Abstract

1318574 Disazo pigments CIBA-GEIGY AG 8 July 1970 [8 July 1969] 33179/70 Heading C4P New disazo pigments of formula wherein R 1 is a phenyl residue containing in one ortho-position to -N=N- a H atom or an alkyl group and in the other ortho-position a H atom, R 2 is a naphthalene residue in which -N=N-, -OH and -CO- are in the 1,2,3- positions and which is free from nitro groups, R 3 is a H atom, or an alkyl, cycloalkyl or aryl group, R 4 is a H atom or an alkyl group, R 5 is a benzene or naphthalene residue, X is a H or halogen atom or an alkyl or OCH 3 group and Y is a H or halogen atom or OCH 3 are prepared by (1) condensing 2 mols of an appropriate monoazo dye carboxylic acid halide with 1 mol of a phenylene or naphthylene diamine or (2) coupling 2 mols of a diazotized amino-benzamide with an appropriate dinaphthol. The pigments are used to colour macromolecular materials, in particular polyvinyl chloride in red shades. Reference has been directed by the Comptroller to Specification 942,431.
