PURPOSE:To obtain titled composition with outstanding cohesive force and high adhesivity, by polymerizing, in the presence of a cellulose ester, a speific acrylic ester, etc. to prepare a polymer with a specific glass transition paint, resulting in specific weight ratio of said cellulose ester to the polymer. CONSTITUTION:The objective composition can be obtained by polymerizing, in the presence of (A) a cellulose ester (pref., cellulose acetate butyrate), (B) (i) an acrylic ester having 4-12C alkyl group (e.g., butyl acrylate) or plus (ii) an ethylenic unsaturated monomer copolymerizable with the component (i) (e.g., ethyl acrylate) so that the polymer from the component (B) has a glass transition point <=-25 deg.C. The weight ratio of the component (A) to the component (B) should be 1-35/99-65.
