Further, the plastic lens C in the present embodiment may have various coating layers on the lens substrate in accordance with the purpose and application. Similar to the plastic lens A, the coating layer can contain a phosphor.

[Plastic eyeglass lenses]
A plastic spectacle lens can be obtained using the plastic lens of the present embodiment. If necessary, a coating layer may be provided on one side or both sides.

  Specific examples of the coating layer include a primer layer, a hard coat layer, an antireflection layer, an antifogging coat layer, a stainproof layer, and a water repellent layer. Each of these coating layers can be used alone, or a plurality of coating layers can be used in multiple layers. When a coating layer is applied to both sides, a similar coating layer or a different coating layer may be applied to each surface.

  These coating layers are the phosphor used in this embodiment, an infrared absorber for the purpose of protecting the eyes from infrared rays, a light stabilizer and an antioxidant for the purpose of improving the weather resistance of the lens, and the fashionability of the lens. For the purpose, dyes and pigments, photochromic dyes and photochromic pigments, antistatic agents, and other known additives for enhancing the performance of the lens may be used in combination. For the layer to be coated by coating, various leveling agents for the purpose of improving coating properties may be used.

  The primer layer is usually formed between a hard coat layer described later and the lens. The primer layer is a coating layer for the purpose of improving the adhesion between the hard coat layer formed thereon and the lens, and in some cases, the impact resistance can also be improved. Any material can be used for the primer layer as long as it has high adhesion to the obtained lens, but usually a primer mainly composed of urethane resin, epoxy resin, polyester resin, melamine resin, or polyvinyl acetal. A composition or the like is used. The primer composition may use an appropriate solvent that does not affect the lens for the purpose of adjusting the viscosity of the composition. Of course, you may use it without a solvent.

The primer layer can be formed by either a coating method or a dry method. In the case of using the coating method, the primer layer is formed by solidifying after applying the primer composition to the lens by a known coating method such as spin coating or dip coating. When performing by a dry method, it forms by well-known dry methods, such as CVD method and a vacuum evaporation method. When forming the primer layer, the surface of the lens may be subjected to a pretreatment such as an alkali treatment, a plasma treatment, or an ultraviolet treatment as necessary for the purpose of improving adhesion.
The hard coat layer is a coating layer for the purpose of imparting functions such as scratch resistance, abrasion resistance, moisture resistance, warm water resistance, heat resistance, and weather resistance to the lens surface.

  The hard coat layer is generally composed of an organic silicon compound having a curing property and an element selected from the element group of Si, Al, Sn, Sb, Ta, Ce, La, Fe, Zn, W, Zr, In, and Ti. A hard coat composition containing at least one kind of fine particles composed of one or more kinds of oxide fine particles and / or a composite oxide of two or more elements selected from these element groups is used.

  In addition to the above components, the hard coat composition includes at least amines, amino acids, metal acetylacetonate complexes, organic acid metal salts, perchloric acids, perchloric acid salts, acids, metal chlorides and polyfunctional epoxy compounds. It is preferable to include any of them. A suitable solvent that does not affect the lens may be used for the hard coat composition, or it may be used without a solvent.

  The hard coat layer is usually formed by applying a hard coat composition by a known application method such as spin coating or dip coating, followed by curing. Examples of the curing method include thermal curing, a curing method by irradiation with energy rays such as ultraviolet rays and visible rays, and the like. In order to suppress the occurrence of interference fringes, the refractive index of the hard coat layer is preferably in the range of ± 0.1 in the difference in refractive index from the lens.

The antireflection layer is usually formed on the hard coat layer as necessary. There are inorganic and organic antireflection layers. In the case of inorganic systems, inorganic oxides such as SiO ₂ and TiO ₂ are used, and vacuum deposition, sputtering, ion plating, ion beam assist, and CVD are used. It is formed by the dry method. In the case of an organic type, it is formed by a wet method using a composition containing an organosilicon compound and silica-based fine particles having internal cavities.

The antireflection layer has a single layer and a multilayer, and when used in a single layer, the refractive index is preferably at least 0.1 lower than the refractive index of the hard coat layer. In order to effectively exhibit the antireflection function, a multilayer antireflection film is preferably used. In that case, a low refractive index film and a high refractive index film are alternately laminated. Also in this case, the refractive index difference between the low refractive index film and the high refractive index film is preferably 0.1 or more. Examples of the high refractive index film include ZnO, TiO ₂ , CeO ₂ , Sb ₂ O ₅ , SnO ₂ , ZrO ₂ , and Ta ₂ O _5, and examples of the low refractive index film include an SiO ₂ film. .

  On the antireflection film layer, an antifogging layer, an antifouling layer, and a water repellent layer may be formed as necessary. As a method for forming the antifogging layer, the antifouling layer, and the water repellent layer, as long as the antireflection function is not adversely affected, the processing method and processing materials are not particularly limited, and a known antifogging treatment is possible. Methods, antifouling treatment methods, water repellent treatment methods, and materials can be used. For example, in the antifogging treatment method and the antifouling treatment method, a method of covering the surface with a surfactant, a method of adding a hydrophilic film to the surface to make it water absorbent, a method of covering the surface with fine irregularities and increasing water absorption Examples thereof include a method of absorbing water by utilizing photocatalytic activity, and a method of preventing water droplet adhesion by applying a super water-repellent treatment. Further, in the water repellent treatment method, a method of forming a water repellent treatment layer by vapor deposition or sputtering of a fluorine-containing silane compound or the like, or a method of forming a water repellent treatment layer by coating after dissolving the fluorine-containing silane compound in a solvent Etc.

  The optical resin composition of the present embodiment can be bonded as a sheet or film to a windshield such as a helmet or a windshield such as a vehicle.

In addition, this invention is not limited to the above-mentioned embodiment, A various aspect can be taken in the range which does not impair the effect of this invention.
For example, an optical material can be obtained without using the “composition for an optical material containing a phosphor” in the above-described embodiment. If the phosphor is not included, the “composition for optical material” of the above-described embodiment can be used, and the same configuration can be adopted. This aspect will be described below. In addition, when it is the same as that of the above-mentioned embodiment, description is abbreviate | omitted suitably.

  The optical material in the said aspect can be used as a plastic lens provided with the lens base material, the film layer laminated | stacked as needed, and a coating layer. The phosphor may be contained in at least one of the lens substrate, the film layer, and the coating layer.

Specifically, a dispersion obtained by preparing a molded body (lens substrate or optical film) using a composition for optical materials that does not contain a phosphor, and then dispersing the phosphor in water or a solvent. The molded body is dipped in and the phosphor is impregnated in the molded body and dried. An optical material can be prepared using the molded body thus obtained.
In addition, after the optical material is prepared, the optical material can be impregnated with the phosphor. For example, a plastic spectacle lens including a lens substrate, and a film layer and a coating layer laminated as necessary can be immersed in a dispersion containing the phosphor to impregnate the phosphor.
The impregnation amount of the phosphor can be controlled to a desired impregnation amount by the concentration of the phosphor in the dispersion, the temperature of the dispersion, and the time during which the optical material resin composition is immersed. The higher the concentration, the higher the temperature, and the longer the immersion time, the greater the amount of impregnation. When it is desired to precisely control the amount of impregnation, it is carried out by repeating immersion several times under the condition that the amount of impregnation is small.

In addition, a phosphor-containing coating layer can be formed on an optical material such as a plastic lens using a coating material containing a phosphor.
The optical material having such a configuration can be suitably used as a plastic spectacle lens.
