Reactive polymeric dyes are provided comprising a chromophoric moiety derived from at least one free radically polymerizable dye and an azlactone moiety derived from 2-alkenylazlactone such that the free radically polymerizable dye is incorporated into the backbone of the polymer. Alternatively, 2-alkenylazlactone is polymerized and then derivatized with a nucleophilic dye or dyes, such that the chromophoric portion of the dye is pendent to the polymer backbone. Both types of reactive polymeric dyes may also contain additional polymerized monomeric units. The reactive polymeric dyes of the present invention can be used in a photoresist system and in particular in a color proofing construction.

Provided by the present invention are an anthraquinone colorant for coloring an ophthalmic lens represented by the following general formula (1):
and a high molecular anthraquinone colorant obtained by forming a covalent bond between the anthraquinone colorant and a monomer for an ophthalmic lens. The monomer for an ophthalmic lens preferably has a polydimethylsiloxane structure. Further provided by the present invention is an ophthalmic lens material formed from a composition containing the colorant and a monomer for an ophthalmic lens having an unsaturated double bond, and the lens material containing a polymer comprising the monomer for an ophthalmic lens as a monomer unit.
The present invention is a laminated glass [H] which uses, as an intermediate film, a sheet [G] that is formed from a resin composition [F] that is prepared by blending a total amount of 0.001 to 2.0 parts by weight of a metal oxide particulate and/or a near infrared-absorbing pigment having a function of shielding infrared ray, into 100 parts by weight of a specific hydrogenated block copolymer [D] and/or a modified hydrogenated block copolymer [E]. The present invention provides a laminated glass which has excellent infrared shielding function, moisture resistance and heat resistance.

The present invention pertains to a laminated glass obtained by: interposing, between glass plates, a resin sheet comprising a resin composition obtained by blending 100 parts by weight of a specific modified hydrogenated block-copolymer having an introduced acid anhydride group, and a total of 0.001 to 2.0 parts by weight of a near infrared ray-absorbing pigment and/or a metal oxide particulate having a function of shielding infrared ray, to obtain a laminate; and integrally bonding the laminate including the glass plates and the resin sheet. The aspects of the invention provide a novel hydrogenated block copolymer having an acid anhydride group; a resin composition that includes the hydrogenated block copolymer, has excellent heat insulating function, and is suitable as a laminated glass intermediate film-forming material excellent in moisture resistance and durability; a resin sheet made of the resin composition; and a laminated glass in which the resin sheet is interposed between glass plates through an adhesive and the laminate including the glass plates and the resin sheet is adhesively integrated.
