Disazo pigments, processes for their manufacture and use
Abstract
Abstract WHEREIN R1 denotes an alkyl, alkoxyalkyl or cycloalkyl group containing 1 - 6 carbon atoms or an aralkyl, aryloxy or aryl group, R2 denotes the group Z-R1 or a hydrogen or halogen atom or a nitro, trifluoromethyl or nitrile group or an alkyl group containing 1 - 4 carbon atoms, R3 denotes a hydrogen or halogen atom or a trifluoromethyl group, Z denotes a sulphur or oxygen atom, X denotes a hydrogen or halogen atom, an alkyl or alkoxy group containing 1 - 4 carbon atoms or a nitro, nitrile, trifluoromethyl, carboxylic acid amide or carboxylic acid ester group and Y denotes a hydrogen or halogen atom, an alkyl or alkoxy group containing 1 - 4 carbon atoms or a nitro, nitrile, trifluoromethyl, carboxylic acid ester or carboxylic acid amide group. The pigments are insoluble and show excellent fastness to light and migration and can be used for pigmenting high molecular weight organic materials such as cellulose esters, polyamides and polyesters. New disazo pigments being qualified for pigmenting high molecular organic material and having the formula
