Thickened paper coating composition

摘要

A coating composition, comprising an aqueous dispersion of a pigment such as clay and a binder such as a latex of a copolymer of styrene and butadiene thickened with a water-soluble copolymer of an alpha , beta -ethylenically unsaturated carboxylic acid such as acrylic acid, an ethylenically unsaturated carboxamide such as acrylamide and an ethylenically unsaturated monomer having limited solubility in water such as acrylonitrile, is effectively employed in coating paper and other cellulosic web materials.
