INSOLUBILIZERS FOR BINDERS IN PAPER COATING COMPOSITIONS |
摘要 |
This invention relates generally to insolubilizers for use with binders in paper coating compositions. There is provided a process for preparing both an insolubilizer and paper coating composition containing the insolubilizer and a binder which, when applied onto paper products, significantly enhances their wet-rub resistance. The insolubilizer is prepared by: a) forming a glyoxal-urea adduct by reacting from about 1.0 to about 4.0 moles of glyoxal with about 1.0 mole of urea, at an elevated temperature; b) cooling the glyoxal-urea adduct to room temperature; c) adding from about 0.5 to about 2.0 moles of free glyoxal to the glyoxal-urea adduct to form an oligomer; and d) adjusting the pH of the oligomer to from about 5 to about 7.
