Film for color compensation, multi-functional film for color compensation and near infrared absorption and plasma display panel filter comprising the same

摘要

The present invention relates to a film for color compensation and a multi-functional film for color compensation and near IR absorption for a PDP filter comprising a cyanine dye represented by the formula 1 below and a plasma display panel filter comprising the same: where definition of R1 to R4 and A are given in the specification. The film for color compensation and the multi-functional film for color compensation and near IR absorption of the present invention selectively absorbs light in the 560-600 nm region, can improve film durability and can improve contrast and color saturation of PDP images.
