acrylate of 2-12C alcohol and/or methacrylate of 6-12C alcohol, (iii) 0.1-2% maleic anhydride and (iv) 0.05-1% tetraallyloxyethane or triallyl (iso)cyanate, (B) 2-20pts. of styrene-containing polymer having a styrene content of 5-70% and particle diameter of 0.02-3mu and acting as a binder of the particle A and (C) an organic solvent.
