DETAILED DESCRIPTION An example of a form for carrying out a lens dyeing substrate packing material, a lens dyeing substrate packing member, a lens dyeing substrate packing method, and a lens dyeing method according to the present disclosure will be described with reference to the drawings. FIGS. 1 to 6 are views for explaining a lens dyeing substrate packing material, a lens dyeing substrate packing member, and a lens dyeing base packing method according to this embodiment.

<Overview>
In the present embodiment, description will be made by taking a lens dyeing substrate package as an example. Of course, the technology according to the present disclosure can also be applied to a lens dyeing substrate packing member, a lens dyeing substrate packing method, and a lens dyeing method. A lens dyeing substrate package 20 according to the present embodiment includes a substrate (lens dyeing substrate) 1 to which a lens dyeing dye is attached, and a lens dyeing substrate packing member for packing the lens dyeing substrate 1. 21.

For example, the substrate 2 in the lens dyeing substrate 1 is made of paper, metal, glass or the like. For example, the lens dyeing substrate packing member 21 may be a bag, a container, or the like. For example, the lens dyeing substrate packing member 21 includes a change suppression unit 23 and a dye transfer suppression unit 24.

For example, the change suppression unit 23 suppresses a change in the dye of the substrate. For example, the change suppression unit 23 includes a metal part for blocking ultraviolet rays in order to suppress a change in the dye of the lens dyeing substrate 1. For example, examples of the metal part include aluminum, nickel, iron, copper, silver, gold, and stainless steel. Of course, the change suppression unit 23 is not limited to a metal part for blocking ultraviolet rays. The change suppression unit 23 only needs to have ultraviolet blocking properties. For example, a filter that blocks ultraviolet rays, a polyimide sheet, and the like are used.

For example, the dye transfer suppression unit 24 suppresses the dye of the lens dyeing substrate 1 from being transferred inside the lens dyeing substrate packing member 21. For example, the dye transfer suppression unit 24 includes at least polypropylene. Of course, the dye transfer suppression unit 24 may have any dye transfer suppressing property so as to prevent the dye of the lens dyeing substrate 1 from being transferred inside the lens dyeing substrate packing member 21. For example, the dye transfer suppression unit 24 may include at least polyethylene.

In addition, for example, the lens dyeing substrate package 20 may further include at least a gas portion S between the dye transfer suppressing unit 24 and the lens dyeing substrate 1. For example, as for the gas part S, air, nitrogen, etc. are mentioned. As described above, the lens dyeing substrate package 20 includes the gas portion S, so that the lens dyeing substrate 1 and the lens dyeing substrate packing can be applied even when pressure is applied in a state where the lens dyeing substrate 1 is packed. A space is formed between the members 21. For this reason, the lens dyeing substrate packing member 21 is less strongly pressed against the lens dyeing substrate 1, and the dye is hardly transferred to the lens dyeing substrate packing member 21.

Further, for example, the lens dyeing substrate package 20 may further include a shape maintaining member 25 for maintaining the shape of the lens dyeing substrate 1. For example, the shape maintaining member 25 may be a slip sheet, a template, or the like. As described above, the lens dyeing substrate package 20 includes the shape maintaining member 25, whereby the shape of the lens dyeing substrate 1 can be maintained. Further, it is possible to suppress the dye from being transferred to the lens dyeing substrate packing member 21.

In the present embodiment, at least two lens staining substrates 1 are packaged in the lens staining substrate package 20. Of course, the lens dyeing substrate 1 to be packed may be one.

For example, in the present embodiment, when the lens dyeing base 1 is packed, the plurality of lens dyeing bases 1 are packed with the surface on which the dye for dyeing the lens is attached directed in the same direction. You may do it. By packaging in this way, mixing of the dyes between the different lens dyeing substrates 1 when the lens dyeing substrates 1 are being sent is suppressed. This suppresses the occurrence of color unevenness or a different color when the lens is dyed.

For example, in the present embodiment, when the lens dyeing base 1 is packed, the lens dyeing dye attached to each of the plurality of lens dyeing bases 1 may be packed so as to have the same color. Good. By packing in this way, mixing of dyes between different lens dyeing substrates 1 can be suppressed. For this reason, when the lens is dyed, the occurrence of color unevenness or a different color is suppressed.

For example, the lens dyeing substrate package 20 in which the lens dyeing substrate 1 is packed is sent to a lens dyeing destination (seller) that dyes the lens. At the sales destination, the lens dyeing substrate package 20 that has been sent is opened, and the lens dyeing substrate 1 is taken out. When the lens dyeing substrate 1 is disposed facing the lens and the lens dyeing substrate 1 is heated, the dye attached to the lens dyeing substrate 1 is sublimated, and the dye is deposited on the lens. The dye-deposited lens is heated by heating the lens on which the dye is deposited. As described above, the lens is dyed at the sales destination.

In this way, by sending the lens dyeing substrate package 20 in which the lens dyeing substrate 1 is packed to the seller, it is possible to save time and labor for creating the lens dyeing substrate 1 at the seller. As a result, since the dyeing substrate 1 is prepared by a vendor, it is possible to suppress variation in the amount of the dye for dyeing the lens, and when performing lens dyeing using the lens dyeing substrate 1, Desired dyeing can be performed.

In addition, since the lens dyeing substrate packing member 21 includes the dye transfer suppression unit 24, the lens dyeing substrate 1 to which the lens dyeing dye is attached is dyed while being sent to the sales destination. It is possible to prevent the ink for use from being transferred to the packing member. For this reason, the lens dyeing | staining base | substrate 1 to which the dye for dyeing | staining of a lens was adhered is sent favorable.

<Example>
In the following, one exemplary embodiment will be described with reference to the drawings. FIG. 1 is a diagram illustrating a substrate (lens dyeing substrate) 1 to which a dye for dyeing is attached. For example, a lens dyeing substrate (hereinafter referred to as dyeing substrate) 1 is disposed in a vacuum and in non-contact with the lens, and the dye attached to the dyeing substrate 1 is heated by electromagnetic waves to sublimate the dye, It is used for dyeing by vapor deposition on the lens surface and heating under atmospheric pressure or under pressure.

<Base for dyeing>
With reference to FIG. 1, the dyeing | staining base | substrate 1 in a present Example is demonstrated. The upper side of FIG. 1 is a front view, and the lower side is a plan view. In addition, in the front view of FIG. 1, in order to show each layer in an easy-to-understand manner, the length in the thickness direction (vertical direction in the front view) of the dyeing substrate 1 is made longer than the actual length. In the dyeing substrate 1 illustrated in FIG. 1, the dye layer 4 is already formed by attaching the dye. For example, the dyeing substrate 1 mainly includes a substrate (base) 2 and a dye layer 4. Further, the dyeing substrate 1 may include an electromagnetic wave absorbing layer 6. In the dyeing substrate 1 illustrated in FIG. 1, the dyeing substrate 1 includes a substrate 2, a dye layer 4, and an electromagnetic wave absorption layer 6.

For example, the base 2 may be configured to use paper, a metal plate (for example, aluminum, iron, copper, etc.), glass, or the like. In the following description, the substrate 2 will be described using paper as an example. The base 2 serves as a base for holding other layers (such as the electromagnetic wave absorbing layer 6). In this embodiment, for example, the substrate 2 is a sheet-like substrate.

For example, the dyeing layer 4 is formed on the substrate 2 by a dye adhering portion 10 described later. For example, in this embodiment, the dye layer 4 uses at least red, blue, yellow, and three-color dyes. Of course, other colors may be used. These three color dyes are attached to the substrate 2 by an ink jet printer 11 described later. For example, the dye has at least sublimability. In addition, for example, it is preferable to use a dye having heat resistance that can withstand the heat during sublimation. As an example, in this embodiment, a quinophthalone-based sublimable dye or an anthraquinone-based sublimable dye is used (for example, see JP-A No. 2004-326018, JP-A No. 2003-185882, etc.). )

For example, the electromagnetic wave absorbing layer 6 is a layer formed at least on the side opposite to the surface to which the dye is adhered in the dyeing substrate 1 (upper side in the front view of FIG. 2). The electromagnetic wave absorption layer 6 has a higher electromagnetic wave absorption rate than the base 2. Specifically, the electromagnetic wave absorption layer 6 only needs to absorb at least an electromagnetic wave having a wavelength generated by the electromagnetic wave generation unit (see FIG. 6) 31 with a higher absorption rate than the base 2. As an example, in this example, electromagnetic wave absorption is achieved by a dry coating film of a colored ink containing a heat-resistant resin material (polyamideimide resin in this embodiment) and a black or dark pigment (black in this example). Layer 6 is formed. In this case, the electromagnetic wave absorbing layer 6 retains sufficient heat resistance, and the occurrence of wrinkles on the substrate 2 that is paper is suppressed. As a method for attaching (applying) the colored ink to the surface of the substrate 2, for example, a method using gravure printing, screen printing, spray, brush, roller, or the like can be employed. Of course, the electromagnetic wave absorbing layer 6 may not be formed of a heat resistant resin material but may be formed by a dry coating film of colored ink containing a black or dark pigment. The electromagnetic wave absorbing layer 6 can be formed using other materials and methods. In addition, the structure in which the electromagnetic wave absorption layer 6 is formed may be formed on either one side or both sides of the dyeing substrate 1. The region where the electromagnetic wave absorbing layer 6 is formed may be formed in a region that occupies a part of the dyeing substrate 1 or may be formed in all regions of the surface.

In addition, it is good also as a structure which provides a dye holding | maintenance layer in the base | substrate for dyeing | staining in a present Example. For example, the dye holding layer is formed on the surface to which the dye is attached. The region where the dye holding layer is formed may be a region including at least the region where the dye layer 4 is formed. Various materials can be used for the material of the dye holding layer. For example, a configuration in which a hydrophilic polymer material containing polyethylene oxide or polyethylene glycol is used as the material of the dye holding layer can be mentioned. Thus, by providing the dye holding layer, the dye is held in a stable state as compared with the case where the dye is directly attached to the surface of the substrate 2. In particular, when the substrate 2 is made of metal, if the dye is directly attached to the surface of the substrate 2, it is difficult to retain the dye due to bleeding or spreading of the dye, so it is better to provide a dye retaining layer.

<Preparation of substrate for dyeing>
FIG. 2 is a diagram for explaining the dye attaching portion 10 for attaching the dye to the base 2. The dye attaching part 10 produces the dyeing substrate 1 to which a dye (sublimation dye) for dyeing a lens is attached.

As an example, the dye adhering portion 10 of this embodiment adheres (prints in this embodiment) the dye to the dyeing substrate 1 using an ink jet printer 11. Accordingly, the dye attaching unit 10 can attach the dye having the color desired by the operator to the dyeing substrate 1 more accurately. That is, the accuracy of the amount of the dye to be attached to the dyeing substrate 1, the hue, the degree of gradation and the like is improved. In addition, the operator can easily handle the dye. Furthermore, by using the inkjet printer 11, the dye to be used is reduced.

In this embodiment, print data used for drive control of the ink jet printer 11 is created by a personal computer (hereinafter referred to as “PC”) 12. For example, the operator can easily adjust the hue, saturation, brightness, presence / absence and level of gradation of the dye attached to the dyeing substrate 1 by using, for example, draw software installed in the PC 12. The operator can repeatedly attach the dye to the plurality of dyeing substrates 1 with the same color by storing the print data in the memory of the PC 12, the memory of the inkjet printer 11, the USB memory, or the like. In addition, the operator can select one of a plurality of print data created in advance by a manufacturer or the like, and cause the inkjet printer 11 to execute printing.

Note that it is also possible to attach the dye to the dyeing substrate 1 without using the inkjet printer 11. For example, the dye attaching unit 10 may attach the dye to the dyeing substrate 1 by driving a roller, a dispenser, or the like, or printing using a screen or the like. Alternatively, the operator may attach the dye to the dyeing substrate 1 by using a brush or a roller without using the dye attaching portion 10.

When creating the dyeing substrate 1, for example, the creator of the dyeing substrate 1 (hereinafter referred to as the creator) sets the substrate 2 in the inkjet printer 11. The creator operates the PC 12 to perform printing with a preset hue and density. A dye layer 4 is printed in a circular shape on the surface of the printed substrate 2 as shown in FIG. For example, the number of dye layers on the substrate 2 can be arbitrarily set. In the present embodiment, a configuration in which two dye layers 4 are printed on the substrate 2 is taken as an example. Further, it is preferable that the diameter of the dye layer 4 to be printed is longer than the diameter of the lens that is actually dyed. This is because when the diameter of the dye layer 4 is shorter than the lens diameter, there is a possibility that the dye does not sufficiently spread over the entire colored side of the lens.

Further, the size of the substrate 2 used for the production of the dyeing substrate 1 is not particularly required, and a paper size usable for the inject printer 11 may be used. Further, the size of the base 2 may be used after output from the inject printer 11 with some extra blanks removed to fit a dyeing jig described later. In this embodiment, the shape of the dye layer 4 is circular. However, the shape is not limited to this, and may be any size and shape that allows the dye to reach the region desired to be dyed on the lens.

<Packaging of substrate for dyeing>
The prepared dyeing substrate 1 is packaged and sent as a lens dyeing substrate package (hereinafter referred to as a packaged product) 20 to each sales destination that performs dyeing. Hereinafter, the dyed substrate package in which the dyeing substrate 1 is packed will be described. FIG. 3 is a diagram for explaining an example of the configuration of the dyed substrate package 20. FIG. 4 is a diagram for explaining an example of a packing method for the dyeing substrate 1.

In this embodiment, for example, the package 20 is mainly composed of a lens dyeing substrate packing member (hereinafter referred to as a packing member) 21, a dyeing substrate 1, a shape maintaining member 25, a fixing member 26, and the like. For example, as the packing member 21, a bag, a container, etc. are mentioned. Of course, the packing member 21 may have any configuration that can pack the dyeing substrate 1. In the present embodiment, a case where a bag is used as the packing member 21 will be described as an example (details will be described later). In this embodiment, a case where a plurality of dyeing substrates 1 are packed will be described as an example. Further, in the package 20, a gas portion S is provided between the dyeing substrate 1 and the packaging member 21 (more specifically, the dye transfer suppression portion of the packaging member 21).

As shown in FIG. 4, for example, the dyeing substrate 1 is accommodated in a dyeing substrate packing member (hereinafter referred to as a packing member) 21 and gas is injected (the gas portion S is formed inside the packing member 21. In the state), the opening 21a of the packing member 21 is sealed by heat welding or the like, thereby being packed (sealed). For example, in the case of being accommodated in the packing member 21, a predetermined number (for example, 1, 2, 10, etc.) of the dyeing bases 1 are sandwiched between the two shape maintaining members 25 and fixed by the fixing member 26. It is accommodated in the packing member 21. As described above, the package 20 is formed by packing.

For example, in the present embodiment, when at least two or more dyeing substrates 1 are packed, a plurality of the dyeing substrates 1 are oriented in the same direction with the surface to which the dye for dyeing the lens is attached, It is packed. Thus, by directing the plurality of dyeing substrates 1 in the same direction, it is possible to suppress transfer of dyes between the dyeing substrates 1. As a result, it is possible to prevent the dyes from being mixed between the different dyeing substrates 1 to cause color unevenness or different colors during lens dyeing. In the present embodiment, the package 20 is configured such that the plurality of dyeing substrates 1 are packed in the same direction, but the present invention is not limited to this. For example, the plurality of dye bases 1 may be packaged in different directions. Further, for example, the plurality of dyeing substrates 1 may be configured such that a portion directed in the same direction and a portion directed in different directions are mixedly packed.

For example, in this embodiment, when at least two or more dyeing substrates 1 are packed, the dyes attached to each of the plurality of dyeing substrates 1 are packed so as to have the same color. . In this way, by mixing the dyeing bases 1 having the same color dyes with the plurality of dyeing bases 1 packed in the package 20, it is possible to prevent the dye colors from being mixed between the dyeing gases 1. can do. This suppresses the color of the lens when the lens is dyed from being different from the desired color. In the present embodiment, the dyeing substrate 1 having the same dye color is packed together, but the present invention is not limited to this. For example, the plurality of dyeing substrates 1 packed in the package 20 may be dyeing substrates 1 having different color dyes. Further, for example, the plurality of dyeing substrates 1 packed in the package 20 may be configured as the dyeing substrate 1 having a dye having a similar color.

The package 20 is configured as described above. In this way, the dyeing substrate 1 to which the lens dyeing dye is attached in advance is prepared, and the dyeing substrate 1 is packed in the packing member 21 and sent as a package 20 to the customer, so that it is dyed at the customer. There is no need to prepare the substrate 1 for use. As a result, it is possible to save labor and time for creating the dyeing substrate 1 at the sales destination. In addition, since the dyeing substrate 1 is prepared in advance by the vendor, it is possible to suppress variation in the amount of dyeing dye attached, and when the lens dyeing is performed using the dyeing substrate 1, it is desired. Can be dyed.

Hereinafter, each member forming the package 20 will be described.

<Lens dyeing substrate packaging member>
FIG. 5 is a diagram illustrating an example of the configuration of the packing member. For example, the packaging member 21 mainly includes a protection member 22, a change suppression unit 23, a transfer suppression unit 24, and the like.

For example, the protection member 22 is used to protect the contents of the change suppression unit 23, the migration suppression unit 24, and the packing member from scratches, dirt, chemicals, and the like.

For example, as the protective member 22, polyethylene terephthalate (PET), nylon film, or the like is used. Of course, the protection member 22 may be configured to protect the change suppression unit 23, the transfer suppression unit 24, the contents of the packing member, and the like. For example, the protective member 21 may have a layered structure, a patched structure, or the like. For example, when the protective member 21 is formed in a layer shape, the protective member 21 may be formed from one layer or may be formed from a plurality of layers. The protective member 21 may be formed of only a single material for protecting the packaging member 21 or may be a mixture of a material for protecting the packaging member 21 and another material. May be. In this embodiment, PET is used. In the present embodiment, the packaging member 21 includes the protection member 21, but the present invention is not limited to this. For example, the packaging member 21 may be configured such that the protective member 21 is not provided.

For example, the change suppressing unit 23 suppresses changes in the dye of the dyeing substrate 1 (for example, fading, dye moisture content change, dye viscosity change, etc.). For example, the change suppression unit 23 is configured by a member that blocks ultraviolet rays in order to suppress a change in the dye of the dyeing substrate 1. For example, the member that blocks ultraviolet rays includes a metal portion in order to suppress changes in the dye of the dyeing substrate 1. For example, examples of the metal part include aluminum, nickel, iron, copper, gold, silver, and stainless steel. The change suppression unit 23 preferably uses a member that blocks gas permeation in order to suppress a change in the dye of the dyeing substrate 1. Of course, the change suppressing unit 23 may be any member that can perform at least one of blocking ultraviolet rays and blocking gas permeation in order to suppress changes in the dye of the dyeing substrate 1. For example, the change suppression unit 23 may have a layered configuration, a patched configuration, or the like. For example, when the change suppressing unit 23 is formed in a layer shape, the change suppressing unit 23 may be formed of one layer or a plurality of layers. Note that the change suppressing unit 23 may be formed of only a single material for suppressing changes in the dye of the dyeing substrate 1, or a material for suppressing changes in the dye of the dyeing substrate 1. It may be a mixture with other materials.

In this embodiment, for example, the change suppressing unit 23 is made of aluminum. Aluminum is better because it is inexpensive and easy to process. Aluminum can also block ultraviolet rays and air. By using such a configuration, a change in the dye of the dyeing substrate 1 is suppressed. In the present embodiment, a metal is used as a member that suppresses a change in the dye of the dyeing substrate 1, but the present invention is not limited to this. For example, a member other than metal may be used as long as it is a member that can suppress a change in the dye of the dyeing substrate 1. For example, a filter that blocks ultraviolet rays, a polyimide sheet, or the like is used. In addition, when using a sheet | seat, as a sheet | seat, it is not limited to a polyimide sheet. For example, the sheet has at least one of heat resistance (for example, 250 ° C. or higher), low affinity with dyes, and no impurities that affect dyeing even when heated in vacuum. Any material having such properties may be used.

For example, the dye transfer suppression unit 24 suppresses the dye of the dyeing substrate 1 from being transferred inside the packing member 21. For example, the structure using the material containing polypropylene, polyethylene, etc. is mentioned. Of course, the dye transfer suppression part 24 should just be a member which can suppress dye transfer of the base | substrate 1 for dyeing | staining. For example, it is preferable that the dye transfer suppression unit 24 select a dye having a low affinity for the dye of the dyeing substrate 1. Further, for example, the dye transfer suppression unit 24 is preferably selected to have a high density in order to make it difficult for the dye particles to enter the dye transfer suppression unit 24 with respect to the dye of the dyeing substrate 1. In addition, for example, the dyeing suppression unit 24 may have a layered configuration, a patched configuration, or the like. For example, when the dye transfer suppression unit 24 is formed in a layer shape, it may be formed from one layer or a plurality of layers. In addition, the dye transfer suppression unit 24 may be formed of only a single material for suppressing dye transfer of the dyeing substrate 1 or to suppress dye transfer of the dyeing substrate 1. These materials and other materials may be mixed.

For example, in this embodiment, polypropylene is used as the dye transfer suppression unit 24. Polypropylene was determined to be more suitable as a material for suppressing dye transfer of the dyeing substrate 1 among materials compared in the experiments described later (details will be described later). See experimental example). In addition, the dye transfer suppression unit 24 may be formed of only a single material (for example, polypropylene) for suppressing dye transfer of the dyeing substrate 1 or the dye of the dyeing substrate 1. It may be a mixture of a material for suppressing the dye transfer and other materials.

For example, polypropylene includes unstretched polypropylene (Cast （Polypropylene) and biaxially stretched polypropylene (Oriented Polypropylene). In the present embodiment, unstretched polypropylene (hereinafter referred to as CPP) is used as the dye transfer suppression unit 24. CPP has a characteristic that it is strong and not easily damaged. For this reason, when the dyeing | staining base | substrate 1 is sent, possibility that the packing member 21 will be damaged becomes low.

As described above, by providing at least one of the change suppression unit 23 or the dye transfer suppression unit 24, the dyeing substrate 1 can be sent satisfactorily. As a result, the delivery destination (sales destination) of the package 20 can suppress color unevenness, discoloration, and the like during lens staining by performing lens staining using the dyeing substrate 1. That is, the sales destination can dye the lens in a desired color.

In the present embodiment, the packing member 21 is formed in the order of the protective member 22, the change suppression unit 23, and the dye transfer suppression unit 24 from the outside in contact with the outside. By forming the dye transfer suppression part 24 on the innermost side of the packaging member 21, it is possible to suppress the dye of the dyeing substrate 1 from being transferred to the inner side of the packing member 21. In the present embodiment, the packing member 21 is exemplified by a configuration in which the protective member 22, the change suppressing unit 23, and the dye transfer suppressing unit 24 are formed in this order from the outside in contact with the outside. Not. For example, the packing member 21 may have a configuration in which the order of the change suppression unit 23 and the transfer suppression unit 24 is exchanged. In this case, the packaging member 21 is formed in the order of the protection member 22, the dye transfer suppression unit 24, and the change suppression unit 23 from the outside in contact with the outside.

In addition, for example, the change suppressing unit 23 and the migration suppressing unit 24 may be formed in the entire region of the packing member 21 in the packing member 21. For example, the change suppression unit 23 and the migration suppression unit 24 may be formed in a partial region of the packing member 21. For example, when forming the change suppression part 23 and the dye transfer suppression part 24 in a partial region of the packing member, at least in the region of the packing member 21 in contact with the region where the dye is adhered in the dyeing substrate 1. The structure formed is mentioned. Of course, one of the change suppression unit 23 or the transfer suppression unit 24 may be formed in the entire region of the packaging member, and the other may be formed in a partial region of the packaging member.

In the present embodiment, the protection member 21, the change suppression unit 23, and the dye transfer suppression unit 24 are configured by separate members, but are not limited thereto. For example, the structure using the member which at least any one of the protection member 21, the change suppression part 23, and the dye transfer suppression part 24 may be used may be sufficient.

<Gas part>
For example, what is filled in the gas part S includes nitrogen, air, and the like. Thus, by providing the gas portion S between the dyeing substrate 1 and the packing member 21, when the dyeing substrate 1 is packed, when pressure is applied from the outside, it is used for dyeing. A space is easily formed between the base 1 and the packaging member 21. For this reason, the packing member 21 is less strongly pressed against the dyeing substrate 1, and the dye is hardly transferred to the packing member 21. Note that as the gas portion, it is better to use a gas having a small moisture content (for example, nitrogen, dried air, or the like). In this case, since the amount of water is small, it is possible to prevent the dye from being changed in color, being easily transferred by the dye being absorbed into the dye, and the like.

The gas portion S is not limited to the configuration provided between the dyeing substrate 1 and the packing member 21. For example, the gas part S may be provided between the dyeing substrate and the dyeing substrate. Further, for example, the gas part S may be provided between the dyeing substrate 1 and the shape maintaining member 25.

In addition, in the present Example, it was set as the structure by which the gas part S is provided in the package 20, However, It is not limited to this. The structure in which the gas part S is not provided in the package 20 may be sufficient.

<Shape maintenance member and fixing member>
For example, the shape maintaining member 25 is used to maintain the shape of the dyeing substrate 1. For example, in a substrate (particularly, a metal plate or paper) 2 to which a dye is adhered, the moisture content of the dye affects the surface on which the dye is adhered, and the substrate 2 may shrink when dried. However, the base 2 does not shrink on the surface where no dye is attached. As a result, a force in a shrinking direction is applied to only one surface, and the base 2 may be rounded.

For example, as the shape maintaining member 25, a member having a rigidity of the shape maintaining member 25 higher than that of the dyeing substrate is used so that the shape maintaining of the dyeing substrate 1 can be easily supported. For example, examples of the shape maintaining member 25 include members such as a slip sheet, a template, and a bar. Of course, the shape maintaining member 25 may be configured to support the maintenance of the shape of the dyeing substrate 1, and may be configured to use a member whose shape maintaining member 25 is less rigid than the dyeing substrate 1. Thus, by arranging the shape maintaining member 25, a change in the shape of the dyeing substrate 1 is suppressed.

For example, the fixing member 26 is used for fixing the dyeing substrate 1 and the shape maintaining member 25. For example, as the fixing member 26, a craft tape, a fastener or the like is used.

In this embodiment, the two shape maintaining members 25 are used. However, the present invention is not limited to this. The number of the shape maintaining members 25 that can support the maintenance of the shape of the dyeing substrate 1 (for example, 1, 2, 3, etc.) may be used.

In the present embodiment, the shape maintaining member 25 is arranged so as to sandwich the dyeing substrate 1, but is not limited thereto. For example, when packing a plurality of dyeing substrates 1, the dyeing substrate 1 and the dyeing substrate 1 may be arranged. Further, for example, the dyeing substrate 1 may be sandwiched and disposed between the dyeing substrates 1.

In the present embodiment, the shape maintaining member 25 is arranged on both surfaces of the dyeing substrate 1, but the present invention is not limited to this. For example, the shape maintaining member 1 may be arranged only on one surface of the dyeing substrate 1.
For example, when one shape maintaining member is used, it may be configured to be disposed only on one surface of the dyeing substrate 1. For example, the dyeing substrate 1 may be sandwiched between the dyeing substrates 1. It is good also as a structure arrange | positioned.

In addition, as the shape maintaining member 25, it is better to use a member to which dye is difficult to transfer for the shape maintaining member 25. By using a member that is difficult for dye to transfer to the shape maintaining member 25, it is possible to prevent the dye of the dyeing substrate 1 from transferring to the packing member 21.

In this embodiment, the shape maintaining member 25 is used. However, the shape maintaining member 25 may not be used. In this embodiment, the fixing member 26 is used. However, the fixing member 26 may not be used. Of course, a configuration in which at least one of the shape maintaining member 25 or the fixing member 26 is used may be employed.

It should be noted that a desiccant may be provided on the package 20. For example, silica gel, aluminum oxide, phosphorus pentoxide, calcium chloride, anhydrous magnesium sulfate, etc. can be used as the desiccant. By providing the desiccant, the dyeing substrate 1 can be dried, and the dyeing substrate 1 can be prevented from containing much water. Thereby, when the dyeing | staining base | substrate 1 contains the water | moisture content, it can suppress that the fall of the atmospheric | air pressure inside the vapor deposition part 30 (refer FIG. 6) worsens, and stable dyeing | staining can be performed.

The package 20 created as described above is sent to a lens dyeing destination (sales destination) for dyeing lenses. The seller opens the package 20 that has been sent and takes out the dyeing substrate 1. The sales destination performs lens dyeing using the dyeing substrate 1 taken out from the packing member 21. Hereinafter, a lens staining method will be described.

<Dyeing system>
FIG. 6 is a schematic diagram of a staining system showing a staining apparatus to be used. In the following, a case where a plastic lens 8 which is one of the resin bodies is dyed by a gas phase transfer dyeing method to produce a dyed plastic lens will be described.

According to this example, for example, polycarbonate resin (for example, diethylene glycol bisallyl carbonate polymer (CR-39)), polyurethane resin, allyl resin (for example, allyl diglycol carbonate and its copolymer, diallyl) Phthalates and copolymers thereof), fumaric acid resins (for example, benzyl fumarate copolymers), styrene resins, polymethyl acrylate resins, fiber resins (for example, cellulose propionate), thiourethane or thioepoxy It is also possible to dye the plastic lens 8 made of a highly refractive material such as the above.

The dyeing system 100 using the dyeing substrate (hereinafter referred to as substrate) 1 in this embodiment will be described. With reference to FIG. 6, a schematic configuration of the staining system 100 in the present embodiment will be described. The dyeing system 100 of the present embodiment includes a vapor deposition unit 30 and a dye fixing unit 50.

The vapor deposition section 30 sublimates the dye toward the plastic lens 8 by heating the dye attached to the dyeing substrate 1 with electromagnetic waves. As a result, the dye is deposited on the plastic lens 8. The plastic lens 8 may be formed with various layers such as a receiving film for facilitating the fixing of the dye in the fixing process described later. The vapor deposition unit 30 of this embodiment includes an electromagnetic wave generation unit 31, a vapor deposition jig 32, a pump 36, and a valve 37.

The electromagnetic wave generator 31 generates an electromagnetic wave that is absorbed by the electromagnetic wave absorbing layer 6 of the dyeing substrate 1. As an example, in the present embodiment, a halogen lamp that generates infrared rays is used as the electromagnetic wave generator 31. However, the electromagnetic wave generating unit 31 may be any unit that generates an electromagnetic wave that is easily absorbed by the electromagnetic wave absorbing layer 4 described later. Therefore, instead of the halogen lamp, a configuration that generates electromagnetic waves of other wavelengths such as ultraviolet rays and microwaves may be used. The vapor deposition unit 30 can raise the temperature of the dye in a short time by irradiating the dyeing substrate 1 with electromagnetic waves.

In addition, when the dye of the dyeing substrate 1 is sublimated, it may be possible to heat the dye by bringing a heated iron plate or the like into contact with the dyeing substrate 1. However, it is difficult to bring the dyeing substrate 1 and the iron plate or the like into contact uniformly (for example, without a gap). If the contact state is not uniform, the dye may not be heated uniformly and color unevenness may occur. On the other hand, the vapor deposition part 30 of a present Example can heat a dye uniformly with the electromagnetic waves from the electromagnetic wave generation part 31 spaced apart from the base | substrate 1 for dyeing | staining.

The deposition jig 32 holds the dyeing substrate 1 and the plastic lens 8. The evaporation jig 32 of this embodiment includes a lens support portion 33 and a base support portion 34. The lens support portion 33 includes a cylindrical base portion and a mounting table disposed inside the base portion. The plastic lens 8 is supported by the mounting table of the lens support 33 while being surrounded by the base. The substrate support part 34 is located at the upper end of the cylindrical base and supports the dyeing substrate 1 above the plastic lens 8. Although not shown in detail, when the outer peripheral edge portion of the dyeing substrate 1 is placed on the substrate support portion 34, the annular substrate pressing member is placed on the outer peripheral edge portion of the dyeing substrate 1. As a result, the position of the dyeing substrate 1 is fixed. In this embodiment, the substrate support 34 is more reliably held by placing a plate-like glass on the upper surface of the dyeing substrate 1 held by the substrate support 34. Glass transmits most of the infrared light.

The dyeing substrate 1 is arranged so that the surface on which the dye is attached faces the plastic lens 8. In this embodiment, since the dyeing substrate 1 is supported above the plastic lens 8, the dyeing substrate 1 is placed on the substrate support portion 34 so that the dye adhesion surface faces downward. Note that if the distance between the dye adhering surface of the dyeing substrate 1 and the plastic lens 8 is too small, the dye is not sufficiently dispersed and color unevenness tends to occur. In addition, if the distance between the dye adhering surface of the dyeing substrate 1 and the plastic lens 8 is too large, the dispersed dye may be terminated again, resulting in color unevenness, and the concentration of the deposited dye is also reduced. Therefore, it is desirable that the distance between the dyeing substrate 1 and the plastic lens 8 be an appropriate distance (for example, 5 mm to 30 mm).

The pump 36 discharges the gas inside the vapor deposition unit 30 to the outside, and lowers the atmospheric pressure inside the vapor deposition unit 30. The atmospheric pressure inside the vapor deposition section 30 at the time of vapor deposition may be, for example, about 133 Pa to 6.66 KPa. The valve 37 switches between opening and closing of the internal space of the vapor deposition unit 30.

The dye fixing unit 50 fixes the dye to the plastic lens 8 by heating the plastic lens 8 on which the dye is deposited. In this embodiment, an oven is used as the dye fixing unit 50. When an oven is used, the temperature of the plastic lens 8 gradually rises over a long period of time, so that a temperature difference is unlikely to occur. Therefore, the dye is easily fixed to the plastic lens 8 evenly.

It should be noted that the configuration of the dye fixing unit 50 can be changed. For example, the dye fixing unit 50 may heat the plastic lens 8 by causing the laser to scan on the plastic lens 8. In this case, the dye fixing unit 50 can intentionally generate a temperature difference according to the site of the plastic lens 8. For example, the dye fixing unit 50 may control the scanning of the laser according to the target gradation state when performing dyeing with gradation. The dye fixing unit 50 may control laser scanning according to the thickness of the plastic lens 8 or the like so that the temperature of each part of the plastic lens 8 becomes a desired temperature. Further, the dye fixing unit 50 may heat the plastic lens by directly irradiating the plastic lens 8 with electromagnetic waves.

Further, the processes performed in each of the vapor deposition unit 30 and the dye fixing unit 50 may be executed by one apparatus. For example, a staining apparatus that performs both the vapor deposition process performed by the vapor deposition unit 30 and the fixing process performed by the dye fixing unit 50 may be used. In this case, for example, the same heating means (for example, an infrared heater) may execute the heating of the dyeing substrate 1 in the vapor deposition process and the heating of the plastic lens 8 in the fixing process. The dyeing apparatus may automatically perform a plurality of steps (for example, from the vapor deposition step to the fixing step) in a series of flows.

As described above, the plastic lens 8 is dyed using the dyeing substrate 1. As described above, the sales destination (sales partner) receives the dyed substrate 1 sent thereto, and when the lens dyeing is performed, the lens can be dyed to a desired color by using the dyeing substrate 1. it can.

<Experimental example>
In this experimental example, at least red, blue, yellow, and three color dyes were used. Since the dye has sublimation properties and needs to withstand heat during sublimation, a quinophthalone sublimation dye or an anthraquinone sublimation dye was used. These three color dyes were adhered to the substrate by an ink jet printer to prepare a dyeing substrate. Note that paper was used as the substrate to which the dye was adhered.

The dyeing substrate thus prepared was vacuum-sealed in an aluminum pouch (a bag made of an aluminum material) in a state where a PE (polyethylene) film and a PP (polypropylene) film were superposed on each other. And it hold | maintained for 2 days in a 40 degreeC environment. After holding for 2 days, the degree of transfer to each film was confirmed visually. The confirmation results are shown in Table 1.

As shown in Table 1, when the film was held at 40 ° C. for 2 days, neither PE film nor PP film was transferred to the film. However, in the PE film, it was confirmed that the dye passed through the PE film (dye loss) and transferred to the aluminum pouch. Further, in the PP film, it was confirmed that the dye passed through the PE film (dye loss) and was slightly transferred to the aluminum pouch. That is, when the PP film and the PE film were compared, the dye was not transferred to both films, but the PE film was more dye-removed than the PP film. As a result, it can be said that the PP film is more likely to suppress dye transfer than the PE film.
