Abstract:
The present invention relates to a latex composition comprising a) an opaque polymer having a pigment volume concentration of from 18 to 28; b) fully or partially polymer encapsulated TiO2 particles having a pigment volume concentration of from 8 to 18; c) an extender having a pigment volume concentration of from 0 to 10; d) a binder; e) a thickener; and f) water. Notwithstanding the surprisingly high pigment volume concentration of opaque polymer, the composition—upon application to a substrate—gives a coating with a gloss or semi-gloss finish, excellent hiding, and acceptable burnish resistance.
