<p>A paper coating composition having improved ink receptivity in multi-color printing which comprises (I) 100 parts by weight of a pigment, and (II) 1 to 30 parts by weight, as solids content, of a latex of a copolymer derived from 20 to 50% by weight of an aliphatic conjugated diolefin, 0.5 to 5% by weight of an ethylenically unsaturated acid monomer, 0.5 to 5% by weight of an ethylenically unsaturated amine monomer, and 10 to 74% by weight of a mono-olefinically unsaturated monomer, said latex containing not more than 1% by weight, based on the copolymer of an emulsifier, having a gel point within a pH range of 3.5 to 8.5 and being gellable during the drying of a paper coated with said composition, said composition having a higher pH than the gel point of the latex.</p> |
