    摘要： Dye concentrate comprising at least one polyisobutene derivative composed of at least one hydrophobic block (X) and at least one hydrophilic block (Y) as component A and at least one dye as component B and also a dye concentrate which, as well as components A and B, comprises at least one polyolefin as component C1 and/or at least one solvent as component C2, production of the dye concentrates, coloration of polymeric materials by contacting the polymeric materials with the dye concentrates of the present invention, colored polymeric compositions composed of at least one dye concentrate of the present invention and at least one polymeric material, fibers, films, packaging, moldings composed of the colored polymeric composition of the present invention, the use of the dye concentrates of the present invention for coloration of polymeric materials, and also the use of polyisobutene derivatives composed of at least one hydrophobic block (X) and at least one hydrophilic block (Y) as an auxiliary for migration-resistant coloration of polymeric materials. The present invention further concerns the present invention's process for coloration of polymeric materials wherein the polymeric materials are additionally contacted with a block copolymer (component E), the present invention's colored polymeric composition which, as well as the at least one dye concentrate and the at least one polymeric material, comprises at least one block copolymer (component E) and the present invention's use of the present invention's dye concentrates for coloration of polymeric materials wherein the polymeric materials are present in a polymeric composition which, as well as the at least one polymeric material, comprises at least one block copolymer E, and also the present invention's use of polyisobutene derivatives composed of at least one hydrophobic block (X) and at least one hydrophilic block (Y) for migration-resistant coloration of polymeric materials by incorporation of a dye concentrate wherein additionally a block copolymer E is incorporated.

    摘要： A process for resolving the racemates of phenylacetonitriles of the formula I ##STR1## where R.sup.1, R.sup.2, R.sup.3 and m have the meanings stated in the description is described. The process comprises dissolving the racemates I in a polar solvent, adding from 0.5 to 1.0 mol of optically active camphorsulfonic acid per mol of compound I, heating to 40.degree.-100.degree. C., allowing to cool and liberating the optically active phenylacetonitrile I from the salt obtained in this way.
