Abstract

The invention comprises dyestuffs of formula <FORM:0785672/IV (b)/1> where R is an alkyl group which are obtainable by coupling appropriate 2-hydroxy-3-naphthoic acid arylamides with diazotized 3-amino-4-alkoxy-1-benzoyl ureas. The dyestuffs are red pigments which may be used for dyeing fibres, lacquers and resins. In an example, dyestuffs are made in which R is a methyl or ethyl group.
