MODIFIED CATIONIC POLYSACCHARIDES, BONDING COMPOSITIONS CONTAINING SAME, AND METHODS FOR BONDING FLAT STRUCTURES USING THE SAME

摘要

The invention relates to a new composition for the internal or external bonding of flat structures, in particular paper, cardboard or films. The bonding composition according to the invention contains a cationic polysaccharide. -Alkenylsuccinylated having undergone a further modification of anionic or nonionic nature. BR/ Said polysaccharide may especially consist of an n-octenylsuccinylated or n-dodecenylsuccinylated cationic starch, fluidized or not, and modified by esterification, etherification, sulfonation or crosslinking. BR/ The bonding composition according to the invention may advantageously be applied to the bonding of flat structures intended for printing and / or writing, including envelope papers and printing papers without such impact. than inkjet printing. / P
