Abstract

The invention comprises anthrones having a five-membered heterocyclic ring fused on in 1.9-position, and an aliphatic acylamino group in 5- or 8-position, containing the residue of an aliphatic monocarboxylic acid. They are made by acylation of the 5- or 8-amino bodies. The products dye or print cellulose esters, nylon, or superpolyurethanes. In examples 5- or 8-aminoisothiazoleanthrone-, 5-amino-1.9-pyrazoleanthrone methylated at either of the nitrogen atoms and 5-amino -1.9-thiophene-anthrone are heated in chlorbenzene in presence of dimethylaniline with propionyl chloride, butyryl chloride, isobutyl chloride, valeryl chloride or acetyl chloride or mixtures thereof. A dyeing example dyes cellulose acetate with a sulphite cellulose liquor dispersion of one of the products which had been acid-pasted. Other anthrones specified are 1:9 -(N)-isoxazole-anthrone, 1.9 - (N) - pyrrole - an - throne and anhydro-anthraquinone 1- sulphonic acid amide. Other acylating agents specified introduce the radical of caproic, caprylic, lauric, palmitic, stearic, or oleic acids.
