Abstract
Finely-dispersed pastes of organic or inorganic pigments are made by kneading the pigment with at least 10 per cent by weight of a polyglycol ether, the proportions being such that the mixture has an initial viscosity of 2000 centipoises or over. Preferably, 50-90 per cent of the ether is employed, and the initial viscosity is over 106 centipoises. Water or other diluting agent may be those disclosed in German Specifications 605,973, 667,744, 694,178, 679,710, 824,949 and 806,671, Austrian Specification 160,871 and Specification 690,355, [Group IV (a)]. The pastes may be used in the dyeing of polyacrylonitrile, viscose, and copper rayon, for colouring lacquers and resins, pigment printing, colouring paper pulp, and for wallpaper colours. In examples: (1) the condensation product from hydroxydiphenyl, benzyl chloride, and ethylene oxide (Example 1 of German Specification 824,949) is kneaded with the following: (a) the dyestuff 2.5 - dichloro - aniline --> 21.31 - hydroxynaphthoylamino-benzene, (b) the dyestuff 4-chlor - 2 - toluidine --> 1 - phenyl - 3 - methyl-5-pyrazolone, (c) copper phthalocyanine, (d) red iron oxide; (2) the disazo dye from diazotized o - aminodiphenyl and 3.31 - dimethyl - 4.41-diaceto - acetylamino - diphenyl is kneaded with isooctylphenyl polyglycol ether according to Example 1 of Austrian Specification 160,871.ALSO:Finely-dispersed pastes of organic or inorganic pigments are made by kneading the pigment with at least 10 per cent by weight of a polyglycol ether, the proportions being such that the mixture has an initial viscosity of 2000 centipoises or over. Preferably 50-90 per cent of the ether is employed, and the initial viscosity is over 106 centipoises. Water or other diluting agent may be added.

The pastes may be used in the dyeing of polyacrylonitrile, viscose, and copper rayon, for colouring lacquers and resins, pigment printing, colouring paper pulp, and for wallpaper colours. In examples, the condensation product from hydroxy-diphenyl, benzyl chloride, and ethylene oxide (Example 1 of German Specification 824,949) is kneaded with red iron oxide.
