FILM FOR OPTICAL FILTER AND OPTICAL FILTER COMPRISING SAME FOR PLASMA DISPLAY PANEL

摘要

A film for optical filters that has excellent light resistance and an optical filter for plasma display panels that comprises the film are developed using a pressure-sensitive adhesive comprising a crosslinkable acrylic resin, a crosslinking agent, and a dye absorbing neon light. Use is made of a pressure-sensitive adhesive comprising a crosslinkable acrylic resin and a crosslinking agent, the resin being obtained by copolymerizing 70.1-99.8 wt.% alkyl (meth)acrylate in which the alkyl group has 4-12 carbon atoms, 0.1-10 wt.% hydroxylated monomer copolymerizable with the alkyl (meth)acrylate, and 0.1-19.9 wt.% other monomer copolymerizable with both the alkyl (meth)acrylate and the hydroxylated monomer.  A dye absorbing neon light is highly stable in a layer of the pressure-sensitive adhesive.  By forming the pressure-sensitive adhesive layer on one side of a transparent substrate, a film for optical filters that has excellent light resistance and an optical filter for plasma display panels that comprises the film have been developed.
