Liquid paste for paper

Abstract

Problem: It is to provide a liquid glue for paper, which is able to meet more diverse usages and needs, by using ingredients and compositions different from conventional ones, and to especially provide a liquid glue that hardly causes wrinkles in paper sheets. Solution: In a preferred embodiment, the solid content (nonvolatile content) excluding water is 40 to 70% by weight; and the solid content part is substantially composed of a water-soluble modified polysaccharide and a low molecular weight saccharide; weight ratio of low molecular saccharide to modified polysaccharide (weight of low molecular saccharide÷weight of modified polysaccharide) is from 0.4 to 12; and viscosity (BL type viscometer, 6 rpm) of the liquid glue is 700 to 8000 mPa/s. In particularly preferred embodiments, the water-soluble modified polysaccharide is a hydroxyalkylated starch, other modified starch, or dextrin; and the low molecular weight saccharide is a monosaccharide or disaccharides, such as sucrose, fructose, glucose, xylose, maltose, trehalose or the like, xylitol, sorbitol or oligosaccharides.
