Abstract

A diimmonium salt compound having a relatively wide near-infrared absorption wavelength range, while exhibiting good heat resistance and wet heat resistance has been found. The compound is stable not only in a cured film layer formed by a commonly used process but also in a coating resin layer using a binder resin having a relatively low Tg wherein binder resins of a wide Tg range can be used. A near-infrared absorbing film is created by using such a compound, and an optical filter for PDP is produced by utilizing such a near-infrared absorbing film. Specifically disclosed is a near-infrared absorbing film exhibiting excellent stability, wherein a diimmonium salt compound represented by the formula (1) below is used. Also specifically disclosed is an optical filter for PDP utilizing the near-infrared absorbing film. (1) (In the formula (1), R1-R8 independently represent a hydrogen atom or an optionally substituted aliphatic hydrocarbon residue; and X- and Y- respectively represent a monovalent anion different from each other.)

Therefore, it is necessary to cut the chromatic light to the extent that it reaches the front of the display. Therefore, an aerofic absorption filter or a light sheet which retains the calender absorption compound on the transparent support film is generally used, but also has the following method, wherein the coating layer having near-infrared absorption energy contains calender absorption. A compound capable of absorbing the coating layer of near-infrared rays and neon light at the same time. Further, examples of the gas absorbing compound include a tetraazaporphyrin system, a phthalocyanine system, a squaric acid π, a _ human methyl azo system, a diphenyl hydrazine, a south system, an oxonium system or an azo group. In particular, when the adhesive layer contains these compounds, it is necessary to fully consider the mosquitoes and the like. For example, the tetraaza 4 (tetra) compound is relatively stable 'as long as other compounds may be stabilized or used. The adhesive which can be used in the invention is not particularly limited as long as it forms a transparent layer on the surface of the transparent support film and does not impair the function as an optical filter, and examples thereof include acrylic, polyester, and polyfluorene. An adhesive such as an amine-based polyamino phthalate ester, a polyolefin-based, a polycarbonate-based, a gel-based or a fluorene-based resin, is excellent in transparency, adhesion, heat resistance, etc. 5, preferably acrylic acid. A resin adhesive. The acrylic resin adhesive contains an acrylic alkyl ester having no functional group as a main component, and is made of an acrylic alkyl ester or an acrylic alkyl ester having a functional group of 122098.doc -20-200813494.
