Claims3
A UV curable coating composition, comprising:
- a first aliphatic urethane acrylate resin that is a reaction product of a compound represented by formula I below with an alcohol:
- wherein R1, R2, and R3 of formula I are the same or different, and each comprise linear or branched, C4-C20 (cyclo) alkyl groups, wherein X is the same or different and comprises isocyanate groups and wherein R1, R2, and R3 of formula I are attached to a nitrogen atom;
- and
- a second aliphatic urethane acrylate resin formed by the reaction of a multifunctional acrylate with an aliphatic urethane based on a polymer of alkyl carbomonocycle diisocyanate, wherein the first aliphatic urethane acrylate resin and the second aliphatic urethane acrylate resin comprise a weight ratio of 1:3 to 3:1.
