Abstract
The invention comprises dyes of formula <FORM:0895438/IV (c)/1> where Ar is a tolyl residue, which are made in conventional fashion. The dyes are used for the direct dyeing of polyolefinic materials. The components used in an example are 4-amino-3,21-, -2,31- and -2,21-dimethyl-azobenzene and tetrahydro-b -naphthols and the dyes obtained are yellow and orange. Specification 895,439 is referred to.
