Abstract

The pigment compositions of the parent Specification are made by heating with an organic solvent of boiling point above 100 DEG C. an aqueous paste containing two or more finely divided linear quinacridones of the formula <FORM:0955854/C3/1> where the rings X and Y may be substituted by halogen atoms, methyl groups or alkoxy groups of not more than 5 carbon atoms. A large number of organic solvents is specified including alcohols, ethers, esters, lactones, ketones, hydrocarbons, phenols, amines, amides, carboxylic acids, nitriles, sulphoxides and sulphones. Examples are given.
