To provide a photocurable liquid resin composition that can produce cured products exhibiting a high refractive index, good shape restorability, and superior adhesion to substrates. The photocurable resin composition comprises (A) 20-80 wt % of a urethane (meth) acrylate obtained by reacting a polyether polyol having an alkyleneoxy structure in the molecule, an organic polyisocyanate compound, and a (meth) acrylate containing a hydroxyl group, (B) 10-70 wt % of a monofunctional ethylenically unsaturated compound, (C) 5-25 wt % of a (meth) acrylate monomer having four or more functional groups, and (D) 0.1-10 wt % of a photoinitiator. Cured products are useful for forming an optical part such as a lens of a lens sheet or a back light using the lens sheet.
The present invention relates to a multilayer coating in which a plurality of photocurable resin cured films are layered on a substrate, wherein at least two adjacent layers comprise the same hindered phenol-type antioxidant.
The multilayer coating can be applied onto a substrate, such as glass fibers, vinyl chloride sheets, polycarbonate sheets, glass plates, polyethylene films, wood, acrylic sheets, metal plates, and the like.
