ABSTRACT:
Disclosed are silicon-containing nitro dyes for dying organic polymers or organosiloxanes, which are reactive dyes for synthetic or natural fibers of vegetable or animal origin, having the formula: ##STR1## wherein the chromophore component is bonded with the Si-atom by homopolar bonds and wherein X represents the same or different hydrolyzable groups or a siloxane radical, Z is a bivalent alkylene radical with 1-10 carbon atoms which may be interrupted by NR' groups, R is a monovalent organic radical, R' is hydrogen, alkyl with 1-10 carbon atoms, aryl, aralkyl or said substituted radicals, Ar is a substituted or unsubstituted aryl radical, and a and b are integers from 1-3, and a process for making said dyes. Said dyes may be built into a large number of organic and inorganic molecules and color the same without fixation.
