Abstract:
Disclosed is coated paper having a coating structure in which styrene-butadiene latex distribution of a paper coating layer is controlled in order to reduce fold cracking of the coated paper and a method for manufacturing the same. The coated paper in which different types of latexes are separately applied to two coating layers exhibits considerably improved stiffness and reduced fold crack, as compared to the existing coated paper.
