    • The present invention is to provide a low solvent content type-coating composition by which the resultant coatings with good scuff resistance or water resistance as well as good chipping resistance are produced, while the content of an organic solvent to be used can be much reduced. The low solvent content type-coating composition comprises a polyester oligomer having a hydroxyl group in an amount of 2.0 to 10.0 moles/Kg-resin, a number average molecular weight (Mn) of 300 to 1500, a weight average molecular weight (Mw) of 300 to 3000, and a ratio of a weight average molecular weight/a number average molecular weight (Mw/Mn) of 1 to 2.0, an amount of a modifying lactone being 31 to 85%, and an aliphatic hydrocarbon group of C4-22 which is not derived from lactones. The present invention is also to provide a process for coating a low solvent content type-coating composition on, for example, a base coating composition by a wet-on-wet coating. The base coating composition comprises a vinyl oligomer having a hydroxyl group and/or a blocked hydroxyl group, a melamine resin containing 50 to 100% of an imino type or methylol type mononucleus melamine and a weak acidic curing catalyst.
    • 本发明提供一种低溶剂含量型涂料组合物,通过该组合物可以产生具有良好耐擦伤性或耐水性的所得涂层以及良好的抗碎裂性,同时可以大大降低所用有机溶剂的含量。 低溶剂含量型涂料组合物包含羟基数为2.0〜10.0摩尔/ Kg-树脂的聚酯低聚物,数均分子量(Mn)为300〜1500,重均分子量(Mw) 的比例为300〜3000,重均分子量/数均分子量(Mw / Mn)为1〜2.0,改性内酯的量为31〜85%,C4- 22,它不是从内酯衍生的。 本发明还提供了通过湿式湿式涂布在例如底涂层组合物上涂布低溶剂含量型涂料组合物的方法。 基础涂料组合物包含具有羟基和/或封端羟基的乙烯基低聚物,含有50-100%亚氨基型或羟甲基型单核三聚氰胺的三聚氰胺树脂和弱酸性固化催化剂。

    • A one-pack coating composition is disclosed. The composition comprises (A) an oligomer or polymer containing an acid anhydride group, a blocked hydroxyl group and an epoxy group as indispensable functional groups in the same or different molecules, (B) a heat-potential curing catalyst which comprises a complex of an organometallic compound and an electron-donating compound or an onium salt and which exhibits its activity upon heating, (C) an ultraviolet absorber comprising a triazine or oxalic anilide, and (D) a hindered amine light stabilizer having a piperidine ring of the following structure: wherein R represents R1—CO—, a C2 to C20 alkyl group or R1—O— (R1 being a C2 to C20 alkyl group), and R2, R3, R4 and R5 independently from each other represent a C1 to C3 alkyl group, or a phenolic antioxidant. A method for coating using this coating composition is also disclosed.
