Abstract:
A multicolor dispersion comprising a protective composition and two or more colorant dispersions, wherein the protective composition comprises (1) an aqueous dispersion of polymer particles comprising from 89% to 99.45% by weight, based on the total dry weight of the protective composition, of polymer particles, wherein said aqueous dispersion of polymer particles further comprises from 0.33% to 2% by weight, based on the total dry weight of the polymer, of an anionic stabilizer monomer represented by the following Formula I, wherein R1 is a linkage group between R2 and a vinyl group, R2 is ethylene or propene or butylene, n is from 0 to 50, M is a counter salt of potassium, sodium, ammonium or lithium; wherein said aqueous dispersion of polymer particles further comprises from 0.33% to 5% by weight, based on the total dry weight of the polymer, of a non-reactive anionic surfactant having an ethylene oxide chain length of less than 11; and (2) from 0.5% to 10% by weight, based on the total dry weight of the protective composition, of a clay.
