Abstract
An actinic energy ray curable composition useful as a paint or coating agent, especially for products where scratch resistance is desired, includes a particular composition that includes a urethane (meth)acrylate obtained by reacting to an organic isocyanate having a plurality of isocyanate groups in one molecule with a polycaprolactone-modified alkyl (meth)acrylate and a long-chain alcohol.
Claims9
An actinic energy ray-curable composition comprising a urethane (meth)acrylate obtained by reacting an organic isocyanate having a plurality of isocyanate groups in one molecule with a polycaprolactone-modified alkyl (meth)acrylate and a long-chain alcohol, wherein said urethane (meth)acrylate contains two or more urethane (meth)acrylates different from one another in the number of repetitions of a caprolactone unit per one residue of the polycaprolactone-modified alkyl (meth)acrylate, and wherein the long-chain alcohol is selected from the group consisting of tridecanol, myristyl alcohol, cetyl alcohol, stearyl alcohol, behenyl alcohol, and polyoxyethylene monostearate.
An actinic energy ray-curable composition comprising:
- a urethane (meth)acrylate obtained by reacting an organic isocyanate having a plurality of isocyanate groups in one molecule with two or more polycaprolactone-modified alkyl (meth)acrylates different from one another in the number of repetitions of a caprolactone unit per one molecule, wherein a maximum in difference in the number of repetitions of the caprolactone unit between two of the polycaprolactone-modified alkyl (meth)acrylates is between 4 and 9 inclusive;
- and
- a urethane (meth)acrylate obtained by reacting an organic isocyanate having a plurality of isocyanate groups in one molecule with a polycaprolactone-modified alkyl (meth)acrylate and a long-chain alcohol, wherein the long-chain alcohol is selected from the group consisting of tridecanol, myristyl alcohol, cetyl alcohol, stearyl alcohol, behenyl alcohol, and polyoxyethylene monostearate.
