    • An agent for forming a surface-protecting layer on a coated paper, which comprises an aqueous solution of an alkali metal salt, ammonium salt or amine salt of a graft copolymer and an epoxy group-containing cross-linking agent incorporated in the aqueous solution, said graft copolymer comprising (A) 10 to 60% by weight of a polyvinyl alcohol polymer selected from the group consisting of partially saponified polyvinyl alcohols, polyvinyl alcohols containing copolymerized units of a vinyl monomer having carboxyl group, and polyvinyl alcohol having the recurring vinyl alcohol units esterified with a higher fatty acid, (B) 20 to 70% by weight of acrylamide or methacrylamide, (C) 5 to 30% by weight of at least one member selected from the group consisting of acrylonitrile, methacrylonitrile, lower alkyl esters of acrylic acid and methacrylic acid and hydroxyl lower alkyl esters of acrylic acid and methacrylic acid, and (D) 5 to 20% by weight of at least one vinyl monomer containing a carboxyl group.
    • 在涂布纸上形成表面保护层的试剂,其包含接合共聚物的碱金属盐,铵盐或胺盐的水溶液和在该水溶液中引入的含环氧基的交联剂, 所述接枝共聚物包含(A)10至60重量%的选自部分皂化聚乙烯醇的聚乙烯醇聚合物,含有具有羧基的乙烯基单体的共聚单元的聚乙烯醇和具有重复乙烯醇的聚乙烯醇 用高级脂肪酸酯化的单元,(B)20至70重量%的丙烯酰胺或甲基丙烯酰胺,(C)5-30重量%的至少一种选自丙烯腈,甲基丙烯腈,低级烷基酯, 丙烯酸和甲基丙烯酸和丙烯酸和甲基丙烯酸的羟基低级烷基酯,和(D)5至20重量%的至少一种含有羧基的乙烯基单体 基团。
