Water-resistant multi-stage polymers having an alkali-insoluble polymer and an alkali-soluble polymer are prepared by sequential emulsion polymerization of a monomer mixture having acid functionality in the alkali-soluble stage and, optionally, a polyfunctional compound, the alkali-insoluble polymer having, optionally, an amine functionality, such that the resulting polymer has an alkaliinsoluble polymer stage and an alkali-soluble polymer stage. Films prepared using the multi-stage composition and method of this invention are particularly useful in semi-transparent wood stain binders. |
