Abstract:
Disclosed herein are a near-infrared absorbing and color compensation film composition and a film using the film composition. The film composition comprises i) at least one colorant selected from the group consisting of an ionic compound of a near-infrared absorbing cyanine colorant cation having a maximum absorption wavelength in the range of 820 nm to 950 nm and a metal complex colorant anion, an ionic compound of a near-infrared absorbing diimmonium colorant cation having a maximum absorption wavelength in the range of 950 nm to 1,100 nm and a metal complex colorant anion, and an ionic compound of a selective visible light absorbing cyanine colorant cation having a maximum absorption wavelength in the range of 580 nm to 600 nm and a metal complex colorant anion, and ii) an adhesive; and a film using the film composition.When the film composition is used to produce an adhesive film or an antireflective composite film, the price of raw materials used and the number of production steps can be reduced. Therefore, the film composition can be effectively applied to a front filter for a plasma display.
