UNDERCOATING LIQUID FOR WATER-REPELLING AGENT, WATER-REPELLING PAPER HAVING COATING LAYER THEREOF, AND METHOD FOR PRODUCING THIS WATER-REPELLING PAPER

摘要

PROBLEM TO BE SOLVED: To provide water-repelling paper free of water-repelling agent sink with high water repellency, and to provide an undercoating liquid for a water-repelling agent for the water-repelling paper.;SOLUTION: The undercoating liquid for a water-repelling agent contains compound obtained by reaction between (A) a cationic copolymer synthesized from a styrene-based monomer and an amino group-bearing vinyl monomer as the essential monomer components and (B) a monocarboxylic acid as an acid component. The compound is at least one selected from the group consisting of a polyamide, an epihalohydrin-modified product thereof, and an alkyl ketene dimer.;COPYRIGHT: (C)2008,JPO&INPIT
