Abstract
The invention comprises water-insoluble mono-azo dyes of general formula <FORM:1056354/C4-C5/1> in which R1 is an alkylene radical, R2 is a phenyl, alkyl, or alkoxyalkyl radical and the benzene rings A and B may contain substituents other than sulphonic acid and carboxylic acid groups. Preferably the dyes have the -COOR1OR2 group in the meta or para position to the azo group, R1 is the ethylene radical and R2 is an alkyl group of 1-4 carbon atoms. The dyes are made by coupling the appropriate amine to the required 5-pyrazolone and give red-yellow colours on cellulose acetate, polyamides and polyester materials.
