摘要：
There are provided a cosmetic sheet that obscures a discolored portion of the skin and a method for producing the cosmetic sheet. There are also provided an image-processing apparatus and an image-processing method for producing the sheet. The cosmetic sheet is put on a discolored portion of the skin. The cosmetic sheet includes a thin film, one surface of which is to be put on the skin, a complementary color layer placed on the other surface of the thin film and having a color tone complementary to the color of the discolored portion, a light scattering layer placed on the complementary color layer and containing a reflective material, and a coloring layer placed on the light scattering layer and containing a coloring material.
技术问题语段：
The patent text describes a method for applying a thin film with ink to cover up discolored regions on the human body, such as freckles or scars. The technique involves taking a picture of the skin to identify the discolored region, and then printing a color similar to the surrounding area on the thin film. This is then put on the skin to hide the discolored region. The technical problem being addressed is how to effectively cover up discolored regions on the body with a thin film and ink.
技术功效语段：
The patent text describes a problem with traditional cosmetic sheets. These sheets have a limitation where the color of a deeper layer cannot be seen through the skin-colored layer. To solve this problem, the patent proposes a new cosmetic sheet that includes a light scattering layer on top of a complementary color layer. This results in a more difficult visual recognition of the color of both the discolored region and the complementary color layer. This technical effect is important for creating a more realistic and effective cosmetic sheet.
权利要求：
1. A cosmetic sheet to be put on a discolored portion of skin, comprising: a thin film, one surface of which is to be put on the skin; a complementary color layer formed by applying an ink with a color tone complementary to the color of the discolored portion to the other surface of the thin film; a light scattering layer formed by applying an ink containing a reflective material to the complementary color layer and; a coloring layer placed formed by applying a coloring material ink to the light scattering layer, wherein each of the inks for the complementary color layer, the light scattering layer, and the coloring layer further contains a higher alcohol having three to five carbon atoms, purified water, and an acrylic resin, the acrylic resin contains at least one polymer selected from the group consisting of homopolymers of an acrylic monomer and copolymers of two or more acrylic monomers, and wherein the complementary color layer has a basic color of blue and has a maximum at a wavelength in the range of 380 to 570 nm in its spectral reflectance curve.
2. The cosmetic sheet according to Claim 1, wherein the light scattering layer has a thickness in the range of 0.1 to 10 when the complementary color layer has a thickness of 1.
3. The cosmetic sheet according to Claim 1, wherein the complementary color layer also has skin color.
4. The cosmetic sheet according to Claim 3, wherein the complementary color layer has a color tone of peach orange, purple, green, or pink.
5. The cosmetic sheet according to Claim 1, wherein the complementary color layer has different shades of color in a thickness direction.
6. A method for producing a cosmetic sheet to be put on a discolored portion of skin, the method comprising: a step of applying a complementary color layer ink containing a coloring material complementary to the color of the discolored portion to one surface of a thin film, the other surface of which is to be put on the skin, and drying the complementary color layer ink to form a complementary color layer; a step of applying a light scattering layer ink containing a reflective material to the complementary color layer and drying the light scattering layer ink to form a light scattering layer; and a step of applying a coloring layer ink containing a coloring material to the light scattering layer and drying the coloring layer ink to form a coloring layer, wherein each of the inks for the complementary color layer, the light scattering layer, and the coloring layer further contains a higher alcohol having three to five carbon atoms, purified water, and an acrylic resin, and the acrylic resin contains at least one polymer selected from the group consisting of homopolymers of an acrylic monomer and copolymers of two or more acrylic monomers.
7. The method for producing a cosmetic sheet according to Claim 7, wherein the light scattering layer has a thickness in the range of 0.1 to 10 when the complementary color layer has a thickness of 1.
