Abstract:
A colored plastic lens, comprising:a plastic substrate having first and second surfaces;an impact resistant resin film with carbon black or an organic pigment dispersed therein, formed on one of the first and second surfaces of the plastic substrate; anda colorless hard coating film formed on the resin film and the surface of the plastic substrate on which the resin film is not formed, the plastic substrate, resin film and the hard coating film forming a lens which is substantially transparent, the hard coating film being made from a composition comprisingat least one epoxysilane or hydrolyzate thereof, wherein any organopolysiloxane present in the hard coating film is polymerized from an epoxysilane selected from the group consisting of .gamma.-glycidoxypropyl trimethoxysilane, .gamma.-glycidoxypropyl triethoxysilane, .gamma.-glycidoxypropyl trimethoxyethoxysilane, .gamma.-glycidoxypropyl triacetoxysilane, .gamma.-glycidoxypropylmethyl dimethoxysilane, .gamma.-glycidoxypropylmethyl diethoxysilane, and .beta.-(3,4-epoxycyclohexyl)ethyl triethoxysilane or is polymerized from a hydrolyzate of an epoxysilane selected from said group, andoptionally, one or more materials selected from the group consisting of inorganic oxide sols, pH adjusting agents, solvents, stabilizers, ultraviolet ray absorbing agents, antioxidants, curing catalysts and curing solvents.
