COMPOSITION BASED ON HOLLOW POLYMERS Russian patent published in 2020 - IPC C09D7/65 C09D5/02 C09D151/00 

FIELD: chemistry.

SUBSTANCE: invention relates to an aqueous dispersion suitable for use in coatings and inks. Aqueous dispersion contains 40–98.9 wt % of water, 1–40 wt % of hollow polymer particles and 0.1–20 wt % of one or more polyatomic alcohols per weight of the aqueous dispersion. Hollow polymer particles contain 0.01–20 wt % of polymerised links of one or more polyvinyl monomers per weight of hollow polymer particles, wherein said hollow polymer particles are dispersed in water. Hollow polymer particles contain a core polymer and a cladding polymer, wherein the number of polymerised units of the nonionic monomer in the cladding polymer is 90–100 wt % with respect to the weight of the cladding polymer.

EFFECT: providing an aqueous composition which after drying forms a dry composition which can be added to the composition of the solvent-based composition without a strong agglomeration tendency.
