Abstract: Process for improvement of the elasticity of a colored polymer system, which is composed of a matrix and of discrete polymer particles distributed in accordance with a defined spatial lattice structure in the matrix, and which is obtained by filming of an emulsion polymer with core/shell structure, where the emulsion polymer is obtainable via polymerization of monomers in at least one first stage (monomers of the core) and subsequent polymerization of monomers in at least one further, second stage (monomers of the shell), which comprises using monomers whose glass transition temperature is below 0° C. as at least 5% by weight of the monomers of the core.

Abstract: A method for improving the color brilliance of a colored polymer system (I) comprising a matrix and discrete polymer particles distributed according to a definite lattice structure and obtained by forming a film of an emulsion polymer with a core/shell structure made by two-stage emulsion polymerisation, in which ionic emulsifiers are used for polymerising the core monomers and non-ionic emulsifiers for polymerising the shell monomers, or vice versa. Independent claims are included for (1) colored polymer systems (I) obtained by this method (2) a method for the production of substrates coated with (I) by coating (I) onto a temporary support (e.g. by film formation or by extrusion), transferring the support with the coating onto the substrate (e.g. by lamination or pressing) and optionally removing the temporary support.

Abstract: A method for improving the elasticity of a colored polymer system (I) comprising a matrix and discrete polymer particles distributed according to a definite lattice structure and obtained by forming a film of an emulsion polymer with a core/shell structure made by two-stage emulsion polymerisation, in which the monomers for the shell are added to the polymerisation mixture in less than 90 minutes. Independent claims are included for (1) colored polymer systems (I) obtained by this method (2) a method for the production of substrates coated with (I) by coating (I) onto a temporary support (e.g. by film formation or by extrusion), transferring the support with the coating onto the substrate (e.g. by lamination or pressing) and optionally removing the temporary support.
