AGENT FOR MAKING RECORDING PAPER WATERPROOF

Title:

AGENT FOR MAKING RECORDING PAPER WATERPROOF

Document Type and Number:

Japanese Patent JP3509381

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To obtain an agent which can make paper water-proof and prevent paper from ink-staining by polymerizing the monomers constituting polymerizable monomers containing a quaternary nitrogen atom in the presence of a polymerization initiator bearing an azo group.
SOLUTION: A polymerizable compound of formula I (R1 and R2 are each alkyl; X is a halogen) such as dialkyldiallylammonium halide and, preferably, a (meth)acrylic amide are polymerized in an aqueous medium using a polymerization initiator having one or more azo groups represented by formula II, for example, 2,2'-azobis(2-amdinopropane) to give the objective water-proofing agent. A paper base material is coated with the coating solution containing the agent to give the objective recording paper.
