Abstract
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.
Claims41
A multilayer coating in which a plurality of photocurable resin cured films are layered, wherein at least two adjacent layers comprise the same hindered phenol antioxidant in different amounts, and wherein the antioxidant has at least one hindered phenol group, said hindered phenol group containing none or only one sterically hindered alkyl group selected from the group consisting of an i-propyl group, an i-butyl group, and a tert-butyl group and wherein said adjacent layers comprise urethane meth(acrylate),
- wherein said multilayer coating further comprises an amine compound;
- wherein said amine compound is present in said multilayer coating to prevent the generation of hydrogen gas.
