Abstract of the Disclosure Mineral coating compositions for coating papers, the binder of which comprises a negatively-charged latex or aqueous dispersion of an emulsion polymer, with or without an amylaceous binder, as the major portion thereof, and a relatively small amount of a water-soluble addition polymer having polymerized therein from 20% to 100%, pre-ferably at least 40%, by weight of a monoethylenically unsaturated monomer having a primary, secondary, or tert-iary amine group, such as an aminoalkyl acrylate, meth-acrylate, vinyl ether or vinyl sulfide, an N-aminoalkyl-(meth)acrylamide, an N-acryloxyalkyl-oxazolidine or an N-acryloxyalkyl-tetrahydro-1,3-oxazine. |
