Abstract

The invention comprises yellow water-insoluble dyestuffs of formula <FORM:0774676/IV(b)/1> where R is an alkyl or aryl radicle and they may be made by tetrazotising 4, 41 diamino - 3, 31 - dichlorodiphenyl and coupling in substance, or on a substratum suitable for the production of lakes, with a compound of formula <FORM:0774676/IV(b)/2> In examples 4, 41 - diamino - 3, 31 - dichlorodiphenyl is tetrazotised and acid coupled with (1) 1 - acetoacetylamino - 2 - methoxybenzene optionally in the presence of resin soap, (2) 1 - acetoacetylamino - 2 - ethoxybenzene, (3) 1 - acetoacetylamino - 2 - phenoxybenzene in the presence of oleylmethyltaurine and (4) with 1 - acetoacetylamino - 2 - methoxybenzene on an aluminium hydroxide substratum in the presence of resin soap.
