Abstract
In a thermosetting coating composition comprising at least one thermosetting resin selected from aminoalkyd resins and aminoacrylic resins as a main ingredient of a vehicle, the improvement wherein the composition contains 100 parts by weight of the thermosetting resin and 5 to 50 parts by weight of a cyclopentadiene-derived hydrocarbon resin having a softening point of 50.degree. to 160.degree. C. and obtained by heat polymerizing a mixture of 85 to 55% by weight of a cyclopentadiene-type monomer with 15 to 45% by weight of a polar monolefinic monomer copolymerizable therewith. The compositions have improved flexibility, impact strength and adhesion and are useful as vehicles for thermosetting oil-base paints.
