More specifically, the reactive dye-type dye compound of the contact lens of the present invention can be used to make color contact lens. Even after autoclave sterilization, the dye does not dissolve the dye compound from the lens and the dye compound. The manufacturer can be used to make colored soft contact lenses. A soft compound which can be covalently bonded to the soft compound and its manufacturing method. The reversed hydrophilic hydrophilic soft multiple autoclaving (Multiple will not cause discoloration, and [Previous technology] At present, many different processes have been used to make full-color or color vision lenses with different functionalities. Taking contact lens lenses as an example, full-color contact lenses can not only change the appearance of the user's iris Color, and because it has color, it is easy to tell where the lens is in the clear solution in the lens storage, disinfection, or cleaning container. Ik color 1¾-shaped spectacle lenses require color dyes. Generally, Color dyes can be added to the lens-forming material before or after polymerization In lenses, one of the conventional methods is to dissolve or disperse inorganic pigments (Inorganic pigments or organic dyes) in monomers (Monomer preCUrs) of uranium formed in the lenses. r) or polymer matrix. Inorganic pigments or long-chain organic dyes can be fixed in the lens later to reveal the desired color. However, this method is not suitable for hydrophilic softness. The coloration of 1233881-shaped spectacle lenses, because such lenses have high water content (Water content;), often lead to migration or dissolution of the colorant, resulting in color shift. It is commonly used in hydrophilic soft contact lenses During the process of high-pressure thermal sterilization of the lens, the migration or dissolution of this dye will be more serious. The method proposed in US Patent No. 4,252,421 is used on soft contact lens lenses. Water-insoluble dye to alleviate the problem of poor dyes. This lens is dyed with water-insoluble peptide Phthalocyanine The monomer forming the hydrophilic lens is completed by heat curing. Such peptide cyanine dyes, for example, copper peptide cyanocyanine (copper phthalocyanine). This peptide cyanine dye is fixed to the finished In lenses, it can still exist stably in an environment with a maximum moisture content of 35.7%. However, if 2-Hydroxyethyl methacrylate (HEMA) is used as the hydrophilic monomer (Hydrophilic monomer) And in an environment with a water content of 40%, the water-insoluble peptide cyanine dye will still be explained from the lens. To make matters worse, the problem explained by this solution will worsen as the proportion of water content rises. A method for preparing a full-color contact lens using a copper peptide cyanine pigment [Color Index (Pigment Blue 15)] is also disclosed in US Patent No. 6,149,842. The copper peptide The cyanine pigment was first dispersed in an aqueous solution. The aqueous solution was firstly added with polyvinyl alcohol (Pollyvinyl alcoho PVA) as a dispersing agent. Later, it was pioneered with Crosslinkable polyvinyl alcohol. The pVA is mixed in the mouth, and then photopolymerized (Photopolized) in the mold to form a lens. However, this patent does not disclose details of the efficacy of the dye used. 1233881. As described above In an environment with a large amount of water content, the dissolution of the dyes is still a potential problem that may occur with this method. US Patent No. 5,516,467 also discloses a similar concept, one of which is a Vat dye, such as a pigment Vat Biue 6 is first converted into a Leuco compound and dissolved in the hydrophilic N, N-Dimethyl acrylamide monomer to make A full-color monomer solution (Tintedm0mersomers), and then the solution and other ingredients are heated in a heated environment and polymerized to form a lens. The lens is then subjected to boiling water to dissolve the hidden Color body conversion becomes insoluble # Yao dye. Although this vat dye is non-covalently bonded to the lens forming material, it is also reported to have excellent stability and does not fade in boiling water for 200 hours. However, the disadvantage is that if it is located in a suitable test environment, the fixed vat dye can also be converted back to the dissolved leuco 'and' if in an acidic environment, the reaction of the dye is not uniform (Unevenly reacted) . Other methods of applying color to contact lens lenses are by printing (Transfer printing or Transfer printing) method, which is applied to the finished lens_L. Basically, the method is usually printed by silicone Second (SiliC〇n — μ㈣), transfer color solvent ink (Coloring ink port) to the lens. This type of transfer Fang Mugu Chu # m ^ There are disadvantages to the P method 'because this method cannot be used to dry the lens The surface of 'the toner will be - flawless closely spaced colored helmet many different parties.

Some pigments / soap suspensions were used. Distributing to the knitting device, this mold is used to print or print a specific shape or space between 1233881 and a traditional spin casting technology to form a full-color contact lens, as disclosed in US Patent No. 4,640,805. Although these improved methods can alleviate the phenomenon of Blemish defect ', because of the use of non-covalent bonding dyes, they all suffer from the potential risk of pigment migration during autoclaving. Therefore, in order to remove this disadvantage, a reactive color dye can be adapted to this need. Because it co-polymerizes with the lens material to form a covalent bond, the dye can be prevented from dissolving in the lens under different use environments. For example, U.S. Patent No. 5,352,245 discloses a reactive color dye, which is used to prepare transfer printing inks in order to compensate for the aforementioned migration problem (Migrati0I1 shortage). This patent uses a reactive color dye, such as: Ramazol Black B, together with polyvinyl pyrrolidone (PVP) base agent (Binder), and a non-ionic surfactant (Surf Actant) are mixed together to prepare an ink, which is then transferred to a hydrophilic contact lens to form a full-color contact lens lens having a desired pattern. After completing the subsequent test solution immersion procedure, the reactive dye can form a covalent bond with the lens material. However, the effectiveness of the full-color contact lens is still unresolved. In addition, this method is very complicated and has the general shortcomings of soaking-to-fix technology. Many patents, such as US Patent No. 4,559,059, US Patent No. 4,468,229, US Patent No. 4,157,892, US Patent No. 4,891,046, US Patent No. 4,553,975, US Patent No. 4,929,250, US Patent No. 5,292,350, US Patent No. 5,480,927 proposes a method for coloring the contact lens in full color, 1233881, which is a method of immersing a dye and a formed lens in an alkaline solution so as to form a chemical bond between the dye and the lens material. Such a reactive color dye 'may be mixed with the lens forming material mixture (Monomer mixtures) before the polymerization step, or added to the alkaline solution after the lens polymerization step. In addition to the different types of reactive color dyes and production procedures mentioned above, these patents are usually time-consuming and require multiple steps, such as Neutralization, Extraction, and The step of washing (rinsing) can be colored in the contact lens. In addition, the process variables of the above patents must be carefully controlled to avoid the occurrence of uneven dispersion and colorization. A number of patents have proposed more effective lens dyeing methods by first forming a conjugated bond between the monomer or prepolymer and the reactive color dye. 'Functi The prepolymer is introduced into a lens mold and cured. This method can effectively alleviate the process problems described in the aforementioned Soaking-to_fix method. The following patents, such as U.S. Patent No. 4,252,421, U.S. Patent No. 5,944,853, U.S. Patent No. 5,938,795, U.S. Patent No. 5,871,675, U.S. Patent No. 6,149,692 'U.S. Patent No. 4,795,794, and U.S. Patent No. 6 No. 162,844 'uses the aforementioned technique to chemically fix the dye to the lens forming material before the polymerization step. The main difference between these patents lies in the different types of reactive color dyes and precursors (Precursor). Although these patented methods have the advantages described, they still have the following shortcomings: ^ For example, tedious purification steps and premature discoloration caused by periodic door heat sterilization treatment 1233881 fading) The methods disclosed in patents often include one or more disadvantages. These shortcomings, such as' lengthy process time, low conversion (Low degi ^ e of cone), explanation of the dissolution of weakly-bonded dyes, fading, inconsistent lens shades, reaction with various items or purification process. Because of &, a method for preparing colored contact lens lenses having excellent coloring stability 'but not having the aforementioned disadvantages, and a method of manufacturing colored contact lens lenses with this dye' is extremely industrially desirable. [Summary of the Invention] One of the objectives of the present invention is to provide a reactive dye-monomer compound (ReacUve dye-monomer compound), which can be used to prepare color lenses. The dye-monomer compound contains at least one An absorbing moiety) and an unsatwated vinyl group. This compound is highly reactive. It can be covalently bonded to the lens material through a polymerization process. Another object of the present invention is to provide a method for producing a reactive dye-monomer compound, which can be used for producing a color lens. By this method, a novel reactive dye-monomer compound can be obtained. The monofunctional functional dye-monomer compound prepared by this manufacturing method early has high purity and high reactivity. Another object of the present invention is to provide a method for manufacturing a colored contact lens using a reactive dye-monomer compound, so that the reactive dye is colored in a lens. According to this method, a reactive dye 10 1233881 material-monomer compound is mixed with a lens forming material, and the mixture is cured on a lens mold to prepare a full-color soft contact lens. This method does not require tedious cleaning and development steps to obtain the uniformly colored full-color lens. Another object of the present invention is to provide a colored contact lens manufactured by using a reactive dye-monomer compound. The dyeing lens has excellent coloring properties and is subjected to multiple autoclave sterilization treatment. After that, the problem of premature fading does not occur. This exceptional durability is because the dye-monomer compound can form a covalent bond with the lens-forming material upon curing, and the polymer chain has excellent stability at high temperatures.
