加工性、耐熱性、耐溶剤性に問題を残している。 Since the establishment of FDA standards in the United States in 1972, the safety of eyeglass lenses has been reviewed worldwide.
Synthetic resins have come to be used in place of inorganic glass. The shift from inorganic glass to synthetic resin lenses is a global trend, and even in Japan, lenses made of diethylene glycol bisallyl carbonate (product name CR-39, hereinafter abbreviated as CR-39) resin are gradually expanding their shear. It is said that it has already exceeded 20%. In addition to high safety (impact resistance), synthetic resin lenses have many advantages such as being lightweight, easy to process, and easy to dye. On the other hand, CR-39, which is the mainstream synthetic resin lens material, has a low refractive index of 150, which has the disadvantage of making the lens thicker, so there is a strong latent consumer demand for thin plastic lenses that are comfortable to wear. Furthermore, since polycarbonate, polystyrene, etc. having a relatively high refractive index are thermoplastic resins, there remain problems in beading processability, heat resistance, and solvent resistance.

成樹脂レンズが実現できるものである。 In view of this situation, a synthetic resin lens made of a thermosetting, high refractive index hard resin was proposed in JP-A-55-13747 and JP-A-56-166214. These synthetic resin lenses are made of a copolymer whose main components are one or more monomers whose general formula is represented by the formula [] and one or more monomers whose general formula is represented by the formula [], A synthetic resin lens with a refractive index of 1.60 or higher and excellent optical properties can be realized.

An integer of 5, n represents an integer of 0 to 3. ) However, such high refractive index synthetic resin lenses have the following drawbacks.

いという欠点を有している。 In other words, among the advantages of synthetic resin lenses mentioned above, the ease of dyeing has greatly contributed to the expansion of the market share of synthetic resin lenses, and currently
It is said that over 70% of CR-39 lenses are sold dyed. Therefore, it is no exaggeration to say that synthetic resin lenses that cannot be dyed have significantly inferior commercial value and will not have marketability in the future. The dyeing solutions used to dye lenses have the disadvantage that they cannot be dyed at all, or if they are dyed, they can only be dyed in spots, and cannot be dyed uniformly.

If the amount is less than 0.5g per 1 part of water, the lens will hardly be dyed, and if it exceeds 50g, the carrier will not be dispersed evenly and the lens will be easily dyed in spots, making uniform dyeing difficult. Become. If the amount of anionic surfactant is less than 0.2g per 1 part of water, depending on the type of surfactant, it becomes impossible to uniformly disperse the carrier and disperse dye, which tends to cause color unevenness of the dye body. If this is exceeded, not only will the dyeing solution become foamy, making it difficult to dye, but the dispersion effect will not improve. If the amount of disperse dye is less than 0.5 g, it will take time to dye, although it depends on the type of disperse dye, and if it exceeds 20 g, it will become difficult to disperse and will settle to the bottom of the liquid, increasing the concentration and eliminating the effect.

斑点状に染つたばかりでなく、境界線がはつきり
とでき、商点としての価値を持たなかつた。 For comparison, a dyeing solution containing no carrier and no surfactant was prepared and dyed in the same manner. Lenses containing no carrier were not dyed at all, and lenses containing no surfactant were dyed not only in spots like in Examples 1 and 2, but also with sharp border lines, making it difficult to use as a commercial point. It had no value.
