PURPOSE: A paper coating composition with blending latex is provided to ensure excellent an ink drying speed while not degrading adhesive force in paper coating and to reduce ink drying time. CONSTITUTION: A paper coating composition with blending latex comprises 60~95 weight% styrene-butadiene latex and 5~40 weight% blending latex. The glass transition temperature of the styrene-butadiene latex is -20 to 25 °C The particle diameter of the styrene-butadiene latex is 110~180 nm. The styrene-butadiene latex includes 20~45 weight% 1,3-butadiene, 45~78 weight% styrene, 1~15 weight% ethylenically unsaturated monomer, and 0~10 weight vinyl cyanide monomer. |
