ABSTRACT:
Silane quinacridone dyes, composite pigments obtainable therefrom by association with an inorganic substrate, and the processes for preparing them. The dyes have the general formula: ##STR1## wherein X is an --SO.sub.2 NHR group, where R is an alkyl group, linear or branched, having from 1 to 6 carbon atoms, a cycloalkyl group, a phenyl group optionally substituted by one or more alkyl or alkoxy groups (C.sub.1 -C.sub.6), a halogen; Y and Z indicate a silane group having the formula: ##STR2## wherein R.sub.1 is an alkoxy group (C.sub.1 -C.sub.2), R.sub.2 is an alkyl group (C.sub.1 -C.sub.4) or a phenyl group; n is 3, 4 or 5; q is 0 or 1; p and m are integers, such that when q is 1, p is 2 and m is 0, 1 or 2, and when q is 0, p is 3 and m is 0, 1, 2 or 3; W indicates an --SO.sub.3 H group; a, b and c are 0 or 1, selected in such a way that the sum a+b+c is equal to 1.
The composite pigments obtained from said dyes are used in paints, air enamels and stove enamels, in the pigmentation of plastics, and in printing inks.
