Abstract
The invention comprises water-insoluble dyes of the formula <FORM:0973930/C4-C5/1> in which X denotes an oxygen atom or a sulphur atom, R1 denotes a hydrogen atom, a halogen atom, an alkyl radical, the 1-pyrrolidone radical or an amino group wherein one hydrogen atom is substituted by an acyl radical derived from a carboxylic acid or the carbomethoxy radical and R2 denotes a halogen atom, an alkyl radical, the 1-pyrrolidone radical or an amino group wherein one hydrogen atom is substituted by an acyl radical derived from a carboxylic acid, or the carbomethoxy radical. Such dyes are obtained by coupling tetrazotized 4,41-diaminodiphenyl-urea or -thiourea with appropriate phenols. The dyes are suitable for dyeing and printing cellulose esters, polyamides, polyurethanes and polyesters, e.g. polyethylene terephthalate. Among the many coupling components specified in examples are 1-hydroxy - 4 - methyl benzene, a mixture of 1-hydroxy - 4 - methyl - and - 4 - acetamino benzenes, a mixture of 1-hydroxy-4-methyl-and -3,4-dimethylbenzenes, a mixture of 1-hydroxy-4-methylbenzene and 1-(4-hydroxyphenyl)-pyrrolidone and a mixture of 1-hydroxy-4-methyl-and 1 - hydroxy - 4 - carbomethoxyamino - aminobenzenes.
