る。2. Description of the Related Art Various devices such as a remote control device for electric devices such as televisions, audio devices, and air conditioners, automatic doors, alarm devices and the like have been put into practical use as devices utilizing infrared rays.
The light receiving section of these devices requires a filter that selectively transmits wavelengths in the infrared region. Near-infrared rays having a wavelength of 800 to 1000 nm are often used in remote control devices, automatic doors, alarm devices, etc., which are widely used at present. Therefore, in the above device, in order to avoid malfunction due to visible light, a filter that blocks wavelengths in the visible light region and transmits only wavelengths in the infrared region is required. Further, since these infrared ray transmitting filters are often exposed and used due to the nature of the device, they are required to have excellent mechanical strength and weather resistance and to be resistant to scratches on the surface.

A large amount of compound is required, and a slight amount of impurities in the dye greatly reduces the molecular weight of the aromatic polycarbonate resin, hinders stable molding, and lowers mechanical strength.

それらの混合物でもかまわない。The aromatic polycarbonate resin used in the present invention is derived from a dihydric phenol. It is usually obtained by reacting a dihydric phenol with a carbonate precursor by a solution method or a melting method. Examples of the dihydric phenol used here include 2,2-bis (4-hydroxyphenyl) propane (hereinafter abbreviated as bisphenol A), bis (4-hydroxyphenyl) methane, and 2,2.
-Bis (4-hydroxy-3,5-dimethylphenyl)

Further, examples of the carbonate precursor include carbonyl halide, diaryl carbonate, haloformate and the like, and specific examples thereof include phosgene, diphenyl carbonate, dihaloformate of dihydric phenol and a mixture thereof. In producing the aromatic polycarbonate resin, the dihydric phenol may be used alone or in combination of two or more kinds. Also, a suitable molecular weight regulator,
A branching agent, a catalyst for accelerating the reaction and the like can also be used. Two or more aromatic polycarbonate resins thus obtained may be mixed. The shape of the aromatic polycarbonate resin of the present invention may be pellets, powder, or a mixture thereof.

It is not possible to obtain a filter that blocks a desired wavelength in the visible light range and transmits only a wavelength in the infrared range. Further, it is not possible to obtain a resin composition having excellent heat resistance that can withstand molding of an aromatic polycarbonate resin.

処理された染料が好ましい。Among these, the anthraquinone green dye and the perinone red dye are preferably dyes treated with an acid such as hydrochloric acid or acetic acid in the manufacturing process. When producing a dye, a metal-based catalyst is used as the catalyst. If a large amount of this metal-based catalyst remains in the dye, the molecular weight of the aromatic polycarbonate resin containing the dye is significantly reduced. Therefore, a dye in which the metal catalyst is reduced by adding an acid such as hydrochloric acid or acetic acid to the dye formed in the dye manufacturing process to dissolve the metal catalyst and filtering it is preferable. By using the dye produced by this method, it is possible to perform stable molding with little decrease in the molecular weight of the aromatic polycarbonate resin. Particularly, since the anthraquinone green dye and the perinone red dye are used in a relatively large amount, the acid-treated dye is preferable.
