    • This invention is directed to a process for preparing grafted organic polyester of phosphoric acid, incorporated into water-borne coating compositions, reducing remarkably the tendency of aluminum flake pigments to react with the aqueous medium of the compositions, resulting in generation of hydrogen. This can be obtained by grafting the reaction product from the reaction of an orthophosphorus derivative with a compound which contains in the molecule an epoxide group and aromatic or alicyclic group, to a pre-polymer having isocyanate group as an end group and an ethyleneoxide group. The grafted organic polyester of phosphor acid has excellent dispersity with pigments and results in satisfactory adhesion with resin as a binder because it prevents pigments from contacting with water during water dispersing.
    • 本发明涉及一种制备接枝的磷酸有机聚酯的方法,其结合到水性涂料组合物中,显着降低铝片状颜料与组合物的水性介质反应的趋势,从而产生氢气。 这可以通过将正磷衍生物与分子中含有环氧基和芳族或脂环族基团的化合物反应的反应产物接枝到具有异氰酸酯基的预聚物作为端基和环氧乙烷基团来获得。 磷酸酯的接枝有机聚酯与颜料的分散性优异,并且与树脂作为粘合剂具有良好的粘附性,因为它防止颜料在水分散期间与水接触。

    • The present invention relates to a process for production of a water-dispersion of polyurethane resin by an organic acid-oxirane ring opening reaction and to an water-borne paint composition containing the resin made thereby, wherein said a water-dispersion of polyurethane resin is obtained by reacting polyisocyanate and the following polyols: a) A polyol grafted with a long chain alkyl group obtained by organic acid-oxirane ring opening reaction; b) Neutralized dimethyl alkyl acid of 0.1 to 100 milliequivalents and polyethylene glycol of 10 to 2,000 number average molecular weight as functional groups for water-dispersion of synthesized resin. c) Polyol having at least one or more hydroxyl groups on termini and a number average molecular weight of 10 to 2,000. The water-borne paint composition containing a water-dispersion of polyurethane resin, of the present invention, has such advantages as realizing a coating layer of rich gloss, excellence in anti-water and anti-chipping resistance, good storability and effective sprayability.
