ABSTRACT OF THE DISCLOSURE There are described silane anthraquinone dyes, the com- posite pigments obtainable therefrom by grafting onto an inor- ganic substrate and the corresponding preparation processes. The dyes have the general formula: Image in which R1 is an alkyl containing up to 4 carbon atoms or a phenyl; R2 is an alkoxyl containing up to 4 carbon atoms; n is 3, 4 or 5; q is O or 1; p and m are such integers that, when q is O, p is 3 and m is O, 1, 2 or 3, and when q is 1, p is 2 and m is O, 1 or 2; r is 1 or 2; X represents a divalent amino-NH- or amido- NHCO- residue, linked to the alpha or beta positions of the anthraquinone nucleus when r is 1, or linked to the alpha posi- tions of the anthraquinone nucleus when r is 2 and the anthraquinone nucleus may be substituted by one or more R groups selected from amongst -NH2, -NH-alkyl C1-C4, -NHCO-CH3, -NH- phenyl or -NHCO-phenyl in which the phenyl is optionally substi- tuted, -OH, -OCH3, O-phenyl, -CH3, -Cl or -Br and -NO2. The com- posite pigments obtained from said dyes are utilized in paints, air and stove enamels, in the pigmentation of plastics and in the printing inks.
