Embodiment 1

[0120] Example 1: Preparation of color compensation film using anthraquinone dye and cyanine dye

[0121] Under stirring, based on the total solution, 0.06 wt% or 0.12 wt% of 1,4-diaminoanthraquinone dye (Green-5B available from M-Dohmen) for improving the lightfastness of cyanine dyes and 0.02 wt% of a cyanine dye (HAO-01 available from Hayashibara Biochemical) for absorbing visible light at about 585 nm was added to a mixture of 6.0 g of acrylic polymer binding resin (GS-1000 available from Soken) and 4.0 g of 1 , 3-dioxolane solvent (available from Aldrich) in a solution to prepare a uniform coating solution. Next, the coating liquid thus prepared was applied onto the primer-treated surface of an optical film (A4100 available from Toyobo) by using a wire bar. Thereafter, the coated film was dried at 80° C. for 1 minute by using hot air to prepare a film having a 7 μm thick color compensation layer.

Embodiment 2

[0122] Example 2: Preparation of color compensation film using anthraquinone dye and cyanine dye (2)

[0123] Under stirring, based on the total solution, 0.06 wt% or 0.12 wt% of 1,4-diaminoanthraquinone dye (available from M-Dohmen as Blue-RR) for improving the light fastness of cyanine dyes and 0.02 wt% of a cyanine dye (HAO-01 available from Hayashibara Biochemical) for absorbing visible light at about 585 nm was added to a mixture of 3.5 g of acrylic polymer binding resin (IR-G205 available from Nippon Shokubai) and 6.5 g A coating solution was prepared in a solution consisting of 2-butanone (available from Aldrich). After that, the coating liquid thus prepared was applied onto the primer-treated surface of an optical film (A4100 available from Toyobo) by using a wire bar coater. Next, by using hot air, the coated film was dried at 80° C. for 1 minute to prepare a film having a color compensation layer with a thickness of 7 μm.

Embodiment 3

[0124] Example 3: Preparation of NIR absorbing film using anthraquinone dye and cyanine dye

[0125] Under stirring, based on the total solution, 0.06 wt% of 1,4-diaminoanthraquinone dye (Blue-AP available from YaBang) for improving the lightfastness of cyanine dyes and 0.03 wt% of absorbing A cyanine dye (TZ-115 available from AsahiDenka) with NIR at about 850 nm was added to a solution consisting of 6.0 g of acrylic polymer binding resin (available from Soken's GS-1000) and 4.0 g of toluene, A coating liquid is prepared. Next, the coating liquid thus prepared was applied onto the primer-treated surface of an optical film (A4100 available from Toyobo) by using a wire bar coater. Next, by using hot air, the coated film was dried at 80° C. for 1 minute to prepare a film having a color compensation layer with a thickness of 7 μm.

Abstract

Disclosed herein is a composition for use as a film on an image display filter. In some embodiments, the composition includes a cyanine dye exhibiting an absorption maximum in the wavelength region from about 830 to about 880 nm or from about 580 to about 600 nm and an anthraquinone dye comprising an anthraquinone compound substituted with an amino group in one or more positions selected from the 1-, 4-, 5-, and 8-position.

Description

[0001] Cross-references to related applications [0002] This non-provisional application claims priority under 35 U.S.C. §199(a) to Korean Patent Application No. 2005-55699 filed June 27, 2005, which is hereby incorporated by reference. technical field [0003] The present invention relates to near infrared absorbing and color compensating film compositions for displays such as plasma displays. Background technique [0004] Plasma displays are self-emitting displays, and they have the advantages of large display area and small thickness. Because of these advantages, plasma displays have been used in large-screen televisions. In a plasma display, discharge gas generates ultraviolet (UV) rays to excite phosphors to emit light. In practice, a substantial amount of near infrared light is emitted from the plasma display. [0005] The wavelength range in the near-infrared region overlaps with a band around 930nm, which is used in remote controls for many home electronics devic...
