Abstract
A polyurethane acrylate resin is formed by reacting 6 to 30 parts by equivalent of (A) imine diol; 6 to 30 parts by equivalent of (B) polyester diol, polycarbonate diol, or a combination thereof; 10 to 30 parts by equivalent of (C) hydroxyalkyl acrylate, hydroxyalkyl methacrylate, or a combination thereof; and 50 parts by equivalent of (D) diisocyanate, in which (A) imine diol has a chemical structure of
Claims10
A polyurethane acrylate resin, being formed by reacting
- 6 to 30 parts by equivalent of (A) imine diol;
- 6 to 30 parts by equivalent of (B) polyester diol, polycarbonate diol, or a combination thereof;
- 10 to 30 parts by equivalent of (C) hydroxyalkyl acrylate, hydroxyalkyl methacrylate, or a combination thereof;
- and
- 50 parts by equivalent of (D) diisocyanate,
- wherein (A) imine diol has a chemical structure of
- wherein R1 is
- linear —(CnH2n)— or branched —(CnH2n)—, wherein m=2 to 40, n=2 to 16, and each of R3 is independently C1-6 alkyl group;
- and
- each of R2 is independently substituted or unsubstituted C2-24 alkylene group or C3-24 cycloalkylene group, or substituted or unsubstituted C6-24 monocyclic or bicyclic arylene group.
