Title:
THERMALLY REVERSIBLE THICKENING COMPOSITION
Document Type and Number:
Japanese Patent JP2779610
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain a thermally reversible thickening compsn. which rapidly forms a strong gel when heated and provides marked effects on improving the luster and printability when used for producing a coated paper by compounding an anionic resin latex with a cationic thickening compd. which reversibly changes from hydrophilic to hydrophobic at a certain temp.
SOLUTION: This compsn. comprises 99.99-70wt.% anionic resin latex and 0.01-30wt.% cationic thickening compd. Examples of the latex are a resin latex obtd. by using a radical-polymerizable anionic emulsifier and a styrene-butadiene resin latex obtd. by the emulsion polymn. using as the emulsifier a (meth) acrylate having anionic groups and a polyoxypropylene chain. The compd., exemplified as one having a content of polyoxyethylene group of 50wt.% or higher and at least one cationic group, has a mol.wt. per cationic group of 700-50,000.
