Abstract
A pigmented polymer composition containing colorant particles and polymer particles having phosphorus acid groups is provided. The polymer particles are prepared from the low pH polymerization of phosphorus acid monomer, or alternatively, are substantially free of water soluble polymer bearing phosphorus acid groups. A method for preparing colored coatings from the pigmented polymer composition is also provided. Colored coatings have improved color properties.
