Abstract
A copolymer latex comprising 25 to 45 percent by weight of a conjugated diolefinic monomer, 3 to 40 percent by weight of an alkyl ester of unsaturated carboxylic acid, 1 to 5 percent by weight of a hydroxyalkyl-containing unsaturated monomer, 0.5 to 4 percent by weight of an unsaturated carboxylic acid monomer and the remaining percent of an alkenyl aromatic monomer, and a pigmented paper coating composition, which can give a coated paper having excellent properties, such as water resistance, 'transferability of multicolor offset printing ink' and blister resistance in case of web offset printing.
