However, in the case of using a material having excellent transparency such as MMA (methyl methacrylate resin), acryl, PC (polycarbonate resin), or nylon as a light-transmitting resin base material for spectacle lenses, it is preferable to use PC having high impact resistance because MMA has low impact resistance, but PC requires a molding temperature of 250 ℃.

Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments of the present invention, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The resin that can be used for the light-transmitting resin base material of the present invention can be melted and then injection-molded through a cavity in a mold to form the light-transmitting resin base material, and as long as it has excellent transparency, the material is not limited herein, and polypropylene-based diethylene glycol dicarbonate, polymethyl methacrylate, methyl methacrylate, and the like can be used.
Titanium cyanine dye
Since the titanium cyanine dye is a known near-infrared absorbing dye and the extreme value of the absorption wavelength varies depending on the molecular structure, various titanium cyanine dyes having extreme values of different absorption wavelengths depending on the application are commercially available as shown in fig. 1.
Commercially available titanocyanine-based dyes, for example, manufactured by Japan K.K.;
the above-mentioned titanium cyanine-based pigments may be dissolved in methyl ethyl ketone (mek), 2-butane (butane), toluene (toluene), etc. as a solvent, and absorption spectra may be analyzed in a state of being dissolved in the solvent, and fig. 1 and 2 are absorption spectra when various titanium cyanine-based pigments having different molecular structures are mixed and dissolved in a toluene solvent at a weight ratio of 5%;
the titanium cyanine dye can be used in the invention, and has a minimum value of a spectral transmittance curve with the transmittance of less than 10% in the target wavelength field of 800 nm-1000 nm;
more than two kinds of titanium cyanine dyes having different extrema in the range of 0.1ppm to 50ppm by weight among the various titanium cyanine dyes shown in FIG. 1 and FIG. 2 are melted and mixed in polycarbonate melted at 250 ℃ to 300 ℃; if the concentration is less than 0.1ppm, the infrared absorption effect is hardly exhibited, and if the concentration exceeds 50ppm, the visible light is blocked, and the function of sunglasses cannot be exerted; in the visible light region (about 500nm to 700nm wavelength region), the lower limit of the allowable transmittance is about 15%;
examples of the combination include the titanocyanine-based dye of FIG. 1(a) having an extreme value of transmittance of less than 10% around 820 nm; and the titanocyanine dye of FIG. 2(a) or FIG. 2(b) having an extreme value of transmittance of less than 10% before or after 980 nm; and (c) a titanocyanine dye of FIG. 1 having an extreme value of transmittance of less than 10% before and after 880 nm.
The spectral transmittance curve of the transparent resin substrate obtained by obtaining a standard mixing amount through experiments in a spectral transmittance curve change in which the transmittance in the visible light range is secured to 15% or more, for example, in the range of 0.1ppm to 50ppm by weight, and appropriately mixing (for example, 15ppm each) a plurality of kinds of titanocyanine-based dyes having different structures, is shown in fig. 3; in this transmission spectrum, a high infrared absorption energy of less than 5% is exhibited between 800nm and 880nm and around 970nm, but a peak of about 10% is exhibited around 900nm, and a spectral transmittance curve is rapidly raised from around 970nm, so that a waveform is formed as a whole, and in this case, a titanium cyanine-based dye having an extremum around 900nm and a titanium cyanine-based dye having an extremum around 970nm are appropriately added in a total weight range of 0.1ppm to 50ppm by weight, a transmission spectrum is obtained for the obtained transparent resin substrate to analyze the spectral transmittance curve, and an optimum amount of the titanium cyanine-based dye combination is determined after repeating the above steps,
further, since the titanocyanine-based dye is generally expensive, it is preferable to obtain a combination at the lowest cost by reducing the amount of the titanocyanine-based dye to be used after achieving a desired spectral transmittance curve.
Mixing the determined combination and amount of the titanium cyanine pigments with polycarbonate melted at 250-300 ℃, and injecting the mixed solution into a mold cavity; thereby obtaining a light-transmitting resin substrate having a spectral transmittance curve in the wavelength region of 800nm to 100anm and a flat minimum region having a transmittance of less than 5%; the light-transmitting resin base material can be used as a material for optical instruments such as lenses and filters, and the size and shape of the above-mentioned cavity can be formed in advance to obtain a light-transmitting resin base material and a spectacle lens having excellent infrared absorption.
The light-transmitting resin substrate of the present invention may be added with a polarizing function, a light-adjusting function, and a vision-correcting function; in addition to the titanocyanine-based coloring matter, other coloring matter or additives may be added as necessary.
