Dry, water-dispersible pigment compositions |
摘要 |
Dry pigment compositions which are easily dispersed in aqueous systems are described. The compositions contain 55 to 80% of a pigment and 45 to 20% of a nonionic material comprising, by weight of the pigment, 15 to 45% of a nonionic dispersing agent and 10 to about 67% of a water-dispersible, at least partially hydrolyzed polymer of vinyl acetate or a polymer of an N-vinyl pyrrolidone.
