Prior Art and Complaints of Arrogance Conventionally, binders for pigment coatings include casein, starch, common polyvinylfluoro-1v (hereinafter abbreviated as PVA), and styrene-butadiene latex. latexes are used. Of these, ordinary unmodified PVA has better performance than other binders in terms of surface hardening of crushed paper, printability, etc., but on the other hand, In particular, at high shear rates, which is a problem in actual coaters, the viscosity tends to increase, often causing problems in coating properties. In addition, regarding the surface strength, when using water such as offset printing, Juhyo 5! ! It had the disadvantage of being low in strength.

が得られることを見出し本発明を完成するに到った。Means for Solving the C1 Problems - In order to solve these problems, the authors conducted a more extensive study based on the PVA chemistry father's notes, and combined a large number of modified PVAs obtained. As a result of performing pigment coating using it as a binder and evaluating its use as a binder,
When modified polyvinyl alcohol containing 1 to 10 mo/l/% of α-olefin units is used, the viscosity is relatively low even under both shear im degrees, resulting in excellent coating properties and excellent water-resistant surface strength. They also discovered that a coated paper with excellent printability could be obtained and completed the present invention.
