Latest Patents

One of his latest patents is a sheet-form photocurable material. This material comprises a polymerizable unsaturated monomer, a polymer that is either polymethyl methacrylate or a high-molecular polymer consisting mainly of methyl methacrylate units, a photocuring agent, and a fibrous reinforcement. It is designed to be excellent in productivity, handleability, and photocurability. This photocurable sheet-form material is particularly useful for producing layered moldings and forming backup layers for molded articles, serving as a replacement protective material for pipes, covering materials, lining materials, and fixing materials.

Another significant patent is for a photocurable resin compound and method of curing the same. This sheet-like photocurable resin compound can secure or control a sufficient application time outdoors when irradiated with natural light, while also suppressing the volatilization of a styrene monomer. The compound includes a photocurable resin containing at least one unsaturated resin, a photopolymerization initiator that is not activated by light with a wavelength of 420 nm or above, and a thickener containing a thermoplastic resin powder. Additionally, it is covered with a see-through light-absorbing film that limits light transmittance to 10% or less for wavelengths of 420 nm or below.
