Abstract
Abstract Silane diimidic tetracarboxylic perylene dyes, the composite pigments obtainable therefrom by means of grafting onto an inorganic substrate, and the processes for preparing same. The dyes have the general formula: <IMAGE> (I) in which R is the residue of a silane group of formula: <IMAGE> (II) in which n is 3, 4 or 5; q is 0 or 1, p and m are such integers than when q is 0, p is 3 and m is 0, 1, 2 or 3, and when q is 1, p is 2 and m is 0, 1 or 2; R2 is an alkyl C1-C4 or a phenyl; R3 is an alkoxyl C1-C2; R1 may be the same as R or represent an alkyl C1-C6, a cycloalkyl, a phenyl optionally substituted by one or more alkyl or alkoxyl groups C1-C6 or a halogen. The dyes and the composite pigments obtained from said dyes are utilized in paints, air and stove enamels, in the pigmentation of plastic materials, and in printing inks.
