SURFACE SIZING AGENT FOR PAPERMAKING, COATING LIQUID CONTAINING THE SURFACE SIZING AGENT AND PAPER PROVIDED BY USING THE LIQUID

摘要

PROBLEM TO BE SOLVED: To improve a sizing performance of emulsion type surface sizing agent for papermaking.;SOLUTION: The emulsion type papermaking surface sizing agent is provided by adding a water-soluble aluminum-based compound (E) such as aluminum sulfate, aluminum chloride, basic aluminum sulfate, basic aluminum chloride, aluminum sulfate silicate and a polymer thereof to a polymer dispersion (D) obtained by polymerizing a vinyl monomer containing a hydrophobic monomer (A) in the presence of a cationic water-soluble polymer (B) and/or a cationic surfactant (C).;COPYRIGHT: (C)2010,JPO&INPIT
