Dye concentrate comprising at least one polyisobutene derivative formed from 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, processes for producing the dye concentrates, processes for coloring polymeric materials by contacting the polymeric materials with the inventive dye concentrates, colored polymer compositions formed from at least one inventive dye concentrate and at least one polymeric material, fibers, films, packagings, moldings composed of the inventive colored polymer composition, the use of the inventive dye concentrates for coloring polymeric materials, and the use of polyisobutene derivatives formed from at least one hydrophobic block (X) and at least one hydrophilic block (Y) as assistants for the migration-stable coloring of polymeric materials. The present invention further relates to the process according to the invention for coloring polymeric materials, the polymeric materials additionally being contacted with a block copolymer (component E), the inventive colored polymer 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 inventive use of the inventive dye concentrates for coloring polymeric materials, the polymeric materials being present in a polymer composition which, as well as the at least one polymeric material, has at least one block copolymer E, and the inventive use of polyisobutene derivatives formed from at least one hydrophobic block (X) and at least one hydrophilic block (Y) for the migration- stable coloring of polymeric materials by means of introduction of a dye concentrate, a block copolymer E additionally being introduced.

L~invention concerne un concentré de colorant comprenant au moins un dérivé de polyisobutène constitué d~au moins un bloc hydrophobe (X) et d~au moins un bloc hydrophile (Y) en tant que composant A et au moins un colorant en tant que composant B ; ainsi qu~un concentré de colorant comprenant, en plus des composants A et B, au moins une polyoléfine en tant que composant C1 et/ou au moins un solvant en tant que composant C2. L~invention concerne également un procédé de fabrication de ces concentrés de colorant, un procédé de coloration de matériaux polymériques par mise en contact des matériaux polymériques avec les concentrés de colorant selon l~invention ; des compositions polymériques colorées constituées d~au moins un concentré de colorant selon l~invention et d~au moins un matériau polymérique ; des fibres, des feuilles, des emballages, des corps moulés constitués des compositions polymériques colorées selon l~invention ; l~utilisation du concentré de colorant selon l~invention pour la coloration de matériaux polymériques ; ainsi que l~utilisation de dérivés de polyisobutène constitués d~au moins un bloc hydrophobe (X) et d~au moins un bloc hydrophile (Y) en tant qu~adjuvants pour une coloration stable à la migration de matériaux polymériques. La présente invention concerne également le procédé de coloration selon l~invention de matériaux polymériques, lesdits matériaux polymériques étant en outre mis en contact avec un copolymère séquencé (composant E) ; la composition polymérique colorée selon l~invention comportant en plus dudit ou desdits concentrés de colorant et dudit ou desdits matériaux polymériques au moins un copolymère séquencé (composant E) ; et l~utilisation selon l~invention du concentré de colorant selon l~invention pour la coloration de matériaux polymériques, lesdits matériaux polymériques se présentant sous forme d'une composition polymérique, qui, en plus dudit ou desdits matériaux polymériques, comporte au moins un copolymère séquencé E ; ainsi que l~utilisation selon l~invention de dérivés de polyisobutène constitués d~au moins un bloc hydrophobe (X) et d~au moins un block hydrophile (Y) pour une coloration stable à la migration de matériaux polymériques par utilisation d~un concentré de colorant comportant en outre un copolymère séquencé E.
