A laminated body of the present invention includes a melanin-containing layer, wherein the melanin-containing layer is formed by curing a composition that includes at least a melanin, a polymerizable monomer, and a urethane-derived composition. The composition for the laminated body of the present invention is used for producing the laminated body and includes at least a melanin, a polymerizable monomer, and a urethane-derived composition. The optical product of the present invention is formed including the laminated body.

Laminated body for optical purposes that includes a melanin-containing layer and an optical product which includes the laminate

A light control plastic lens, a sheet-like light control element, and a production method for light control plastic lenses are provided. More specifically, a light control plastic lens, such as a high index polarizing property and/or a photochromic plastic lens that is made by cast polymerization is provided. Also provided is a sheet-like light control element for use in the production of the lenses, as well as a production method of such light control plastic lenses. The light control plastic lens has a sheet-like light control element including at least a light control sheet. In particular, the light control plastic lens has a sheet-like light control element, a curable resin layer laminated on at least one surface of the sheet-like light control element, and a polymerizable lens resin layer laminated at least on the curable resin layer.

Light control plastic lens, coated sheet-like light control element for the lens production, and a production method for light control plastic lens
