Abstract
The present invention provides an alkali soluble pressure sensitive adhesive composition comprising 100 parts by weight of a polymer obtained by polymerization of carboxyl group-containing vinyl monomer as an adhesive component and 50-500 parts by weight of a nonionic surface active agent capable of endowing plasticity as a main additive component. The tack papers or the adhesive tapes using the adhesive compositions according to the invention can be readily dissolved in alkali water in the step of repulping and the reclaimed papers without adhesiveness can be prepared with them. Further, the alkali soluble pressure sensitive adhesive compositions of the present invention are excellent in moisture dependence, tack properties at low temperatures and bleeding properties at high temperatures. Especially, the compositions are improved in shearing strength by adding cross-linking agents and are improved in adhesiveness to glass by adding silane coupling agents, and so are suitable for labels and the like of beer bottles, etc.
