SURFACE TREATMENT AGENT FOR PAPER

摘要

PROBLEM TO BE SOLVED: To provide a surface treatment agent for paper such as coating base paper, and a lightweight coated paper having high glossiness and obtained by applying the surface treatment agent to a paper.

SOLUTION: The surface treatment agent for paper contains a cationic group-containing copolymer obtained by polymerizing a specific vinyl monomer and a specific cationic group-containing vinyl monomer at a specific molar ratio or polymerizing the specific vinyl monomer with the specific cationic group-containing vinyl monomer and a crosslinkable vinyl monomer at a specific molar ratio. The coated paper is constituted by applying a coating liquid containing a pigment and an adhesive as main ingredients to a base paper coated with the cationic group-containing copolymer.
