Abstract (en)

[origin: WO9906463A2] Composition suitable for free radical, radiation curable coating comprising at least one polyester having unsaturated backbone and at least one compound having one to six propenyl ether groups, and optionally, a free radical photoinitiator. The equivalent ratio of propenyl ether groups to maleimide, maleate and/or fumarate groups in the polyester is preferably about 5:1 to 1:5. The process for curing the composition includes exposing it to ionizing radiation and/or ultraviolet light. The resultant cured coatings and coated articles are similar in performance to their vinyl ether analogues, but the propenyl ethers are easier to prepare than the vinyl ether analogues.
