1. The condensates and epoxidized products have exceptionally high fluorescence as well as good ultraviolet absorbance.

2. The invention is a process for epoxidizing an olefin with hydrogen and oxygen in a solvent comprising acetonitrile in the presence of an quinone-acid salt and a catalyst comprising a titanium zeolite and a noble metal.

3. The actinic-energy-ray-curable ink composition for ink-jet recording comprises (b) a photopolymerization initiator, (d) 40-75 mass% cyclic monofunctional (meth)acrylate, (e) 5-20 mass% hydroxylated (meth)acrylate, and (c) 3-10 mass% epoxidized silane coupling agent, and is for use in recording on glass surfaces.
