FIELD: chemistry.
SUBSTANCE: invention relates to a water composition with a colouring substance for colouring thermoplastic moulding masses. The composition contains, wt %: from 1 wt % to 49 wt % of modified polyacrylate, including links of alpha-methylstyrene, 2-ethylhexylacrylate and methacrylate of methoxypolyethylene glycol in the form of water solution with concentration from 48 wt % to 52 of polyacrylate, from 0.5 wt % to 50 wt % of the colouring substance or a mixture of colouring substances and completely desalinated water.
EFFECT: invention makes it possible to prevent reduction of softening temperature and increase of sensitivity to rupture effort of polymers.
