ABSTRACT:
A process for the mass coloration of organic material of high molecular weight, which comprises the use of a mixture of anthraquinone compounds of the formula: ##STR1## wherein n is 1 or 2, R, if n is 1, represents a substituted or unsubstituted anthraquinone radical, and, if n is 2, R represents a radical of the formula: ##STR2## wherein R.sub.1 represents hydrogen, alkyl of 1 to 4 carbon atoms, phenyl or methylmercapto as colorant, having good thermostability, solubility when incorporated in the polymer melt, and resistance to the staining of other material during thermofixation.
