Abstract

The invention comprises dyes of the formula <FORM:1021008/C4-C5/1> where X is hydrogen, chlorine, bromine or methyl, R is phenyl which is unsubstituted or substituted by non-ionogenic substituents and Hal is chlorine or bromine. The dyes are made by condensing, under ring closing conditions, a compound of the formula <FORM:1021008/C4-C5/2> where X, R and Hal are as above. Reference has been directed by the Comptroller to Specification 903,126.
