Description

Molded article and polymerizable composition for optical materials The present invention relates to a molded article containing a photochromic compound and a polymerizable composition for optical materials. Plastic lenses have rapidly spread to optical elements such as spectacle lenses and camera lenses because they are lighter and less likely to break than inorganic lenses. In recent years, the development of plastic lenses having photochromic performance has been underway. Among them, lenses obtained from poly(thio)urethane are attracting attention because they have a high refractive index and excellent physical properties such as strength. Patent Document 1 describes a lens comprising a composition containing a predetermined photochromic compound and a di(meth)acrylate compound. Paragraph 0009 states that when a urethane resin or a thiourethane resin having a high refractive index is used, isocyanate, which is a resin raw material at the monomer stage, reacts with the photochromic compound and the photochromic performance is completely lost. Patent Document 2 discloses a lens provided with a coating layer comprising a composition containing a photochromic compound having a chromene skeleton and a phenol compound on the surface of a thiourethane-based plastic lens. Patent Document 3 discloses a photochromic lens having a lens substrate made of a thiourethane resin and a photochromic film formed by applying a solution containing a photochromic compound and a radically polymerizable monomer on the substrate. Patent Document 4 discloses a compound having photochromic properties. Patent Document 5 discloses a polymerizable composition for optical materials containing one or more isocyanate compounds selected from aliphatic isocyanate compounds and alicyclic isocyanate compounds, a polyfunctional active hydrogen compound, and a photochromic compound. Patent Document 6 discloses a polymerizable composition for an optical material containing a polyisocyanate compound, a predetermined polyol compound, a bifunctional or higher-functional active hydrogen compound, and a photochromic compound. In this document, it is described that the molar ratio of the NCO groups contained in the polyisocyanate compound to the total of the OH groups and SH groups contained in the active hydrogen compound and the polyol compound (NCO groups / (OH groups + SH groups)) is in the range of 0.8 to 1.2, and the most preferable range is in the range of 0.9 to 1.1. Japanese Patent Application Laid-Open No. 8-272036, Japanese Patent Application Laid-Open No. 2005-23238, Japanese Patent Application Laid-Open No. 2008-30439, Japanese Patent Application Laid-Open No. 2011-144181, International Publication No. 2014 / 002844 Pamphlet, International Publication No. 2015 / 115648 Pamphlet, U.S. Patent No. 6506538, Japanese Patent Application Laid-Open No. 2005-305306, International Publication No. 2005 / 087829 Pamphlet, International Publication No. 2006 / 109765 Pamphlet, International Publication No. 2007 / 020817 Pamphlet, International Publication No. 2007 / 020818 Pamphlet, International Publication No. 2014 / 002844 Pamphlet, International Publication No. 2015 / 115648 Pamphlet The present inventors investigated the photochromic performance of the resin molded body obtained in the examples of Patent Document 6. As a result, it was found that when the "molar ratio of the NCO groups contained in the polyisocyanate compound to the total of the OH groups and SH groups contained in the active hydrogen compound and the polyol compound (NCO groups / (OH groups + SH groups))" in the resin composition is more than 1.0, the deterioration of the photochromic performance is suppressed as compared with the case where the ratio is 1.0. Therefore, the present inventors confirmed the residue concentrations of NCO groups and SH groups in the resin molded body by IR analysis, and found that there is a correlation between the stability of the photochromic performance of the resin molded body and the remaining SH group concentration in the resin molded body. Note that no correlation was confirmed between the stability of the photochromic performance and the remaining NCO group concentration. Furthermore, it was found that if the molar ratio in the resin composition is in a specific range exceeding 1.0, the remaining SH group concentration in the resin molded body can be suppressed. That is, it was found that by setting the molar ratio in the resin composition within a predetermined range containing a large amount of NCO groups and reducing the remaining SH group concentration in the resin molded body to less than a predetermined value, the deterioration of the photochromic performance over time can be suppressed.

In this embodiment, the functional group equivalent ratio (B / A) of the polyol compound (B) to the polyisocyanate compound (A) has a lower limit of 0.02 or more, preferably 0.10 or more, more preferably 0.15 or more, still more preferably 0.20 or more, particularly preferably 0.25 or more, and an upper limit of 0.60 or less, preferably 0.50 or less, more preferably 0.40 or less, still more preferably 0.30 or less. The upper limit and the lower limit can be combined as appropriate. The functional group equivalent ratio (C / A) of the active hydrogen compound (C) to the polyisocyanate compound (A) has a lower limit of 0.30 or more, preferably 0.40 or more, more preferably 0.50 or more, still more preferably 0.60 or more, and an upper limit of 0.99 or less, preferably 0.98 or less, more preferably 0.90 or less, still more preferably 0.80 or less. The upper limit and the lower limit can be combined as appropriate. By being in the range of the equivalent ratio, it is possible to provide an optical material with excellent balance, which exhibits high photochromic performance and has excellent mechanical physical properties that are characteristic of poly(thio)urethane resins. For example, when the compound represented by the general formula (I) is polyethylene glycol, the color development performance is further improved and the cloudiness of the polymer is further suppressed when the functional group equivalent ratio (B / A) is 0.1 to 0.6. Also, when the compound represented by the general formula (I) is polypropylene glycol, the color development performance is further improved and the cloudiness of the polymer is further suppressed when the functional group equivalent ratio (B / A) is 0.06 to 0.6. Regarding the compound represented by the general formula (II), the color development performance is further improved and the cloudiness of the polymer is further suppressed when the functional group equivalent ratio (B / A) is 0.06 to 0.6. Also, when the compound represented by the general formula (III) is a polyethylene glycol adduct of bisphenol A or a polypropylene glycol adduct of bisphenol A, the color development performance is further improved and the cloudiness of the polymer is further suppressed when the functional group equivalent ratio (B / A) is 0.06 to 0.6. Also, when the compound represented by the general formula (IV) is a polyester compound obtained by reacting 3-methyl-1,5-pentanediol with an equimolar mixture of adipic acid and isophthalic acid in an equimolar amount, the color development performance is further improved and the cloudiness of the polymer is further suppressed when the functional group equivalent ratio (B / A) is 0.02 to 0.2. In the composition, the molar ratio of the NCO groups contained in the polyisocyanate compound (A) to the total of the OH groups and SH groups contained in the active hydrogen compound (C) and the polyol compound (B) (NCO groups / (OH groups + SH groups)) is in the range of 1.1 to 1.6, preferably in the range of 1.25 to 1.6, more preferably in the range of 1.25 to 1.5, and particularly preferably in the range of 1.25 to 1.4. When the molar ratio of NCO groups / (OH groups + SH groups) is within the above range, the molded body obtained from the polymerizable composition of the present invention can suppress the temporal decrease in photochromic performance, and thus can stably exhibit photochromic performance. The photochromic compound (D) can be used in an amount of 10 ppm to 5000 ppm based on the total amount of the isocyanate compound (A), polyol compound (B), and active hydrogen compound (C). When preparing a polymerizable composition by mixing a polyisocyanate compound (A), a polyol compound (B), an active hydrogen compound (C), a photochromic compound (D), and other additives, the temperature is usually 25°C or lower. From the perspective of the pot life of the polymerizable composition, it may be preferable to lower the temperature further. However, when the solubility of the catalyst, internal release agent, and additives in the monomer is not good, it is also possible to warm them in advance and dissolve them in the monomer and resin modifier. The mixing order and method of each component in the composition are not particularly limited as long as each component can be uniformly mixed, and can be carried out by known methods. Examples of known methods include a method of preparing a masterbatch containing a predetermined amount of additives and dispersing / dissolving this masterbatch in a solvent. In this embodiment, a molded article can be obtained by polymerizing and curing the polymerizable composition. The SH group concentration of the molded article can be determined by IR analysis. For example, using an IR analyzer Spectrum One manufactured by PERKIN-ELMER, measure the IR spectrum of a resin sample cut and polished to a thickness of 0.35 mm, and use the absorption of NCO at 2257 cm －１ , and SH at 2550 cm －１ to obtain the absorbance by the baseline method, and it can be determined by calculation using the following formula from a calibration curve prepared in advance. The SH group concentration of the molded article measured in this way is less than 1.0 wt%, preferably 0.5 wt% or less, more preferably 0.3 wt% or less, and particularly preferably 0.1 wt% or less. It is most preferable that the SH group of the molded article is not substantially detected. The molded article within this range can suppress the decrease in photochromic performance over time, and thus can stably exhibit photochromic performance. The molded article of this embodiment can be used as an optical material. In this embodiment, the manufacturing method of the optical material is not particularly limited, but casting polymerization can be mentioned as a preferable manufacturing method. First, a polymerizable composition is injected between molding molds held by a gasket, a tape, or the like. At this time, depending on the physical properties required for the obtained plastic lens, it is often preferable to perform a defoaming treatment under reduced pressure, a filtration treatment such as pressurization or reduced pressure, etc. as necessary. Regarding the polymerization conditions, since the conditions vary greatly depending on the composition of the polymerizable composition, the type and amount of the catalyst used, the shape of the mold, etc., they are not limited, but are generally carried out at a temperature of -50 to 150°C for 1 to 50 hours. In some cases, it is preferable to hold or gradually raise the temperature in the temperature range of 10 to 150°C and cure it in 1 to 25 hours. The optical material may be subjected to a treatment such as annealing as necessary. The treatment temperature is usually carried out between 50 and 150°C, preferably at 90 to 140°C, and more preferably at 100 to 130°C. In this embodiment, when molding the resin, in addition to the above-mentioned "other components", various additives such as a chain extender, a crosslinking agent, a light stabilizer, an ultraviolet absorber, an antioxidant, a bluing agent, an oil-soluble dye, a filler, and an adhesion improver may be added in the same manner as known molding methods according to the purpose. <Usage> The polymerizable composition of this embodiment can be obtained as molded bodies of various shapes by changing the type of mold during casting polymerization. The molded body has photochromic performance, a high refractive index, and high transparency, and can be used for various optical materials such as plastic lenses. In particular, it can be suitably used as a plastic spectacle lens or a plastic polarizing lens. [Plastic spectacle lens] The plastic spectacle lens using the lens substrate made of the molded body of this embodiment may be used with a coating layer provided on one side or both sides as necessary. The plastic spectacle lens of this embodiment is composed of a lens substrate made of the above-mentioned polymerizable composition and a coating layer. As the coating layer, specifically, a primer layer, a hard coat layer, an antireflection layer, an antifogging coat layer, an antifouling layer, a water repellent layer, etc. can be mentioned. These coating layers can be used individually or in a multilayered structure with multiple coating layers. When applying the coating layer on both sides, the same coating layer or different coating layers can be applied to each side. These coating layers may each be used in combination with an ultraviolet absorber for the purpose of protecting the lens and eyes from ultraviolet rays, an infrared absorber for the purpose of protecting the eyes from infrared rays, a light stabilizer or antioxidant for the purpose of improving the weather resistance of the lens, a dye or pigment for the purpose of enhancing the fashionability of the lens, an antistatic agent, and other known additives for enhancing the performance of the lens. For the layer to be coated by application, various leveling agents for the purpose of improving the coatability may be used. The primer layer is usually formed between the hard coat layer described later and the lens. The primer layer is a coating layer intended to improve the adhesion between the hard coat layer formed thereon and the lens, and in some cases, it is also possible to improve the impact resistance. Any material can be used for the primer layer as long as it has high adhesion to the obtained lens, but usually, a primer composition mainly composed of a urethane resin, an epoxy resin, a polyester resin, a melanin resin, polyvinyl acetal, etc. is used. The primer composition may use a suitable solvent that does not affect the lens for the purpose of adjusting the viscosity of the composition. Of course, it may be used without a solvent. The primer layer can be formed by either a coating method or a dry method. When using the coating method, after applying the primer composition to the lens by a known coating method such as spin coating or dip coating, the primer layer is formed by solidifying it. When performing by the dry method, it is formed by a known dry method such as CVD method or vacuum deposition method. When forming the primer layer, for the purpose of improving the adhesion, the surface of the lens may be pretreated, such as alkali treatment, plasma treatment, ultraviolet treatment, etc., if necessary. The hard coat layer is a coating layer intended to impart functions such as scratch resistance, abrasion resistance, moisture resistance, hot water resistance, heat resistance, and weather resistance to the lens surface. Generally, the hard coat layer is composed of a curable organosilicon compound and one or more oxide fine particles of elements selected from the element group of Si, Al, Sn, Sb, Ta, Ce, La, Fe, Zn, W, Zr, In, and Ti and / or one or more fine particles composed of a composite oxide of two or more elements selected from these element groups. A hard coat composition containing them is used. In addition to the above components, the hard coat composition preferably contains at least one of amines, amino acids, metal acetylacetonate complexes, metal organic salts, perchloric acids, salts of perchloric acids, acids, metal chlorides, and polyfunctional epoxy compounds. An appropriate 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 coating method such as spin coating or dip coating and then curing it. Examples of the curing method include heat curing and curing by irradiation with energy rays such as ultraviolet rays and visible light. In order to suppress the generation of interference fringes, the refractive index of the hard coat layer preferably has a difference in refractive index from the lens in the range of ±0.1. The antireflection layer is usually formed on the hard coat layer as necessary. There are inorganic and organic types of antireflection layers. In the case of an inorganic type, inorganic oxides such as SiO ２ , TiO ２ are used and formed by a dry method such as vacuum evaporation, sputtering, ion plating, ion beam assist method, or CVD method. In the case of an organic type, a composition containing an organosilicon compound and silica-based fine particles having internal cavities is used and formed by a wet method. The antireflection layer can be single-layer or multilayer. When used as a single layer, it is preferably at least 0.1 or more lower in refractive index than that of the hard coat layer. To effectively exhibit the antireflection function, it is preferably a multilayer antireflection film. 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 films such as ZnO, TiO ２ , CeO ２ , Sb ２ O ５ , SnO ２ , ZrO ２ , Ta ２ O ５ etc. Examples of the low refractive index film include SiO ２ films etc. On the antireflection layer, an antifogging layer, an anti-contamination layer, and a water-repellent layer may be formed as necessary. As methods for forming the antifogging layer, the anti-contamination layer, and the water-repellent layer, as long as they do not have an adverse effect on the antireflection function, there are no particular limitations on the treatment method, treatment material, etc., and known antifogging treatment methods, anti-contamination treatment methods, water-repellent treatment methods, and materials can be used. For example, in the antifogging treatment method and the anti-contamination treatment method, there are methods such as covering the surface with a surfactant, adding a hydrophilic film to the surface to make it water-absorbent, covering the surface with fine irregularities to increase water absorption, using photocatalytic activity to make it water-absorbent, and performing super water-repellent treatment to prevent water droplets from adhering. Also, in the water-repellent treatment method, there are methods such as forming a water-repellent treatment layer by vapor deposition or sputtering of a fluorine-containing silane compound, or dissolving a fluorine-containing silane compound in a solvent and then coating to form a water-repellent treatment layer. [Plastic Polarizing Lens] The plastic polarizing lens of the present embodiment includes a polarizing film and a base material layer formed by curing the polymerizable composition for optical materials of the present embodiment on at least one surface of the polarizing film. The polarizing film in this embodiment can be composed of a thermoplastic resin. Examples of the thermoplastic resin include thermoplastic polyester, thermoplastic polycarbonate, thermoplastic polyolefin, and thermoplastic polyimide. From the viewpoints of water resistance, heat resistance, and moldability, thermoplastic polyester and thermoplastic polycarbonate are preferred, and thermoplastic polyester is more preferred. Examples of the thermoplastic polyester include polyethylene terephthalate, polyethylene naphthalate, and polybutylene terephthalate. From the viewpoints of water resistance, heat resistance, and moldability, polyethylene terephthalate is preferred. Specific examples of the polarizing film include a dichroic dye-containing thermoplastic polyester polarizing film, an iodine-containing polyvinyl alcohol polarizing film, and a dichroic dye-containing polyvinyl alcohol polarizing film. The polarizing film may be used after being heat-treated for drying and stabilization. Furthermore, in order to improve the adhesion with an acrylic resin, the polarizing film may be used after performing one or more pretreatment selected from primer coating treatment, chemical treatment (chemical liquid treatment such as gas or alkali), corona discharge treatment, plasma treatment, ultraviolet irradiation treatment, electron beam irradiation treatment, roughening treatment, and flame treatment. Among such pretreatment, one or more selected from primer coating treatment, chemical treatment, corona discharge treatment, and plasma treatment are particularly preferred. The plastic polarizing lens of this embodiment can be obtained by providing a base material layer obtained by curing the polymerizable composition for optical materials of this embodiment on at least one surface of such a polarizing film. The manufacturing method of the plastic polarizing lens is not particularly limited, but preferably, the casting polymerization method can be mentioned. The manufacturing method of the plastic polarizing lens of this embodiment is, for example, a step of fixing the polarizing film in a lens casting mold in a state separated from the mold, and A step of injecting the polymerizable composition for an optical material into at least one of the gaps formed between the polarizing film and the mold; A step of polymerizing and curing the polymerizable composition for an optical material to laminate a base material layer on at least one surface of the polarizing film, can be included. The mold for lens casting is generally composed of two substantially disk-shaped glass molds held by a gasket. A polarizing film is placed in the space of this mold for lens casting so that the film surface is parallel to the inner surface of the front mold where the film surfaces face each other. A gap is formed between the polarizing film and the mold. Note that the polarizing film may be pre-shaped. The polymerization conditions of the polymerizable composition for an optical material vary depending on the composition of the polymerizable composition, the type and amount of the catalyst, the shape of the mold, etc., but are carried out at a temperature of 5 to 140°C for 1 to 50 hours. In some cases, it is preferably cured in 1 to 25 hours by holding or gradually raising the temperature in the temperature range of 5 to 130°C. The laminate cured by polymerization can be released from the mold to obtain the plastic polarizing lens of the present embodiment. In the present embodiment, the laminate after polymerization and release may be subjected to heat treatment such as annealing as necessary. The treatment temperature is carried out between 90 and 150°C from the viewpoint of the effects of the present invention, preferably at 110 to 130°C, and more preferably at 115 to 125°C. The treatment time is in the range of 1 to 10 hours, preferably 2 to 5 hours, from the viewpoint of the effects of the present invention. Note that a coating layer similar to that of a plastic spectacle lens may be formed on the surface of the obtained base material layer. Next, the present invention will be described in more detail with reference to examples, but the present invention is not limited by these examples. In the examples and comparative examples, the methods and apparatuses used for evaluation are as follows. (Evaluation of the stability of photochromic performance (Accelerated test)) Using a QUV / SE accelerated weathering tester QUV manufactured by Q-Lab Corporation equipped with a UVA-340 type lamp, the irradiation intensity is 0.50 W / m ２、The acceleration test was carried out under the conditions of an irradiation time of 150 hours and a temperature of 50°C, and the dimming performance evaluation (light transmittance at the time of color development) before and after the acceleration was measured by the following method. The smaller the difference in transmittance before and after the acceleration test, the less the deterioration of the photochromic performance, and it can be judged that it is stable. (Dimming performance evaluation) Using a metal halide lamp (180W) light source device, at a temperature of 19°C and an ultraviolet intensity of 1.2 mW / cm measured by an integrating photometer ２ Under the conditions, the spectrum when a molded body sample processed to a thickness of 2.0 mm is colored for 5 minutes is measured by a transmission measurement system. ・Light transmittance at the time of color development: The light transmittance at 550 nm when colored under the above conditions When this value is small, the light-shielding property at the time of color development is high, and the photochromic performance is high. ・Light source: Metal halide light source device "LA-180ME" manufactured by Hayashi Watch Industry Co., Ltd. ・Integrating photometer: Integrating photometer "UIT-102 (light receiver UVD365PD)" manufactured by Ushio Inc. ・Transmission measurement system: "MV-3150" manufactured by JASCO Corporation (Analysis of residual functional groups by IR measurement) The IR spectrum of a resin sample cut and polished to a thickness of 0.35 mm was measured using an IR analyzer Spectrum One manufactured by PERKIN-ELMER. NCO is 2257 cm －１ , SH is 2550 cm －１ The absorbance was determined by the baseline method using the absorption at, and was determined by the calculation of the following formula from a calibration curve prepared in advance. [Comparative Example 1] To 41.0 parts by mass of 2,5(2,6)-bis(isocyanatomethyl)bicyclo[2.2.1]heptane, 0.05 part by mass of the compound of the formula (9) as a photochromic compound and 0.10 part by mass of dimethyltin dichloride were added, and the mixture was stirred and dissolved. To this mixed solution, 22.5 parts by mass of polypropylene glycol having a number average molecular weight of 700 and 36.5 parts by mass of pentaerythritol tetrakis(2-mercaptoacetate) were added and mixed and stirred. When each solution became uniform, it was degassed under 5 mmHg for 20 minutes, and these solutions were each injected into a polyethylene sheet mold. These were put into a furnace at 20 °C and kept for 8 hours, and then the temperature was raised to 120 °C over 12 hours. After heating at 120 °C as it was for 3 hours, the mold was taken out of the furnace, the mold was removed, and a molded body (a disk shape with a diameter of 45 mm and a thickness of 2.0 mm) obtained by polymerization was taken out. The molded body was colorless and transparent, had good light control performance of immediately coloring purple under sunlight and fading when the light was shielded. Next, the quantification of the residual -NCO groups and -SH groups of the molded body was carried out by IR analysis. Also, the light control performance of these molded bodies before and after the acceleration test was evaluated. These results are shown in Table 1. [Comparative Example 2, Examples 1 to 3] A molded body was prepared in the same manner as in Comparative Example 1 except that the addition amounts of 2,5(2,6)-bis(isocyanatomethyl)bicyclo[2.2.1]heptane, polypropylene glycol having a number average molecular weight of 700, and pentaerythritol tetrakis(2-mercaptoacetate) were changed as shown in Table 1. Each molded body was colorless and transparent, had good light control performance of immediately coloring purple under sunlight and fading when the light was shielded. Next, the quantification of the residual -NCO groups and -SH groups of these molded bodies was carried out by IR analysis. Also, the light control performance of these molded bodies before and after the acceleration test was evaluated. These results are shown in Table 1. From the results of Comparative Examples 1 and 2 described in Table 1, when the remaining amount of SH groups in the molded body increased to 1.0 wt% or more, the transmittance after the acceleration test increased significantly and the light control function was almost lost, and deterioration of the photochromic performance was observed. On the other hand, as in Examples 1 to 3, when the remaining amount of SH groups in the molded body was less than 1.0 wt%, the change amount of the transmittance was small, and it was confirmed that the photochromic performance was stable. In addition, it was presumed that similar results could be obtained for plastic polarizing lenses. This application claims the priority based on Japanese Patent Application No. 2015-183494 filed on September 16, 2015, and the priority based on Japanese Patent Application No. 2015-240357 filed on December 9, 2015, and incorporates the entire disclosure thereof herein.
