Abstract
A paper mat is made from an aqueous slurry or dispersion of kraft wood pulp, a large amount of finely divided inorganic pigments and as a binder an anionic latex of a copolymer of at least one conjugated diene monomer, at least one vinyl substituted aromatic monomer, at least one acrylic-type monomer and at least one monomer having a vinyl group and an activatable methyl, ethyl, propyl or butyl ester group. The mat of this invention exhibits improved properties over mats made from other latex binders.
