    摘要: There are described a new class of organic dyes containing silane groups, the composite pigments obtainable therefrom by associating them with a substrate (SiO.sub.2, TiO.sub.2, Al.sub.2 O.sub.3), and the processes for preparing same.The silane organic dyes have the formula (I): ##STR1## wherein all substituents are defined later. The silane dyes (I) are utilized per se for dyeing natural fibres, such as wool, and man-made fibres, such as the polyamide, polyester, polyacrylic fibres and the like, while the composite pigments prepared from said dyes by association with an inorganic substrate are employed in paints, air enamels and stoving enamels, in the pigmentation of plastics, in the inks, in the printing of textiles etc.

    摘要: 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.
