摘要
Described herein is a pigment paste for use in an aqueous paint comprising a film-forming latex polymer, a pigment and a dispersant copolymer. Also described is the dispersant copolymer which serves the function of dispersing the pigment in the preparation of the paste and maintaining the dispersion in the paste and paint made therefrom. The dispersant copolymer is such that its complex salt formed with Zn++ and ammonia is water-soluble at a pH of 9.6. The dispersant is a copolymer of an alpha , beta -unsaturated monovinylidene carboxylic acid and at least one other ethylenically unsaturated monomer. The dispersant is particularly adapted to preparing paste for difficult-to-formulate paints such as paints with reactive pigments and paints requiring high levels of dispersant.
