ABSTRACT:
The liquid colorant dispersion intended to be incorporated in plastic materials prior to their transformation and intended to color in bulk these plastic materials comprises a vehicle principally comprising a terpene oil based on pinene and colorant materials. An ethoxylated alkylphenol and other surface-active constituents selected from the group comprising sodium dioctylsulfosuccinate, sodium benzoate, fatty acid condensates, phosphoric ester and alkylpolyalkoxylate may be added to the vehicle. This dispersion compatible with conventional polymers permits obtaining products of a homogeneous coloration, without surface alteration and without distortions.
