Abstract
1420093 Quinophthalone dyes IMPERIAL CHEMICAL INDUSTRIES Ltd 22 May 1973 [3 July 1972] 31047/72 Heading C4P Quinophthalone dyes for textiles are of formula (in which Y is H, halogen, alkyl or phenyl; X is O, NH or N-alkyl; R is optionally substituted alkyl or aryl). The dyes are prepared by conventional condensation reaction, by reacting the corresponding dicarboxylic anhydride with RXH or by ring opening of the corresponding phthalimide. The preparation of the following intermediates is alsodescribed: 41- and 61- bromo - 3<SP>1</SP> - hydroxy - quinophthalone - 5,6- dicarboxylic acid anhydrides; the N-(2<SP>11</SP>-ethyln-hexyl) - phthalimide and N - (γ - methoxypropyl) - phthalimide of 5,6-dicarboxy-3<SP>1</SP>- hydroxyquinophthalone and 6<SP>1</SP>-methyl-and 6<SP>1</SP>- chloro-3<SP>1</SP>-hydroxy - quinophthalone - 5,6 - dicarboxylic acid anhydrides.
