Abstract:
A paper containing homogeneously dispersed therein a cationic polysaccharide derivative having at least two cationic moieties bonded to each derivatized saccharide monomer, said derivative having been prepared by reaching a substantially non-crosslinked polycationic reagent having a single polysaccharide reactive group and at least two cationic groups, whereby the derivative is water dispersible, wherein the polycationic reagent is a polyamine having the structure:wherein R.sup.1, R.sup.3, R.sup.4 and R.sup.5 are identical or different and represent a C.sub.1 -C.sub.6 alkyl group or a C.sub.6 aryl group or a C.sub.6 -C.sub.12 alkaryl group; R.sup.2 are a C.sub.2 -C.sub.6 alkylene or alkylene ether or a C.sub.6 arylene or a C.sub.6 -C.sub.12 alkarylene group; R.sup.6, R.sup.7, R.sup.8 and R.sup.9 is independently, hydrogen or a C.sub.1 -C.sub.6 alkyl or a C.sub.6 -C.sub.12 alkaryl group; Z is a polysaccharide reactive group; and A is an anion.
