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.
本发明涉及含有硅烷基的有机染料;通过将该染料嫁接到无机基质上获得的复合颜料;以及制备该染料和复合颜料的相应过程。该染料具有通式:##STR1## 其中R.sub.1和R.sub.2(可以相等或不同)选自包括H,--NH.sub.2,--NHR(其中R是具有1到4个碳原子的烷基或苯基),--NHCOCH.sub.3,--NHCOC.sub.6 H.sub.5,--NO.sub.2,卤素,--OH,--O--C.sub.6 H.sub.5和--S--C.sub.6 H.sub.5的群;n是选自3、4和5的数字;W选自具有1到4个碳原子的烷基和苯基的群;Y是具有1到4个碳原子的烷氧基;q是选自0和1的数字;当q为0时,X为3,m是选自0、1、2和3的数字;当q为1时,x为2,m是选自0、1和2的数字。从该染料获得的复合颜料用于涂料产品、空气漆和烘烤漆中、塑料材料的着色、油墨和织物印刷中。
