A6 B6 SI1914 V. Description of the invention (/) (Please read the precautions on the back before filling in this page) The present invention has the manufacturing methods of glasses, eyes, mirrors and diallyl phthalate oligomers (diallyl phthalate type oligomer) in glasses. Recently, plexiglass has begun to replace inorganic glass for optical components, such as windows, tinctures, cameras, TV screens, telescopes, and glasses. Ophthalmic lenses include corrective lenses as well as non-corrective lenses, for example, sunglasses. Plexiglass has several advantages, including lighter weight and safer than inorganic glass. Traditionally, materials used for organic glass include polystyrene resin, polymethyl methacrylate resin, and polyester resin. However, these polymers have their own disadvantages. For example, polymethacrylate resins are prone to high moisture absorption and change their shape and refractive index. In addition, polystyrene resins and polyester resins have the following defects: birefringence, light scattering, and loss of transparency over time. Furthermore, both polymethyl methacrylate and polystyrene are neither scratch resistant nor solvent resistant. · Plexylallyl carb ο nate 〇f ρ ο 1 yhydr ο X ya 1 c ο Ιι ο 1 s prepared by radical polymerization of organic glass products are also known For example, those mentioned in EP — A —, 0 473163. This polymer does not have the above problems. It is printed by the Industrial and Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. However, when polyhydric alcohol poly (5heptanoate) is used in eyeglasses, two other problems often occur, namely, coloring failure and prerelease in the mold. Coloring glasses, Including corrective mirrors and non-corrective mirrors (eg, sunglasses) -4- This paper is used again in the 0 national express (CNS) A 4 standard (210 X 297 public goods) 82.6. 40,000 311914 A6 B6 in the Ministry of Economy Printed by the β Bureau of Standards and Consumers Cooperatives of the Bureau of Standards 5. Description of the invention (1) Both of them are almost entirely advantageous in preparation. The surface dip dyeing method is used to immerse the glasses in the aqueous dispersion of the dye. However, glasses made with polyhydric alcohol poly (allyl monoester) often exhibit uneven surface coloration in the form of an arc. This coloring failure in colored glasses can be caused by being unsuitable as a commercial product. The finished lens has a large proportion of retreat. Pre-release or pre-release in the mold is the phenomenon that the poured glasses loosen from the surface of the mold during polymerization. In this way, the failure will occur on the surface of the lens This lens can't be used without correction by grinding and / or polishing. This pre-release phenomenon is particularly noticeable in the production of finished lenses with polyhydric alcohol allyl esters The finished lens M (finished lens) is a corrective lens whose final shape depends on the size of the mold. Therefore, after the lens is taken out of the mold, it should have the correct curvature and magnification without subsequent processing. Because there is no post Rigorous processing steps to correct the defects of the lens, therefore, it is required that the polymer casting product of the finished lens must meet the specifications of the end product. The polyhydroxy · alcohol (allyl sulfonate) is used to manufacture the finished lens At the time, because of the pre-release phenomenon that occurred in the polymerization casting, it led to the situation that up to 70% of the finished lens was returned. Although not wanting to be bound by any theory, it is still believed to be due to polyhydroxy alcohol The common shrinkage of propylene carbonate leads to pre-release. For example, diethylene glycol diallyl carbonate (diethylene glycol diallyl carbonate) shrinks by 14% during polymerization, see Kirk Othaer, Encyclopedia of Chemical Technology (Encyclopedia of (please read the precautions on the back before filling in this page) • Binding and Ordering.

Therefore, the pre-release of the finished lens may be the result of shrinkage during polymerization casting. More specifically, because the thickness of the finished mirror H varies widely from the edge to the center of the mirror H, the amount of shrinkage also varies widely and thus pre-release of the finished lens often occurs. Therefore, the problem of pre-release must be solved. One method to prevent premature release is to use an adhesion promoter (adhe s i ο η p r 〇 m 〇 t 〇 r) in polyhydric alcohols such as allyl oleate. Examples of such adhesion promoters are silane and maleic anhydride. However, this method cannot significantly reduce the pre-release phenomenon. Furthermore, the adhesion promoter will increase the adhesion to the glass mold, resulting in a higher mold damage rate. In summary, the initial goal of the present invention is to propose a pair of glasses that can be colored evenly. Another object of the present invention is to propose a pair of glasses that can be made under the lowest pre-release type, so that the glasses, especially the returned lenses of the finished lenses, are again applicable to China National Standard (CNS) A4 (210 X 4.7 public goods) 82.6. 40,000 ----------------- {------ installed ------- order ------ {.

Moreover, the eyeglasses of the present invention, especially the finished lenses, have a reduced premature phenomenon during polymerization casting, so the rejection rate in production is significantly reduced. The glasses of the present invention need to have a refractive index of 1.5 to 1.51. More particularly, the molds used in the industry of preparing allyl alcohol esters of polyhydric alcohols (refractive index = 1.498) today are only suitable for compositions that can produce glasses with similar refractive indices. When the index of refraction is moved, the same model will be used, which will cause the lens magnification to change. To produce high-refractive-index lenses, the composition used must use different molds to obtain glasses with the same magnification. Therefore, there is no way to improve the properties of the lens by introducing a certain oligomeric substance and optionally selected comonomers without limiting the refractive index of the resulting lens so as not to change the mold.

The composition can be used in optical components such as high-refractive-index lenses. According to its description, the cured composition based solely on diethylene glycol diallyl master ester has a too low refractive index, resulting in thick lenses that require significant correction. In addition, cured compositions containing less than 10% by weight of diallyl phthalate oligomers also have poor impact resistance and poor heat resistance. Furthermore, the application does not mention the advantages of improving color rendering or reducing the pre-release phenomenon of the wax. Therefore, the present invention is not disclosed by the JPO 1 3992 18.
