Abstract
Resinous composition for use in coating comprising a hexahydrophthalic acid or anhydride thereof whose acidic groups are capable of developing a resinous acid value and etherified aminoformaldehyde resin. This resinous composition is characterized by possessing all the advantages of oil-free polyester resin compositions such as good weather resistance mechanical properties in the coating, interlaminar adhesion and the like, and furthermore the composition inter alia, has excellent weather resistance because of its modification with saturated alicyclic acids and the curing properties are enhanced because of the control of the acidic groups which develops a resinous acid value. The invention also provides a coating composition, containing as a vehicle, the aforementioned resinous composition.
