(57) [Summary] [Purpose] The surface of a coated paper, which has a high surface strength and good printability, does not impair the characteristics of PVA and has a high-speed coating property superior to conventional surface sizing agents. To provide a sizing agent. [Constitution] A surface sizing agent for paper, which contains polyvinyl alcohol resin and polyether as essential components. [Effect] A coated paper having high surface strength and good printability can be obtained. Furthermore, high-speed coating properties compared to conventional surface sizing agents, especially even when high-speed coating with a gate roll coater, there is little scattering of the coating liquid, so stable production of coated paper with good printability is possible. It will be possible. |
