摘要： A process for producing a photochromic layered product, characterized by preparing a base having a curved surface, applying a photopolymerizable/curable composition containing a photochromic compound and a phosphorus compound photopolymerization initiator to the curved surface of the base, and curing the photopolymerizable/curable composition by irradiation with actinic energy rays having a distribution in which the relative intensity of components ranging in wavelength from 200 nm to 300 nm, excluding 300 nm, accounts for 0 to 5%, the relative intensity of components ranging in wavelength from 300 nm to 400 nm, excluding 400 nm, accounts for 25 to 75%, and the relative intensity of components ranging in wavelength from 400 nm to 500 nm accounts for 25 to 75%, while keeping the base at 100°C or lower. Thus, a homogeneous coating film having an even small thickness and containing a photochromic compound in a high concentration can be formed.

摘要： A curable composition which comprises (1) 0.1 to 20 pts.wt. of a silicon compound which has a silanol group or a functional group generating a silanol group upon hydrolysis and has no radical-polymerizable groups, such as Ϝ-glycidoxypropyltrimethoxysilane, (2) 100 pts.wt. of one or more radical-polymerizable monomers, and (3) 0.01 to 20 pts.wt. of a photochromic compound, wherein the radical-polymerizable monomers comprise a radical-polymerizable monomer having an epoxy group in the molecule, such as glycidyl methacrylate. This curable composition can form a photochromic layer having such excellent photochromism that it assumes a color having a high density and has a high fading rate. The photochromic layer does not release the photochromic compound and comes to have high substrate adhesion through a simple pretreatment. The composition is highly suitable for hard coating.

摘要： A method of producing a laminate comprising preparing a substrate having curved surfaces; applying a photpolymerizable and curable composition containing a photochromic compound and a phosphorus-containing photopolymerization initiator onto the curved surfaces of the base member; and curing the photopolymerizable and curable composition by the irradiation with an active energy ray having a relative intensity profile of 0 to 5% of wavelength components of not shorter than 200 nm but shorter than 300 nm, 25 to 75% of wavelength components of not shorter than 300 nm but shorter than 400 nm and 25 to 75% of wavelength components of not shorter than 400 nm but not longer than 500 nm while maintaining the substrate at not higher than 100°C.
