    摘要: Iminoisoindolinone dyestuffs of the formula

    WHEREIN R denotes an aromatic radical, R1 denotes a H or chlorine atom, an alkyl, alkoxy, hydroxyalkoxy or alkoxyalkoxy group containing 1 to 4 carbon atoms, or a phenoxy, phenalkoxy, phenalkoxyalkoxy or phenoxyalkoxy group and the X denote halogen atoms, are provided. The dyestuffs are valuable pigments which may be used for pigmenting high molecular organic materials such as cellulose, ethers, polyamides or polyesters. The pigments possess high fastness properties, especially excellent fastness to light, migration and weathering.

    摘要: Production of water-soluble cationic dyes by reaction of 1-lower alkyl- Delta 2, -indolineacetaldehydes, primary and secondary aromatic amines and orthophosphoric acid in an inert watermiscible organic solvent. This improved process provides a substantially quantitative product yield while avoiding addition of dye-precipitating agent to the reaction mass.
