Dyeing agent compositions based on polypropylene wax |
| 摘要 |
Preparations of insoluble colorants, especially pigments, are obtained by distributing the colorant in molten polypropylene wax having a viscosity of 0.5 to 5 Pa.s, determined at 170 DEG C., and an isotactic proportion of 40 to 90% by weight. These preparations are easily dispersible in polyolefins and especially useful for dyeing polypropylene in the mass.
