Toughened urethane acrylate compositions

A cured article comprising a composite, a coating, an adhesive, an ink, an encapsulation, or a casting prepared from a resin composition, the resin composition comprising:

• a urethane (meth)acrylate;
• a reactive diluent;
• and
• a urethane (meth)acrylate toughener comprising at least one additional polyol having a number average molecular weight Mn from 1,000 g/mol to 15,000 g/mol.

A method of preparing a resin composition, comprising:

• reacting a polyisocyanate, a polyol, and a compound containing both a nucleophilic group and a (meth)acrylate group to form urethane (meth)acrylate;
• and
• mixing a reactive diluent and a urethane (meth)acrylate toughener with the urethane (meth)acrylate to form the resin composition, wherein
• the urethane (meth)acrylate toughener comprises at least one additional polyol having a number average molecular weight Mn from 1,000 g/mol to 15,000 g/mol.
