Description
本発明は、高い屈折率及び高い透明性が要求される光学材料等の樹脂分野に好適に使用される硫黄原子含有樹脂材料、特にエピスルフィド系硫黄原子含有樹脂材料に関する。 The present invention relates to a sulfur atom-containing resin material, particularly an episulfide-based sulfur atom-containing resin material, which is suitably used in the resin field such as an optical material that requires a high refractive index and high transparency.
プラスチックレンズは、無機レンズに比べ軽量で割れ難く、染色が可能なため近年、眼鏡レンズ、カメラレンズ等の光学素子に急速に普及してきている。
これらプラスチックレンズに要求され続けている性能は光学性能としては高屈折率、高アッベ数、物理的性質としては高耐熱性、高耐衝撃性、低比重である。
In recent years, plastic lenses are rapidly spreading to optical elements such as spectacle lenses and camera lenses because they are lighter and harder to break than inorganic lenses and can be dyed.
The performance required for these plastic lenses is high refractive index and high Abbe number as optical performance, and high heat resistance, high impact resistance and low specific gravity as physical properties.
現在、これらの要求性能をある程度満足した樹脂としては、樹脂中に硫黄原子を導入した、ポリチオウレタン樹脂が知られている。ポリチオウレタン樹脂は、高屈折率で耐衝撃性が良好である等、バランスの優れた樹脂である(例えば、特許文献1、特許文献2参照)。 Currently, polythiourethane resins in which sulfur atoms are introduced into the resin are known as resins that satisfy these required performances to some extent. The polythiourethane resin is a resin having an excellent balance such as high refractive index and good impact resistance (see, for example, Patent Document 1 and Patent Document 2).
また、更なる高屈折率化、高アッベ数化の要求に対して、ポリチオウレタンに使用するポリチオール化合物の硫黄含有率を向上させる手法も提案されている(例えば、特許文献3、特許文献4、特許文献5、特許文献6)。 Further, in response to demands for higher refractive index and higher Abbe number, methods for improving the sulfur content of polythiol compounds used in polythiourethanes have also been proposed (for example, Patent Document 3 and Patent Document 4). Patent Document 5, Patent Document 6).
一方、耐衝撃性などの強度に関する要求物性は満足しないものの、高屈折率、高アッベ数を追求した素材として、エピスルフィド化合物を使用する方法も提案されている。(例えば、特許文献7、特許文献8参照)
これら特許文献の方法によれば、高屈折率・高アッベ数・低比重などのプラスチックレンズとしての優れた性能を実現可能である。しかしながら、これらの方法で得られた樹脂や、それからなるプラスチックレンズにおいては、洗浄や染色、コーティング、研磨などの後工程を経るにつれ、例えば、レンズの強度が低下してしまう場合があり、レンズ製造における品質低下の一因となっていた。特に、強度の絶対値が比較的小さいエピスルフィド系の樹脂およびそれからなるレンズについては、強度低下の影響は深刻である。そこで、この後工程での強度低下が小さく、その結果品質低下が起きにくい、性能の高いエピスルフィド系のプラスチックレンズ基材の開発が求められてきた。 According to the methods of these patent documents, excellent performance as a plastic lens such as a high refractive index, a high Abbe number, and a low specific gravity can be realized. However, in the resin obtained by these methods and plastic lenses made from the resin, the strength of the lens may decrease, for example, as it undergoes subsequent processes such as washing, dyeing, coating, and polishing. Contributed to the decline in quality. In particular, with respect to an episulfide resin having a relatively small absolute value of strength and a lens comprising the same, the influence of the strength reduction is serious. Accordingly, there has been a demand for the development of a high-performance episulfide-based plastic lens base material in which the strength reduction in the post-process is small, and as a result, quality degradation is unlikely to occur.
本発明者らは、上述の課題を解決するために樹脂の諸物性に着目して鋭意検討した結果、JIS K7209に従い測定した、温度25℃、24時間での樹脂の吸水率が0.01%未満であるエピスルフィド系硫黄原子含有樹脂からなる材料が、後工程でのレンズ強度低下が小さい、優れた光学材料であることを見出し本発明に至った。 As a result of diligent study paying attention to various physical properties of the resin in order to solve the above-mentioned problems, the water absorption rate of the resin at a temperature of 25 ° C. and 24 hours measured by JIS K7209 is 0.01%. It has been found that a material composed of an episulfide-based sulfur atom-containing resin, which is less than 1, is an excellent optical material with a small decrease in lens strength in the subsequent step, and has led to the present invention.
即ち、本発明は、
[1]エピスルフィド化合物とポリチオール化合物とを含む重合性組成物を重合して得られるエピスルフィド系硫黄原子含有樹脂からなる光学材料の後処理後の強度低下を抑制する方法であって、前記樹脂としてJIS K7209に従い測定した、温度25℃、24時間での吸水率が0.01%未満0.0010%以上の樹脂を使用することを特徴とする方法に関する。なお、本発明において、「エピスルフィド系硫黄原子含有樹脂からなる」とは、当該光学材料の一部が当該エピスルフィド系硫黄原子含有樹脂で構成されている場合、および、当該光学材料の全部が当該エピスルフィド系硫黄原子含有樹脂で構成されている場合、の双方を含む趣旨である。

例えば、樹脂を構成する高分子鎖の構造を限定することで、樹脂の吸水率を適宜増減することができる。より具体的には、本発明におけるエピスルフィド系硫黄原子含有樹脂においては、樹脂中に存在する硫黄原子の含有率を増減することで、樹脂の吸水率を増減することができる。エピスルフィド系硫黄原子含有樹脂中の硫黄の含有率が増加すれば当該樹脂の吸水率は低下する傾向があり、硫黄の含有率が減少すれば吸水率は増加する傾向がある。 For example, by limiting the structure of the polymer chain constituting the resin, the water absorption rate of the resin can be appropriately increased or decreased. More specifically, in the episulfide-based sulfur atom-containing resin in the present invention, the water absorption rate of the resin can be increased or decreased by increasing or decreasing the content of sulfur atoms present in the resin. If the sulfur content in the episulfide sulfur atom-containing resin increases, the water absorption rate of the resin tends to decrease, and if the sulfur content decreases, the water absorption rate tends to increase.
本発明の実施例にあるようなジチオアセタール骨格またはジチオケタール骨格を有するエピスルフィド化合物を用いる材料系では、その吸水率を0.01%未満とするためには、樹脂改質剤等の添加剤の影響によっても変動しうるものの、通常、
樹脂中に存在する硫黄原子の含有率が40重量%以上となるように、樹脂を構成するモノマー原料の化合物および混合比を選択するとよい。45重量%以上であればより好ましく、50重量%以上であれば更に好ましい。所望の吸水率を与える好ましい硫黄原子の含有率は材料系によって異なるが、従来公知のデータおよび/または比較的簡単な実験によって決定することができる。
In a material system using an episulfide compound having a dithioacetal skeleton or a dithioketal skeleton as in the examples of the present invention, in order to reduce the water absorption to less than 0.01%, the influence of additives such as a resin modifier Can vary, but usually
It is advisable to select the monomer raw material compound and the mixing ratio of the resin so that the content of sulfur atoms present in the resin is 40% by weight or more. It is more preferably 45% by weight or more, and further preferably 50% by weight or more. The preferred sulfur atom content that gives the desired water absorption depends on the material system, but can be determined by conventionally known data and / or relatively simple experiments.
また。樹脂の吸水率は、後述のような各種樹脂改質剤の添加によっても適宜調整することができる。 Also. The water absorption rate of the resin can be appropriately adjusted by adding various resin modifiers as described below.
上述のように、後工程におけるレンズの強度低下を抑制する観点からは、樹脂の吸水率が低いことが好ましいが、吸水率が著しく低いと、染色が困難になったり、長時間を要したりする場合がある。染色の容易さの観点からは、樹脂の吸水率は、通常0.0010%以上、好ましくは0.0012%以上、さらに好ましくは0.0015%以上であることが望ましい。 As described above, from the viewpoint of suppressing a decrease in the strength of the lens in the post-process, it is preferable that the water absorption rate of the resin is low. There is a case. From the viewpoint of ease of dyeing, the water absorption rate of the resin is usually 0.0010% or more, preferably 0.0012% or more, and more preferably 0.0015% or more.
続いて、本発明におけるエピスルフィド系硫黄原子含有樹脂光学材料について記載する。本発明における硫黄原子含有樹脂とは、高分子鎖中に硫黄原子が導入されているものであり、スルフィド結合やジスルフィド結合、チオウレタン結合やチオエステル結合等の高分子鎖中に硫黄原子を有する樹脂のことを意味する。また、本発明の場合、高分子鎖中に硫黄原子を有さなくとも、硫黄が溶解した状態で樹脂中に存在するものも硫黄原子含有樹脂として取り扱う。このような硫黄原子含有樹脂の中でも、本発明におけるエピスルフィド系硫黄原子含有樹脂については、原料化合物の主成分或いは副成分としてエピスルフィド系化合物を使用していることが必須である。 Subsequently, the episulfide sulfur atom-containing resin optical material in the present invention will be described. The sulfur atom-containing resin in the present invention is a resin in which a sulfur atom is introduced into a polymer chain, and a resin having a sulfur atom in a polymer chain such as a sulfide bond, a disulfide bond, a thiourethane bond or a thioester bond. Means that. In the case of the present invention, even if the polymer chain does not have a sulfur atom, a resin which is present in the resin in a state where sulfur is dissolved is also treated as a sulfur atom-containing resin. Among such sulfur atom-containing resins, it is essential that the episulfide-based sulfur atom-containing resin in the present invention uses an episulfide-based compound as the main component or subcomponent of the raw material compound.
