    Abstract: Azo dyes. Cpds. of formula (I): (where A is anthraquinone, benzanthrone, anthrapyridone, anthrapyrimidine, pyrazolanthrone or thiazolanthrone derivs.; X is S or a -NH- bridge, and Y is a gp. which unites with the residue: to give a 5- or 6-membered ring which may itself contain (substd.) fused 5- or 6-membered rings; the benzene ring R may contain substits.). Preferably, cpds. (II): (where Z is orthophenylene, opt. contg. Me, MeO, carbonamide or sulphonamide gps., 1,2-naphthylene or one of the gps. -CH2-CH2-, -CH2-CH2CH2-, R1 is phenyl, benzoylamino or dimethylamino; R2 is H, Cl or OH; the ring E may contain Cl, benzoylamino or carboxylic anilide gps.). Used as pigment dyes, in print or varnish or for dyeing macromolecular materials, and have good colour fastness esp. towards solvents and light.

    Abstract: Tricyclic isquinolone derivs. Title cpds. of formula (I): (where R1 is H, halogen, an aliphatic, cycloaliphatic, aromatic or araliphatic residue or a group-N(R3)2 in which each R3 is H or an aliphatic, araliphatic or aromatic residue and R2 is an aliphatic, cycloaliphatic or araliphatic residue), which are intermediates for dyes and pesticides, are prepd. by reacting an o-(cyano-methyl or carbamoylmethyl)-R1-subst. phthalic acid with H2N-R2-NH2 at 100-200 degrees C. Products in which R is H, 1-6C alkyl, 5-8C cycloalkyl, 7-12C aralkyl, phenyl Cl or -N(R3)2 in which each R3 is H, 1-4C alkyl, 2-5C aliphatic acyl, benzyl, benzoyl or phenyl and R2 is 1-6C alkylene, 5-8C cycloalkylene or 7-12C aralkylene are claimed per se.
