1. A colorant-including composition comprising:
- (A) at least one colorant,(B) at least one organopolysiloxane containing units of the general formula
Ra(R1O)bSiO[4−
(a+b)]/2
(I),whereR may be identical or different and is a monovalent, SiC-bonded, optionally substituted hydrocarbon radical which may be interrupted by heteroatoms,R1 may be identical or different and represents hydrogen atom or a monovalent, optionally substituted hydrocarbon radical which may be interrupted by heteroatoms,a is 0, 1, 2 or 3, andb is 0, 1, 2 or 3,with the proviso that the sum a+b≤
3 and in more than 80% of all units of the formula (I) a is 2, and also(C) at least one siloxane-organo copolymer, the organic segments in the copolymers (C) comprising (co)polymers of (methyl) methacrylate, of polyalkylene oxides, or comprising polyester segments.

Abstract
The invention relates to compositions containing dye, containing (A) at least one dye, (B) at least one organopolysiloxane containing units of the general formula Ra(R1O)bSiO[4−(a+b)]/2 (I), wherein the radicals and indexes have the meaning indicated in claim 1, provided that the total is a+b≤3 and in more than 80% of all units, the formula (I) is equal to 2, and (C) at least one siloxane-organo-copolymer. The invention further relates to a method for the production thereof and to the use thereof in the dyeing of polymer materials.
