COLORING PROCESS FOR POLY(METH)ACRYLATES WITH WATER-BASED LIQUID DYES AND WATER-BASED LIQUID DYES

摘要

The invention relates to an aqueous colorant preparation for colouring thermoplastic plastics. By virtue of the use of the inventive aqueous colorant preparation, it is possible in a surprising and unexpected manner, in addition to good colouring of the thermoplastic polymer moulding material, also to keep constant or even increase the Vicat softening temperature of the polymer moulding produced from the coloured thermoplastic polymer moulding material. The remaining mechanical properties of the polymer mouldings remain unchanged.
