Description

  The present invention relates to a method for supplying color powder for nail using electrophotography, a color coating agent for nail and a method for producing the same, a nail chip, and an electrophotographic apparatus.

  In recent years, as a part of fashion, nail art for decorating the nails of hands and toes has attracted attention especially among women. Examples of the method of decorating the nails of hands and toes include a method of directly applying a color or pattern to the nails using a coating agent such as nail polish, a method of directly applying a decorated nail chip to the nails, etc. It is done.

  Above all, so-called gel nails that decorate by applying a gel-like coating agent to nails and curing the coating agent with light such as ultraviolet rays are rapidly spreading. The number of people who enjoy is increasing rapidly. Gel nails can be easily expressed in a variety of ways because the coating agent does not cure until irradiated with light such as ultraviolet rays, and the time from irradiation to curing of the coating agent is short. Therefore, such gel nail coating agents are required to have a wide variety of colors in accordance with fashion and fashion.

However, gel nail coating agents are still more expensive than nail polish and the like, and there is a problem that it takes a great deal of cost to arrange individual multicolor coating agents. Moreover, since the amount of the coating agent used by individuals is very small, there is also a problem that the whole amount cannot be used up.
In order to solve this problem, it is possible to obtain a desired color coating agent by mixing different color coating agents. However, in this method, the coating agents to be mixed belong to the same manufacturer. In addition, there is a problem that reproducibility is poor when trying to obtain a coating agent of the same color again. In addition, it is also possible to obtain a coating agent of a desired color by adding a colorant such as one or more kinds of pigments to a transparent or white coating agent, but there is no limitation on the type of manufacturer even in this method. However, it is not a sufficient solution in terms of reproducibility.

  In view of the above, there is a demand for a system capable of obtaining a small amount of various types of nail coating agents. For example, Patent Document 1 proposes an apparatus capable of supplying a coating material of a desired color in a custom-made manner. However, even in this apparatus, the amount to be supplied is not very small, and it is not possible to supply a wide variety of coating agents in a small amount.

[How to supply nail color powder]
The nail color powder supply method of the present invention uses an electrophotographic method to form an unfixed color toner image on a support with each color toner based on selected color information data. In this method, the toner that forms the color toner image is supplied as a toned nail color powder by discharging the toner image in an unfixed state to the support.

Specifically, the method for supplying the nail color powder of the present invention includes, for example, the following steps (1) to (6).

(4) The electrostatic latent image formed on the electrostatic latent image carrier is converted into each color toner. (5) Transfer process for transferring the color toner image formed on the electrostatic latent image carrier onto the support (6) Color transferred onto the support Discharging process for discharging the toner image in an unfixed state on the support

(1) Color information data acquisition step In the color information data acquisition step, the selected color information data is obtained, but the method for obtaining the selected color information data is not particularly limited. A user can arbitrarily select from a color chart in which color values in a color reproduction range, for example, CIE-XYZ color system or CIE-L ^* a ^* b ^* color system are set in advance. A method for obtaining color values based on the selected color sample as color information data, a method for obtaining a color image based on the read color image as color information data by reading a color image made of a desired color original with a scanner, etc., computer software For example, a method of obtaining color information data by inputting a desired color using the above-described method.

In the color information data acquisition step, when obtaining color information data selected using computer software or the like, a color value of a color required from a desired design pattern is calculated on the computer software, and this color value is calculated. It is preferable to use software capable of inputting the color information data based on, for example, an electrophotographic apparatus. Specifically, as shown in FIG. 1, if the design pattern of each finger is selected (see FIG. 1 (a)) and the design pattern of each finger is not the same, (See FIG. 1 (a-1)), and then select a desired color and figure from a plurality of color swatches and figure swatches, or create a unique pattern or pattern (FIG. 1 (b) )) And a design pattern is created (see FIG. 1C). Then, the color value of the color required from the design pattern is calculated on the computer software, and color information data based on the color value is input to an electrophotographic apparatus, for example, together with the fixed image of the design pattern as a color sample. A color powder for nail is output (see FIGS. 1D and 1D-1).

It is preferable to instruct the electrophotographic system in advance, for example, before or after (1) the color information data acquisition step, as information on the supply amount thus selected. An electrostatic latent image is formed in the (3) electrostatic latent image forming step in accordance with the supply amount data and the blending data obtained in the (2) blending data acquisition step based on the color information data.

A polyethylene terephthalate resin (PET) sheet is preferable from the viewpoint of the separation of the nail color powder from the support and the permeability of the coating agent described later to the support.

(6) Discharging Step In the discharging step, the color toner image transferred onto the support is not fixed on the support, and the color toner image is discharged from the electrophotographic system as it is. The discharging step is not particularly limited as long as the color toner image transferred onto the support can be discharged out of the electrophotographic system, that is, the electrophotographic apparatus without being melted or deformed by heat or pressure. It is preferable that the surface of the color toner image is not in contact with the peripheral members of the electrophotographic system and can be discharged out of the electrophotographic system.
