ZUSAMMENSETZUNG ZUR PAPIERBEHANDLUNG

摘要

The suitability of paper for printing by so-called "colour digital presses" of the kind which use a liquid toner or ink is enhanced by the use of a treatment composition comprising an aluminate salt or a salt of a weak acid and a strong base in an amount such as to impart an alkaline surface pH value to the paper. The treatment composition preferably also contains starch or another surface agent, so that the treatment composition also functions as a surface sizing composition.
