Paper coating composition

摘要

A paper coating composition which comprises: (I) a pigment; (II) an aqueous binder; (III) a mixture or a reaction product of a water-soluble resin (A) which can be obtained by reacting, at least, (a) an alkylenediamine or a polyalkylenepolyamine, (b) an urea compound and (c) a compound selected from aldehydes, epihalohydrins and alpha , gamma -dihalo- beta -hydrins; and an amide compound (B-1) which can be obtained by reacting (x) an alpha , beta -unsaturated carboxylic acid compound and (y) a primary or secondary amino compound, or an aminonitrile compound (B-2) which can be obtained by reacting (z) an alpha , beta -unsaturated nitryl compound and (y) a primary or secondary amino compound; wherein the water-soluble resin of the component (A) may be further allowed to react with a dibasic carboxylic compound, an alicyclic amine and/or an alicyclic epoxy compound in addition to the above three ingredients; and paper coated by using the above composition is especially excellent in ink receptivity and water resistance.
