ABSTRACT:
Powder paint coatings of this invention are particularly suitable for ultraviolet curing and comprise specific spatial arrangements of ethylenically unsaturated polymers. The polymers contain pendant double bond unsaturation in combination with an epoxy adduct spaced on the polymer chain from a polyester adduct. The powder paint is free of cold flow and can be applied electrostatically or physically to metal substrates, moderately heated to obtain desired flow out, and then cross-linked or cured by ultraviolet irradiation.
