Abstract

PURPOSE: The titled composition, containing an addition polymerization polymer obtained by post-polymerizing an acrylic polymer havng the tackiness at room temperature with a specific ethylenically unsaturated monomer, and capable of giving a high cohesive force and adhesive force even without using a crosslinking agent.
CONSTITUTION: A composition containing an addition polymer obtained by (co) polymerizing (B) an ethylenically unsaturated monomer capable of giving the glass transition point ≥273°K of the homopolymer and copolymer and a haze value ≥15% of a polymeric film (having a thickness of 50μ) formed from a belnd of the polymer with (A) an acrylic polymer having the tackiness at room temperature in the presence of the component (A). The component (B) is preferably selected from the group of styrene, vinyl acetate and (meth) acrylonitrile having the glass transition point ≥300°K of the homopolymer and the group of (meth) acrylic esters and styrne derivatives having the glass transition point ≥273°K, preferably methyl methacrylate.
