Title:
LIQUID PASTE FOR PAPER
Document Type and Number:
WIPO Patent Application WO/2023/157946
Kind Code:
A1
Abstract:
Provided is a liquid paste that is for paper and that can be applied to further various applications and needs by having a compositional makeup and components different from those in conventional products. The liquid paste is particularly a liquid paste that is unlikely to generate wrinkles. In a preferable embodiment of the liquid paste according to the present invention, the contained amount of solid content (nonvolatile matter) excluding water is 40-70 wt%. The solid content substantially comprises a water-soluble modified polysaccharide and a low-molecular-weight sugar (molecular weight of 1000 or less). The weight ratio (weight of low-molecular-weight sugar / weight of modified polysaccharide) of the low-molecular-weight sugar with respect to the modified polysaccharide is 0.4-12. The liquid paste has a viscosity (BL-type viscometer, 6 rpm) of 700-8000 mPa/s. In a particularly preferable embodiment of the liquid paste according to the present invention, the water-soluble modified polysaccharide is hydroxyalkylated starch, other processed starch, or dextrin, and the low-molecular-weight sugar is a monosaccharide or a disaccharide such as sucrose, fructose, glucose, xylose, maltose, and trehalose, or an oligosaccharide such as xylitol and sorbitol.
