NEAR-INFRARED-ABSORBING FILM AND OPTICAL FILTER EMPLOYING THE SAME FOR PLASMA DISPLAY PANEL

摘要

A near-infrared-absorbing film which is excellent in heat resistance and moist-heat resistance and retains optical properties including satisfactory near-infrared-absorbing ability. The near-infrared-absorbing film comprises a transparent base and a pressure-sensitive adhesive layer formed on one side of the base from a pressure-sensitive adhesive comprising a near-infrared-absorbing dye and a copolymer of a constituent monomer which is a Ccycloalkyl ester of (meth)acrylic acid. This near-infrared-absorbing film may be laminated to other functional film(s) to give a laminate useful as an optical filter for PDPs.
