Latest Patents

One of Ohtaka's latest patents is a liquid curable urethane (meth)acrylate containing resin composition. This composition features a urethane bond at a concentration of 2.0.times.10.sup.-3 mole/gm or more and includes: (a) a urethane (meth)acrylate with at least three cyclic structures in the molecule; (b) a polymerizable mono-functional vinyl monomer whose homopolymer has a glass transition point of 50.degree. C. or more; and (c) a polymerization initiator. The resulting liquid curable resin composition possesses a high Young's modulus, exhibits minimal contraction stress, and demonstrates high tenacity along with good curing characteristics. These superior properties make it an ideal coating material for optical fibers. Additionally, the resin composition's high Young's modulus and tenacity render it useful as a protective coating for metals, plastics, wood, ceramics, glass, and more.
