Abstract
This invention relates to organic dyes containing silane groups; composite pigments obtainable by grafting said dyes onto an inorganic substrate; and, the respective processes for preparing said dyes and composite pigments. The dyes have general formula: ##STR1## wherein R.sub.1 and R.sub.2, which may be equal or different, are selected from the group consisting of H, --NH.sub.2, --NHR wherein R is an alkyl group having from 1 to 4 carbon atoms or a phenyl group, --NHCOCH.sub.3, --NHCOC.sub.6 H.sub.5, --NO.sub.2, a halogen, --OH, --O--C.sub.6 H.sub.5 and --S--C.sub.6 H.sub.5 ; n is a number selected from 3, 4 and 5; W is selected from the group consisting of an alkyl group having from 1 to 4 carbon atoms and a phenyl group; Y is an alkoxy group having from 1 to 4 carbon atoms; q is a number selected from 0 and 1; X is 3 and m is a number selected from 0, 1, 2 and 3 when q is 0; x is 2 and m is a number selected from 0, 1 and 2 when q is 1. The composite pigments obtained from said dyes are employed in the painting products, air enamels and stoving enamels, in the pigmentation of plastic materials, in the inks and in the printing of fabrics.
