Abstract:
1. Coated paper coated with a paper coating solution comprising a pigment, an auxiliary pigment and a styrene-butadiene latex, wherein the coated paper has a double-layer coating structure in which a pre-coating layer and a top coating layer comprising styrene-butadiene latexes having different particle sizes and different glass transition temperatures are sequentially formed on a base paper, wherein the double-layer coating structure includes a first coating layer as the pre-coating layer and a second coating layer as the top coating layer, wherein a thickness ratio of the first coating layer to the second coating layer is 0.1 to 1.0 and a total thickness of the first coating layer and the second coating layer is 20 to 60 μm, wherein the first coating layer is formed using a coating solution comprising a latex having a particle size of 70 to 120 nm and a glass transition temperature of 10 to 30° C., and wherein the second coating layer is formed using a coating solution comprising a latex having a particle size of 120 to 200 nm and a glass transition temperature of −30 to 0° C.
