PROBLEM TO BE SOLVED: To form images with superior peelable property, high coloring density, and excellent vividness by forming out of copolymer of silicone macro monomer and vinyl monomer. SOLUTION: The copolymer is formed of a polymer produced by an emulsion polymerization of silicone macro monomer and vinyl monomer. Besides, representative silicone macro monomer an be indicated by a formula I or II, and in the formulas I, II, R<1> shows a hydrogen atom or a methyl group, R<2> indicates a C2-4 alkylene group, R<3> expresses an alkyl group or an aryl group, and (n) shows an integral number of 10-150. Herein, vinyl ester or its class is used for, e.g. a vinyl monomer. The rate between silicone macro monomer and vinyl monomer is of the order of silicone macro monomer/vinyl monomer=10/90-60/40 (weight ratio). Also, polymer particles obtained by emulsion polymerization are on the order of 0.01-1 μm in its mean particle diameter. |
