Cationic polysaccharides modified, for the adhesive compositions containing them and 1995 for the bonding of plane structures employing these compositions

摘要

The invention relates to a novel composition for sizing, internal or external, of plane structures, in particular of paper, cardboard or of films. & br / the composition for sizing according to the invention contains a cationic polysaccharide n - alcénylsuccinylé having undergone an additional modification of the anionic or nonionic. & br / said polysaccharide may be constituted, in particular, of a cationic starch - octenylsuccinylated n or n - dodécénylsuccinylé, cutback or not, and modified by esterification, etherification, sulphonation or crosslinking. & br / the composition for sizing according to the invention can advantageously be applied to the bonding of plane structures intended for printing and / or writing, including cases of papers and papers for impact-free printing, such as the ink jet printing.
