[Determining the amount of titanium cyanine dyes] In the various titanium cyanine pigments shown in Fig. 1 and Fig. 2, each of the two types having different extreme values is in the range of 〇.ippm to 5〇ppm. Above, it is melted and mixed at 250. (: ~300 ° C dissolved in the polycarbonate; if less than 0.1 ppm, it will almost no infrared absorption effect, if more than 50ppm will even block visible light (Visible Light), and can not play the role of sunglasses; In the visible light region (in the wavelength range of about 500 nm to 700 nm), the allowable lower transmittance limit is about 15%; for example, the combination may have a transmittance of less than 1% of the maximum value before and after 820 nm. 1 (a) Titanium cyanine pigment; and Fig. 2 (a) or Fig. 2 (b) Titanium cyanine pigment having a transmittance of less than 1〇% before and after 980 nm; and transmittance before and after 880 nm Figure 1 (c) Titanium Cyanine Pigment, which is less than 1% of the extreme value.

It may be one or more types; in addition, a titanium cyanine dye, a coloring matter for coloring, or other additives may be added to the resin. _ The translucent resin substrate of the present invention is applicable not only to general glasses, sunglasses (including those having a polarizing function or a dimming function), but also to eyeglass lenses such as front-mounted glasses and goggles. Concentrated mirrors and other optical instruments. 201209082 [Brief Description of the Drawings] Fig. i is a diagram showing an example of absorption spectra when various titanium cyanine dyes having a molecular structure are mixed at a concentration of 5% by weight in the toluene dissolution age. 5 (a) and (b) are graphs showing absorption spectra of 5% by weight of a mixture of various titanium phthalocyanine dyes having different molecular structures in a toluene solvent. The figure is one of the examples of transmission spectra obtained by appropriately mixing several kinds of eucalyptus pigments having different structures in the pm.lppm~5〇Ppm weight range. _ Figure 4 Ride) ~ (4) Table showing the absorption spectrum of the thief color pigment of the embodiment of the present invention. Fig. 5 is a graph showing the absorption spectrum of the light-transmitting resin substrate obtained in the examples of the present invention, which is obtained by the embodiment of the present invention.
