Abstract

Quinophthalene dyes, free from sulphonic acid groups, of the formula where R1 and R2 are H, acylamine, lower alkoxy or halogen, one of R1 and R2 being acylamine, R3 is H, halogen or lower alkoxy, X is a substituent and n=0-3, are prepared by reacting an acylamino-phthalic acid of the formula or an anhydride of such an acid, with a 3-hydroxy-quinaldine of the formula where Y is H or COOH which is split off during the reaction. The dyes are used on hydrophobic synthetic fibres such as polyesters, cellulose triacetate, polyalkenes, polyamides and polyurethanes.
