  • Liquid starch dispersions for coated paper and paperboard
    Publication number: 20030173045
    Abstract: The present invention relates to a liquid starch dispersion for paper coating where the dispersion has 5 to 50 percent by weight of starch, and the starch contains from 20 to 100 percent by weight of at least one cationic starch. The liquid starch composition is characterized in that a 25 percent by weight starch solids dispersion has a 25° C. viscosity of from 500 to 2500 cps both initially, and also upon storage at room temperature for 90 days. The dispersion preferably contains a blend of cationic starch and ASA starch. The liquid starch dispersion is useful in paper and paperboard coating processes, as a rheology modifier, a structurant, and/or a binder, all at the same time. The liquid starch dispersion provides good coating holdout, gloss, and stiffness properties. The cationic nature of the starch coating improves printability with anionic inks, and makes the coatings useful for ink-jet and photographic papers.
