[0027] DESCRIPTION OF EMBODIMENT METHODS

[0028] Embodiments of this disclosure will be described below with reference to the drawings. [Fig. 1] is a diagram illustrating an example of an assembly 1 of fusible set beads 2 (2A, 2B, and 2C). The fusible set beads 2 are made of a water-soluble resinous material. In particular, the fusible set beads 2 are formed by mixing polyvinyl alcohol with a resin and kneading the mixture. The resin for forming the fusible set beads 2 can be freely chosen from a transparent, translucent, or opaque material. The translucency of the fusible set beads 2 can be controlled by the dye content of the bead. Specific examples will be described below. The shape of the Fuse beads for game 2 can be of various shapes, such as a sphere, a convex polyhedron, or a concave polyhedron (also called a convex-concave polyhedron), as illustrated in [Fig. 1]. A concave polyhedron is a polyhedron where the dihedral angle of any edge exceeds 180 degrees, and is a polyhedron other than a convex polyhedron.

[0029] The fusible bead 2A of [Fig. 1] is spherical. The fusible bead 2B, of convex polyhedral type, is a rhombic triacontahedron. The fusible bead 2C, of ​​concave polyhedral type, is a star polyhedron.

[0030] The fusible bead of game 2 is formed by mixing polyvinyl alcohol (PVA), glycerin, calcium stearate and a dye, and then performing injection molding using a mold having a predetermined shape.

[0031] Figures 2 and 3 are composition tables of examples 1 to 18 of fusible beads for set 2. [Fig. 4] is a composition table of comparative examples 1 to 12 of fusible beads for set 2. In Figures 2 to 4, the content of each component is indicated in [g], and the numbers in parentheses indicate the proportion of the dye when the total amount of polyvinyl alcohol (PVA), glycerin and calcium stearate is fixed at 100 parts by mass.

[0032] Examples 1 to 3 are colored yellow using phthalocyanine green (pigment), a yellow fluorescent dye, and ethylene bis(stearamide) in a mass ratio of 6:400:59. Examples 4 to 6 are colored green using phthalocyanine green (pigment) and a yellow fluorescent dye in a mass ratio of 3:2. Examples 7 to 9 are colored purple using brilliant blue FCF (blue no. 1) and acid red 52 (red no. 106) in a mass ratio of 5:2. Examples 10 to 12 are colored blue using brilliant blue FCF (blue no. 1).

[0033] Examples 13 and 14 are colored red using phloxine B (red no. 104) as the colorant. Examples 15 to 17 are colored pink using acid red 52 (red no. 106) as the colorant. The colorants used in examples 7 to 18 are all food colorings.

[0034] In each example, examples of the same color formed according to different shapes of a convex polyhedron, a concave polyhedron, and a sphere are shown. The fusible beads in set 2 of examples 1, 4, 7, 10, 13, and 16 are convex polyhedra and, in the present embodiment, are all rhombic triacontahedra. The fusible beads in set 2 of examples 2, 5, 8, 11, 14, and 17 are concave polyhedra and, in the present embodiment, are all star polyhedra.

[0035] The fusible beads of set 2 of examples 1 to 18 all contain polyvinyl alcohol (PVA), glycerin, calcium stearate and a dye, and are translucent.

[0036] In [Fig. 4], comparative examples 1 and 2 are colored yellow using tartrazine (yellow no. 4) and sunset yellow FCF (yellow no. 5) as colorants in a mass ratio of 120:1. Comparative examples 3 and 4 are colored green using brilliant blue FCF (blue no. 1) and tartrazine (yellow no. 4) as colorants in a mass ratio of 5:2.8. Comparative examples 5 and 6 are colored violet using erythrosine (red no. 3) and indigo carmine (blue no. 2) as colorants in a mass ratio of 5:8.

[0037] Comparative examples 7 and 8 are colored blue using erythrosine (red no. 3), brilliant blue FCF (blue no. 1), and tartrazine (yellow no. 4) as colorants in a mass ratio of 15:425:2. Comparative examples 9 and 10 are colored red using erythrosine (red no. 3) and sunset yellow FCF (yellow no. 5) as colorants in a mass ratio of 60:1. Comparative examples 11 and 12 are colored pink using erythrosine (red no. 3), indigo carmine (blue no. 2), and tartrazine (yellow no. 4) as colorants in a mass ratio of 60:4:1.

[0038] In all cases, the fusible beads of set 2 of the present embodiment (examples 1, 2, 4, 5, 7, 8, 10, 11, 13, 14, 16 and 17) were visually brighter and had more vivid colours than comparative examples 1 to 12.

[0039] A quantitative evaluation method is then described. In the present embodiment, the produced fusible bead 2 was photographed and evaluated to determine the vividness of its appearance. Figure 5 is a diagram illustrating a method for evaluating the fusible bead 2. First, the fusible bead 2 was photographed by a camera 31. The camera 31 used for the evaluation was a Nikon D850 camera equipped with a Nikon PC-E Micro NIKKOR 85 mm lens. The camera 31 settings were ISO 400, shutter speed 1 / 100 s, aperture f / 5.6, and white balance (WB) 5000 K.

[0040] Illumination light L emitted by a light source 33 was shone onto the fuse bead 2, placed as the subject on a photographic support 32, from directions diagonally above the left and right sides, at an irradiation angle θ = 45 degrees. Illumination light L had a luminous flux of 2500 mW and a color temperature of 5000 K. Illumination light L was shone onto the fuse bead 2 as diffuse light that had passed through tracing paper 34.

[0041] Next, using a suitable computer, the image data (in RGB format) of the fuse bead of game 2, acquired by the photographic device 31, were converted into data (HSV data) including the hue (H), saturation (S) and value (V) corresponding to each pixel, and a tabulation process was carried out.

[0042] Figures 6 to 11 are graphs illustrating the saturation and value distributions for the fusible beads of set 2 of examples 1 to 18. The evaluation results of the fusible beads of set 2 in the shape of convex polyhedrons and concave polyhedrons of each color are compared with the evaluation results of the fusible beads of set 2 formed using the components of the comparative examples.

[0043] In Figures 6 to 11, compared to fusible beads of set 2 of the same color and shape, in all cases, fusible beads of set 2 of the present embodiment (examples 1, 2, 4, 5, 7, 8, 10, 11, 13, 14, 16 and 17) have a higher value than comparative examples 1 to 12. Moreover, when the examples are compared to the comparative examples, the relationship between the value and the saturation tended to differ depending on the color.

[0044] For example, fusible beads in set 2, exhibiting yellow, green, and purple colors, had a value of 70% or more and a saturation of 60% or less when formed according to a convex or concave polyhedron (Examples 1, 2, 4, 5, 7, and 8). Compared to the comparative examples, the saturation was approximately 40% lower (Examples 1 and 2) or the value was approximately 20% higher (Examples 4, 5, 7, and 8).

[0045] The yellow or green fusible beads of set 2 had a wavelength band (peak at approximately 555 nm) where the luminous efficiency function of human photopic vision was high, and consequently, the color appeared vivid even when the saturation was low. Furthermore, shaping the fusible beads of set 2 to give them a high value and making them transparent resulted in a bright, sparkling appearance. The purple fusible beads of set 2 had the same saturation as the comparative examples, but their overall value was higher, giving them a vivid appearance.

[0046] The blue, red, and pink fusible beads of set 2 had a value of 75% or more and a saturation range between a lower and upper limit of 75% or more when formed according to a convex or concave polyhedron (Examples 10, 11, 13, 14, 16, and 17). Compared to the comparative examples, the saturation of the examples was about the same (Examples 10, 11, 13, and 14) or about 40% higher (Examples 16 and 17), and the value of the examples was about 10% to 20% higher (Examples 10, 11, 13, 14, 16, and 17).

[0047] The blue fusible bead of set 2 had a value of 75% or more and a saturation range between a lower limit and an upper limit of 95% or Furthermore, in the present embodiment, the saturation was widely distributed in the range between 0% and 100%. Therefore, since the blue fusible bead 2 had a high value and a wide saturation range between a lower and upper limit, when formed according to a convex or concave polyhedron, the blue fusible bead 2 receives reflected or transmitted light from external surfaces at multiple angles, allowing various saturation regions to be observed and thus producing an overall sparkling and vivid appearance.

[0048] The red fusible bead 2 had a value of 80% or more and a saturation range between a lower and an upper limit of 75% or more. In the present embodiment, the saturation was broadly distributed in the range between 0% and approximately 75%. Since the red fusible bead 2 had a high value and a wide saturation range between a lower and an upper limit, when formed according to a convex or concave polyhedron, the red fusible bead 2 receives reflected or transmitted light from external surfaces at multiple angles, allowing various saturation regions to be observed and thus producing an overall sparkling and vivid appearance.Furthermore, for the red fuse bead in set 2, increasing the value allows for a bright and vivid appearance, even though the luminous efficiency function is lower than that of the blue bead (examples 10 and 11).

[0049] The pink fusible bead 2 had a value of 80% or more and a saturation range between a lower and upper limit of 85% or more. In the present embodiment, the saturation was broadly distributed in the range from 0% to approximately 90% to 100%. Since the pink fusible bead 2 had a high value and a wide saturation range between a lower and upper limit, when formed according to a convex or concave polyhedron, the pink fusible bead 2 receives reflected or transmitted light from external surfaces at multiple angles, allowing various saturation regions to be observed and thus producing an overall sparkling and vivid appearance.

[0050] In one embodiment of the fusible bead set 2, the dye represents 0.01 parts by mass or less per 100 parts by mass of the total polyvinyl alcohol, glycerin, and calcium stearate, except for the red fusible bead set 2. In contrast, the comparative example contains more than 0.01 parts by mass of the dye.

[0051] The embodiment of the present disclosure described above makes it possible to propose a fusible game bead according to the following aspects.

[0052] The fusible game bead according to a first aspect contains polyvinyl alcohol, glycerin, calcium stearate and a dye, is translucent and, when it is formed according to a convex polyhedron or a concave polyhedron, has a value of 70% or more and a saturation of 60% or less.

[0053] According to this aspect, it is effective to set the value to a high level and the saturation to a low level to make the color more vivid, especially when the color has a high luminous efficacy function. When the game fuse bead is translucent and set to have a high value, a decrease in value due to subtractive color mixing is reduced, resulting in a bright, well-colored, vivid-looking, and highly playable game fuse bead.

[0054] The fusible game bead according to a second aspect contains polyvinyl alcohol, glycerin, calcium stearate and a dye, is translucent and, when formed according to a convex polyhedron or a concave polyhedron, has an observed value of 75% or more and a saturation range between a lower limit and an upper limit of 75% or more.

[0055] According to this aspect, it is effective to set the value and saturation to a high level to make the color more vivid, especially when a color with a low luminous efficacy is chosen for the colorant. The fusible gaming bead is translucent and designed to have a high value and high saturation; a decrease in value due to subtractive color mixing is reduced, resulting in a bright, well-colored, vivid-looking, and highly playable fusible gaming bead.

[0056] The fusible play bead according to a third aspect has a value of 75% or more and a saturation range between a lower limit and an upper limit of 95% or more.

[0057] According to this aspect, since the fusible bead of game 2 has a high value and an extremely wide saturation range between a lower limit and an upper limit, when formed according to a convex polyhedron or a concave polyhedron, the fusible bead of game 2 receives reflected light or transmitted light from external surfaces at multiple angles, which makes it possible to observe various saturation regions and thus produces an overall sparkling and vivid appearance.

[0058] The fusible play bead according to a fourth aspect has a value of 80% or more and a saturation range between a lower limit and an upper limit of 75% or more.

[0059] According to this aspect, given that the fusible bead of set 2 has a higher value and a wide saturation range between a lower and an upper limit, when formed according to a convex polyhedron or a concave polyhedron, the fusible bead of set 2 receives reflected light or transmitted light from surfaces exterior shots from multiple angles allow observation of various saturation regions, thus producing an overall sparkling and vivid appearance.

[0060] The fusible bead of the game according to a fifth aspect has a saturation range between a lower limit and an upper limit of 85% or more.

[0061] According to this aspect, since the fusible bead of game 2 has an extremely wide saturation range between a lower limit and an upper limit, when formed according to a convex polyhedron or a concave polyhedron, the fusible bead of game 2 receives reflected light or transmitted light from external surfaces at multiple angles, which makes it possible to observe various saturation regions and thus produces an overall sparkling and vivid appearance.

[0062] The colorant in the game fuse bead according to a sixth aspect is a food coloring.

[0063] According to this aspect, an extremely safe fusible bead of set 2 can be formed.

[0064] The fusible bead of the game according to a seventh aspect is formed according to a convex polyhedron or a concave polyhedron.

[0065] According to this aspect, the fuse bead of the game 2 receives light reflected or transmitted from external surfaces at multiple angles, which allows various saturation regions to be observed and thus produces an overall sparkling and vivid appearance.

[0066] The method of implementation of this disclosure has been described above. Aspects of this disclosure are not limited to this method of implementation.
