Definitions

  • the present invention relates to a method of producing a dyed optical component to be used as sunglasses, spectacle lenses, or others.
  • a Plano lens a lens having no diopter
  • a semi-finished lens a convex surface side to form a lens front surface has a predetermined optic surface and a concave surface side to form a lens rear surface is a simple concave surface that will be formed as an optic surface later by cutting. This concave surface is then appropriately cut or machined to obtain a desired diopter.
  • the concave surface of the semi-finished lens is first subjected to a machining (cutting) work to have a required diopter, and the lens is immersed and dyed in a dye solution and then subjected to a hard coat treatment for lens protection (JP 2000-288891A).
  • the semi-finished lens When a dyed finished lens is to be produced from the semi-finished lens as explained above, the semi-finished lens has to undergo the machining work and then the dyeing work. It therefore takes long to produce the dyed finished lens. It is also conceivable to dye the semi-finished lens in a predetermined color in advance to shorten the dyeing process and store such lens. The concave surface of the semi-finished lens is shaved or cut away, resulting in a change in color density.
  • the hard coat In the case of applying a hard coat on the dyed semi-finished lens, the hard coat less easily adheres to a dyed surface. Particularly, the problems with adhesion and dye-affinity of the hard coat with respect to the dyed surface are important when polycarbonate is used as a lens material. Furthermore, the Plano lens, the semi-finished lens, and other lenses of such type are often mass-produced and carried in stock and also selectable dyeing patterns often have been determined in advance in order to be offered at as low a price as possible.
  • the present invention has been made in view of the circumstances to solve the above problems and has a purpose to provide a method of efficiently producing a dyed optical component from an optical component having been mass-produced such as a semi-finished lens and a Plano lens, the method being able to appropriately adhere a hard coat to a surface of the optical component.
  • one aspect of the invention provides a method of producing a dyed optical component, comprising: a first step of dyeing one surface of a film made of transparent resin to produce a dyed film; and a second step of setting the dyed film in a predetermined mold and injecting the thermoplastic resin melted by heat into the mold in which the dyed film has been set to produce a dyed optical component integrally including the dyed film by film insert molding, the dyed film being set in the mold to make a dyed surface of the dyed film contact with the melted thermoplastic resin.
  • FIG. 1 is a view showing a structure of a dyed semi-finished lens with a hard coat in an embodiment
  • FIG. 2 is a schematic view schematically showing a process of a vapor deposition transfer dyeing method used in the embodiment.
  • FIG. 3 is a view showing a modified example of the embodiment.
  • FIG. 1 is a view showing a structure of a semi-finished lens as a dyed optical component in this embodiment.
  • a dyed semi-finished lens 10 includes a semi-finished lens 1 having a spherical or aspheric optical surface in a front surface (a convex surface) and a simply concave surface in a rear surface, the concave surface being to be machined later, and a dyed film 2 joined to the front surface of the semi-finished lens 1 .
  • a joining surface of the film 2 that contacts with the semi-finished lens 1 has a dyed layer 3 dyed in a desired color.
  • a hard coat layer 4 for the purpose of surface protection. If the semi-finished lens does not need the surface protection, the hard coat layer 4 does not always have to be formed.
  • the hard coat layer 4 may be a hard coat single layer or be configured in a double layer including a primer coat for enhancing adhesion and a hard coat formed on the primer coat.
  • a conventionally known thermoplastic resin may be adopted.
  • polycarbonate, polyamide, polyurethane, polystyrene, acrylic resin, and others are selectable.
  • the film 2 has only to be made of a transparent resin heretofore known and available for film insert molding.
  • the film 2 is made of the same material as that used for the semi-finished lens 1 or a resin having a refractive index (power) approximate to that of the lens material forming the semi-finished lens 1 .
  • the aforementioned materials and polyethylene terephthalate can be used.
  • the film 2 may be configured not only in a single film form but also in a laminated film form including two or more films bonded to each other.
  • the thickness of the film 2 is determined to be able to be so softened by heat as to firmly adhere to a metal mold. It is preferably 0.005 mm to 5 mm and more preferably 0.1 mm to 1 mm. If the thickness of the film 2 is thinner than 0.005 mm, the film 2 is likely to constrict or the like by heat.
  • the hard coat layer 4 formed on the front surface of the film 2 is made of a conventionally known ultraviolet curing or thermosetting hard coat solution such as an acrylic solution and a silicone solution (a siloxane solution).
  • a conventionally known method such as a brush coating technique and a spin coating technique and is subjected to a curing treatment.
  • the rear surface (a surface to be joined with the semi-finished lens) of the film 2 is first dyed.
  • the dyeing method is not particularly limited as long as it is able to dye the film 2 .
  • a vapor deposition transfer dyeing method is appropriately used.
  • FIG. 2 is a schematic view schematically showing a process of the vapor transfer dyeing method.
  • vapor deposition transfer dyeing inks Three kinds (Red, Blue, and Yellow) of vapor deposition transfer dyeing inks are individually filled in ink cartridges 41 of a commercially available inkjet printer.
  • the cartridges filled with the inks are mounted in an inkjet printer 40 (hereinafter, referred to as a “printer”) not shown.
  • a commercially available printer may be used as the printer 40 in this embodiment.
  • dyes used for the vapor deposition transfer dyeing inks sublimable dyes such as quinophthalone dyes and anthraquinon dyes are appropriately used.
  • hue and density of the inks to be printed on a base body are adjusted by use of a personal computer (hereinafter, referred to as a PC) 50 .
  • the hue adjustment is made by a drawing software in the PC 50 .
  • desired color data can be stored in the PC 50 and the same color tone can be obtained as many times as it is needed.
  • color shade (contrast) is also digital-controlled and thus the color with the same density can be produced as many times as it is needed.
  • the base body on which the sublimable dye is to be printed is not particularly limited as long as it is usable in the printer 40 .
  • a commercially-available A4 paper is usable. Since the base body is heated during the vapor deposition transfer, a base body exhibiting good heat absorbing properties is preferably used.
  • the PC 50 is operated to print on the base body 100 in previously selected hue and density.
  • the base body 100 has a printed colored layer 100 a formed of the dyeing inks (the sublimable dyes).
  • the size of the colored layer 100 a is preferably determined to be slightly larger than the outer shape of the film 2 to be used.
  • the film 2 is dyed according to the vapor deposition transfer dyeing method by using the base body 100 on which the dyeing inks have been applied.
  • This vapor deposition transfer dyeing method is to dye a film by heating the base body 100 applied with the sublimable dyes in a vacuum atmosphere to thereby sublimate the sublimable dyes to deposit on the film placed to face the base body, and heating the film at a predetermined temperature to fix the dyes.
  • the base body 100 applied with the dyeing inks and the film 2 are placed in a vacuum vapor-deposition transfer machine body 20 , and the sublimable dyes contained in the dyeing inks are vaporized.
  • the front side of the machine body 20 has a port not shown through which the base body 100 and the film 2 are taken in and out.
  • a halogen lamp 21 is placed in the machine body 20 and used to heat the base body 100 in non-contact relation.
  • a rotary pump 22 is used to create an almost vacuum in the machine body 20 .
  • a leak valve 23 is to admit outside air in the machine body 20 to return the vacuum to atmospheric pressure.
  • a jig 30 is configured to set therein the base body 100 and the film 2 .
  • This jig 30 includes a film holder for holding the film 2 , and a base body holder for holding the base body 100 at a predetermined interval from the film 2 .
  • a to-be-dyed surface of the film 2 and a surface of the base body 100 on the colored layer 100 a side face each other in non-contact relation.
  • the machine body 20 is sealed and evacuated to create a vacuum by the rotary pump 22 .
  • the halogen lamp 21 When the vacuum in the machine body 20 reaches a predetermined level, the halogen lamp 21 is turned on to heat the base body 100 from above in non-contact relation.
  • a heating temperature of the base body 100 is determined to be as high as possible in a range causing no degradation of the dyes and deformation of the film 2 .
  • the base body 100 Since the base body 100 is heated by turn-on of the halogen lamp 21 , the dyes sublimate and evaporate from the colored layer 100 a and deposit on the to-be-dyed surface of the film 2 . Heating of the base body 100 by turn-on of the halogen lamp 21 has only to be continued until almost all the dyes on the colored layer 100 a evaporate.
  • the halogen lamp 21 is turned off. Thereafter, the leak valve 23 is opened to return the internal pressure of the machine body 20 to normal pressure and then the film 2 with the dyes deposited thereon is taken out.
  • the sublimated dyes have been deposited on the film 2 but those dyes in this state are liable to come off the film 2 . Accordingly, the film 2 is put in an oven 60 and heated at normal pressure to fix the dyes on the film 2 .
  • This process is performed through the steps of heating the inside of the oven at a temperature set to be as high as possible below an allowable temperature limit of the film 2 , and taking the film 2 out of the oven 60 after a lapse of a predetermined time required to obtain desired hue and density.
  • the heating temperature of the oven 60 is preferably set to be as high as possible in a range that does not cause degradation of the dyes and deformation of the film.
  • the heating temperature is about 50° C. to about 150° C.
  • a semi-finished lens joined with the dyed film 2 is produced by film insert molding.
  • the dyed film 2 is set in a mold for semi-finished lens molding and then the lens material melted by heat is injected into the mold to unite the film 2 and the lens material.
  • a metal mold is used as the mold but not limited thereto. Any molds usable in the film insert molding can be used.
  • the film 2 is subjected in advance to cutting and punching to have almost the same diameter and the same shape as those of the lens front surface.
  • a wall surface for forming the lens front surface (the convex surface) is previously designed to form a predetermined optic surface.
  • a wall surface of the metal mold for forming the lens rear surface (the concave surface) is designed to form a simple curved surface having no optic surface that determines the lens diopter.
  • the opposite surface of the film 2 from the dyed layer is placed in close contact with the wall surface of the metal mold to form the lens front surface.
  • the film 2 is heated in advance and the softened film 2 is brought in close contact with the wall surface of the metal mold by utilizing aspiration of air.
  • the thermoplastic lens material is poured into the metal mold and cured.
  • the produced dyed semi-finished lens includes the film 2 integrally joined to the lens front surface so that an undyed surface of the film 2 is placed as the frontmost surface of the lens.
  • the undyed surface of the film 2 is the lens (the dyed semi-finished lens) front surface. Even when a hard coat having high abrasion resistance is applied on the lens front surface, that coat layer is unlikely to come off. Thus, a dyed semi-finished lens with an appropriate hard coat can be produced.
  • the film used in this embodiment is a film having no optical function but not limited thereto.
  • a polarizing film may be used.
  • the film insert molding is conducted to join the dyed film 2 to the lens front surface but not limited thereto. For instance, the film insert molding may be performed to place a dyed film inside a semi-finished lens as shown in FIG. 3 .
  • the film is dyed in a desired color according to the vapor deposition transfer dyeing method but not limited thereto. Any methods capable of appropriately dyeing only one surface of a film may be adopted. For instance, only one surface of the film can be dyed in such a way that the other surface of the film is covered with a mask and then the film is immersed in a dye solution.
  • polycarbonate is a material very hard to dye and can hardly be dyed by normal immersion into the dye solution.
  • the aforementioned vapor deposition transfer dyeing method is particularly effective to dye the film.
  • the present embodiment exemplifies the semi-finished lens
  • the present invention is not limited thereto and may be applied particularly appropriately to dyed optical components that can be previously prepared in large numbers in stock, e.g., a lens having no diopter (a Plano lens) used as sunglasses.

  • output quantities of red, blue, and yellow inks were set to 44%, 70%, and 88% respectively.
  • an A4-size paper was printed by the printer.
  • the inks used in this example were Red NK-1, Yellow NK-2, and Blue NK-3 each containing anthraquinon dye and being produced by Nidek Co., Ltd.

  • the dyed film was punched out into a circular shape with a diameter of 78 mm. Then, the circular dyed film was placed in close contact with the wall surface of the metal mold corresponding to a lens convex surface side so that an undyed surface of the film contact with the wall surface of the metal mold. Successively, a lens material, polycarbonate, was injected into the metal mold for insert molding to produce a semi-finished lens in which the dyed film was joined to the lens front surface.
