ABSTRACT:
Readily dispersible pigment concentrate compositions are disclosed which can be easily dispersed in water, solvents and oils. The pigment compositions comprise 5 to 75% by weight of organic or inorganic pigment, 15 to 70% by weight of a solvent or mixture of solvents miscible with water and 7 to 35% by weight of a dispersing agent or mixture thereof. The dispersing agent is an addition product of ethylene oxide and castor oil, or an addition product of ethylene oxide and para-nonylphenol or an addition product of ethylene oxide and a fatty alcohol and mixtures of such dispersing agents.
The pigment compositions can be incorporated into natural or synthetic resin compositions and, for example, are suited for leather-finishing compositions when mixed with proteinaceous or nitrocellulose film-forming materials.
