Abstract
The liquid, uncrosslinked, UV-curable Michael addition resins and blends of the present invention exhibit performance properties that make them very effective coating materials and these properties can be modified greatly depending upon composition. Michael donors and acceptors can be constructed from Type I and/or Type II photoinitiators and can be included in the coating compositions disclosed to make UV-curable coatings with extraordinary photoreactivity and properties. Resins can be produced that show excellent adhesion to metals, plastics, wood, paper and glass. They exhibit wide ranges of hardness, toughness, flexibility, tensile strength, stain resistance, scratch resistance, impact resistance, solvent resistance, etc. Almost any desired coating performance parameter can be attained by proper selection of raw material building blocks.
