Abstract
1492683 Chromium complex azo dyes CIBAGEIGY AG 13 Jan 1975 [15 Jan 1974] 1376/75 Heading C4P Novel dyes of the formula (wherein R 1 and R 2 are each phenyl optionally substituted by halogen, C 1-4 alkyl or alkoxy or NO 2 ; one of X 1 , X 2 and X 3 is H and each of the others is H, halogen, NO 2 or CH 3 ; and Me<SP>#</SP> is a cation) are prepared by converting one of the azo dyes of the formulµ to a 1 : 1 chromium complex by reaction with a chromium donor and then reacting this with a non-metallized dye of the other of these formulae. They are used to dye polyamide or polyurethane materials.
