The paper which the size medicine, and the said size medicine which are obtained with production manner and the said manner of the cationicity surface size medicine the coating is done

摘要

P To provide a cationic surface sizing agent giving superior sizing properties compared with conventional cationic surface sizing agents, in which the stability of the product in a coating liquid and the redissolution properties of a dried resin are improved, the generation of troubles due to adhesion of a dried film in a manufacturing process or in use can be controlled, further in off-set printing and greasing hardly occurs ON a printing face of a newspaper and the ink adhesion capacity is also superior. PSOLUTION: After at least one kind of a hydrophobic monomer is polymerized in the presence of (A) a copolymer of a tertiary amino group containing monomer and a (meth) acrylate ester type monomer and a styrene type monomer, and a surfactant and the ter-amino group in the copolymer (A) is converted into a quarternary ammonium salt.
