    • The thermosetting resin composition of the present invention comprises: a polymer (A) containing at least one monomer selected from ethylenically unsaturated dicarboxylic anhydride, mono-ester thereof and mono-amide thereof as a repeating unit; and a polymer (B) containing an addition-polymerizable oxazoline and a hydroxyl group-containing monomer as repeating units, which can rapidly form a cured film excellent in acid rain resistance and other properties at relatively low temperature of 70.degree. to 140.degree. C. The further incorporation of a basic compound (C) and/or a compound (D) selected from the group consisting of a monohydric alcohol, a .beta.-diketone and an ortho-carboxylic ester to this thermosciting resin composition can give a remarkably improved storage stability to this resin composition as a one-part type composition. This thermosciting resin composition can exhibit excellent properties as a top clear coating for motor vehicle.

    • A coating composition of polymers of a vinyl oxazoline drying oil ester which esters are made by a process which reacts drying oil fatty acids with tris (hydroxy methyl) amino methane to form an intermediate which is further reacted at about 175.degree.-190.degree. C. with a formaldehyde/alcohol solution to form the vinyl oxazoline drying oil ester; the improvement used with this process is the use of at least 3 moles of formaldehyde to one mole of intermediate and about 1-5% by weight, based on the weight of the intermediate, of methanol and adding after the reaction with formaldehyde about 5-25% by weight, based on the weight of the ester solution, of an alcohol, a ketone or a mixture of an alcohol and a ketone; the coating composition are aqueous and contain sufficient ammonia or amine to provide a pH of about 7.5-9.5.
    • 乙烯基恶唑啉干燥油酯的聚合物的涂料组合物,其酯通过使干性油脂肪酸与三(羟基甲基)氨基甲烷反应形成中间体的方法制备,所述中间体在约175-190℃进一步反应。 用甲醛/醇溶液形成乙烯基恶唑啉干油酯; 使用该方法的改进是使用至少3摩尔甲醛至1摩尔中间体和约1-5重量%(基于中间体的甲醇重量),并在与甲醛反应后加入约5- 25重量%,基于酯溶液的重量,醇,酮或醇和酮的混合物; 涂料组合物是含水的并且含有足够的氨或胺以提供约7.5-9.5的pH。
