PDPs generate near-infrared light during plasma discharge, and these near-infrared rays are used for televisions for home appliances, coolers, and video decks. In order to solve such a problem, the visible light transmittance is high, the near-infrared light cutting efficiency is high, and the selective absorption ability in the near-infrared region is excellent. In addition, development has been made on phthalocyanine compounds having the characteristics of excellent heat resistance, light resistance, and weather resistance.

  As described above, various phthalocyanine compounds have been studied and developed. Conventional phthalocyanine compounds include methanol, alcohols such as ethanol and propanol, cellosolves such as ethyl cellosolve, glycols such as monoethylene glycol and diethylene glycol, acetone and methyl ethyl ketone. It is known that it is soluble in organic solvents such as ketones such as chloroform and toluene (for example, see Patent Document 1). However, conventional phthalocyanine compounds have not been sufficiently soluble in ether solvents. For this reason, there is a problem that even if the use of an ether solvent is appropriate, a sufficient amount of the phthalocyanine compound cannot be blended, and selection of the solvent to be used and the type of resin to be blended is limited. It was.

  In particular, color toner, inkjet ink, household inkjet ink, anti-counterfeit ink, especially anti-counterfeit bar code ink and anti-counterfeit offset ink, goggles lens and shielding plate, for sorting when recycling plastic Dyeing agents, optical recording media, photosensitive dyes for laser therapy, preheating aids during molding of PET bottles, photothermal exchange agents such as thermal transfer and thermal stencil, photothermal exchange agents for thermal rewritable recording, Anti-counterfeit prevention of ID cards, selection of solvents for use in laser heat transmission welding (LTW: Laser Transmission Welding), heat ray shielding agents, near-infrared absorption filters, etc. are limited There was a limit to the applications that can be applied. Therefore, there has been a high demand for phthalocyanine compounds that have high solubility in ether solvents and are useful for applications that cannot be applied conventionally.

The near infrared light cut region is 640 to 1100 nm, and the average light transmittance of the region is designed to be 20% or less, preferably 15% or less. Therefore, if necessary, two or more dyes / phthalocyanine dyes may be combined. It is also preferable to add another dye having absorption in the visible region in order to change the color tone of the filter. It is also possible to produce a filter containing only the color tone dye and to bond it later. In particular, when an electromagnetic wave cut layer such as sputtering is provided, the color tone is important because the hue may be greatly different from the original filter color.

In order to make the filter obtained by the above method more practical, an electromagnetic wave cut layer, an antireflection (AR) layer, and a non-glare (AG) layer that block electromagnetic waves emitted from the flat panel display can be provided. Their manufacturing method is not particularly limited. For example, for the electromagnetic wave cut layer, a sputtering method such as a metal oxide can be used. Usually, In ₂ O ₃ (ITO) to which Sn is added is generally used, but the dielectric layer and the metal layer are formed on the substrate. By alternately laminating by sputtering or the like, it is possible to cut light of 1100 nm or more from near infrared rays, far infrared rays to electromagnetic waves. The dielectric layer is a transparent metal oxide such as indium oxide or zinc oxide, and the metal layer is generally silver or a silver-palladium alloy, and usually three layers and five layers starting from the dielectric layer. 7 or 11 layers are laminated. In this case, the heat generated from the display can be cut at the same time, but since the dye / phthalocyanine dye has an excellent heat ray shielding effect, the heat resistance effect can be further improved. As the substrate, a filter containing a dye / phthalocyanine dye may be used as it is, or may be bonded to a filter containing the dye / phthalocyanine dye after sputtering on a resin film or glass. Moreover, when actually performing electromagnetic wave cutting, it is necessary to install an electrode for grounding. In order to suppress the reflection of the surface and improve the transmittance of the filter, the antireflection layer is made of an inorganic substance such as a metal oxide, fluoride, boride, carbide, nitride, sulfide, vacuum deposition method, sputtering method, There are a method of laminating a single layer or a multilayer by an ion plating method, an ion beam assist method, or the like, a method of laminating a resin having a different refractive index such as an acrylic resin or a fluororesin, or the like. Moreover, the film which gave the antireflection process can also be affixed on this filter. Further, if necessary, a non-glare (AG) layer can be provided. The non-glare (AG) layer can be formed by coating fine particles of silica, melamine, acrylic, etc. with ink in order to scatter transmitted light for the purpose of widening the viewing angle of the filter. The ink can be cured by thermal curing or photocuring. Further, a non-glare-treated film can be pasted on the filter. Further, if necessary, a hard coat layer can be provided.

  The configuration of the filter for the flat panel display can be changed as required. Usually, an antireflection layer is provided on a filter containing a near infrared absorbing compound, and if necessary, a non-glare layer is provided on the opposite side of the antireflection layer. In addition, when combining an electromagnetic wave cut layer, a filter containing a near infrared ray absorbing compound is used as a base material, and an electromagnetic wave cut layer is provided thereon, or a filter containing a near infrared ray absorbing compound and a filter having an electromagnetic wave cutting ability are provided. Can be made by pasting together. In that case, an antireflection layer can be further produced on both sides, or if necessary, an antireflection layer can be produced on one side and a non-glare layer can be produced on the opposite side. In addition, when adding a dye having absorption in the visible region for color correction, the method is not limited.
