Abstract:
A thermosetting organic solvent coating composition capable of forming a cured coating film having a TUKON hardness at 20.degree. C. of 15 or more when a coating of the composition is applied on a glass plate so as to give a film having a thickness of 30 .mu.m as cured, and the resulting film is heat-cured at 140.degree. C. for 30 minutes; and a minimum value of dynamic modulus E' at a frequency of 110 Hz in the temperature range of 150-200.degree. C., of 1.times.10.sup.9 dyn/cm.sup.2 or more, which comprises:(A) a compound containing at least 2 alicyclic epoxy groups in the molecule and having a number-average molecular weight of smaller than 2,000,(B) an epoxy group-containing acrylic resin having a number-average molecular weight of 2,000-50,000, a hydroxyl value of 10-150 mg KOH/g and an epoxy equivalent of 220 or less,(C) a thermoinitiated cationic polymerization catalyst, and(D) a fluorine-containing resin,wherein the molar ratio of the epoxy groups of the component (A) to the epoxy groups of the component (B) is 1:1 to 1:0.05.
