[0010] Embodiments of this disclosure will be described below with reference to the drawings. Figure 1 shows an example of an assembly 1 of weldable bead toys 2 (2A, 2B, 2C). The weldable bead toys 2 are formed from a water-soluble resin. Specifically, the weldable bead toys 2 are formed by mixing polyvinyl alcohol with the resin. The resin forming the weldable bead toys 2 can be any material, such as a transparent material, a translucent material, or an opaque material. The translucency of the weldable bead toys 2 can be selected by the amount of colorant contained. Specific examples will be described later. The shape of the weldable bead toys 2 can be various forms, such as a sphere, a convex polyhedron, or a concave polyhedron (also called a concave-convex polyhedron), as illustrated in Figure 1. A concave polyhedron is a polyhedron in which the dihedral angle at any edge exceeds 180 degrees, and is a polyhedron other than a convex polyhedron.

[0011] The weldable bead toy 2A in Figure 1 is spherical. The convex polyhedron weldable bead toy 2B is a regular triacontahedron. The concave polyhedron weldable bead toy 2C is a stellated polyhedron.

[0012] The weldable bead toy 2 is formed by mixing polyvinyl alcohol (PVA), glycerin, calcium stearate, and a coloring agent, and then using injection molding or the like with a mold having a predetermined shape.

[0013] Figures 2 and 3 are component tables for Examples 1 to 18 of Weldable Bead Toy 2. Figure 4 is a component table for Comparative Examples 1 to 12 of Weldable Bead Toy 2. Figures 2 to 4 show the content of each component in units [g], and the percentage of colorants in parentheses is shown when polyvinyl alcohol (PVA), glycerin, and calcium stearate are each present in 100 parts by mass.

[0014] In Examples 1 to 3, phthalocyanine green (pigment), a yellow fluorescent dye, and ethylene bis stearamide are used in a mass ratio of 6:400:59 as colorants, and the resulting product is colored yellow. In Examples 4 to 6, phthalocyanine green (pigment) and a yellow fluorescent dye are used in a weight ratio of 3:2 as colorants, and the resulting product is colored green. In Examples 7 to 9, Food Blue No. 1 and Food Red No. 106 are used in a mass ratio of 5:2 as colorants, and the resulting product is colored purple. In Examples 10 to 12, Food Blue No. 1 is used as a colorant, and the resulting product is colored blue.

[0015] In Examples 13 to 14, Food Red No. 104 is used as a colorant, and the resulting product is colored red. In Examples 15 to 17, Food Red No. 106 is used as a colorant, and the resulting product is colored pink. All the colorants used in Examples 7 to 18 are food dyes.

[0016] Also, in each example, examples of forming different shapes of convex polyhedrons, concave polyhedrons, and spheres for the same color are shown. The welded bead toys 2 in Examples 1, 4, 7, 10, 13, and 16 are convex polyhedrons, and all are regular icosahedrons in this embodiment. The welded bead toys 2 in Examples 2, 5, 8, 11, 14, and 17 are concave polyhedrons, and all are star polyhedrons in this embodiment.

[0017] The welded bead toys 2 in Examples 1 to 18 all contain polyvinyl alcohol (PVA), glycerin, calcium stearate, and a colorant, and have translucency.

[0018] In FIG. 4, in Comparative Example 1 and Comparative Example 2, Food Yellow No. 4 and Food Yellow No. 5 are used in a mass ratio of 120:1 as colorants, and the resulting product is colored yellow. In Comparative Example 3 and Comparative Example 4, Food Blue No. 1 and Food Yellow No. 4 are used in a mass ratio of 5:2.8 as colorants, and the resulting product is colored green. In Comparative Example 5 and Comparative Example 6, Food Red No. 3 and Food Blue No. 2 are used in a mass ratio of 5:8 as colorants, and the resulting product is colored purple.

[0019] Comparative Examples 7 and 8 were colored blue when Red No. 3, Blue No. 1, and Yellow No. 4 were used as colorants in a mass ratio of 15:425:2. Comparative Examples 9 and 10 were colored red when Red No. 3 and Yellow No. 5 were used as colorants in a mass ratio of 60:1. Comparative Examples 11 and 12 were colored pink when Red No. 3, Blue No. 2, and Yellow No. 4 were used as colorants in a mass ratio of 60:4:1.

[0020] In all cases, the weldable bead toys 2 of this embodiment (Examples 1, 2, 4, 5, 7, 8, 10, 11, 13, 14, 16, 17) were visually brighter and produced more vivid colors than Comparative Examples 1 to 12.

[0021] Next, a quantitative evaluation method will be described. In this embodiment, the created weldable bead toy 2 was photographed and its visual vibrancy was evaluated. Figure 5 is an explanatory diagram of the evaluation method for the weldable bead toy 2. First, the weldable bead toy 2 is photographed by the photographic device 31. The photographic device 31 used for evaluation is a Nikon D850 camera and a Nikon PC-E Micro NIKKOR 85mm camera lens. The settings for the photographic device 31 are ISO 400, shutter speed 1 / 100s, f-number f / 5.6, and white balance (WB) 5000K.

[0022] The illumination light L emitted from the light source 33 is directed at the weldable bead toy 2, which is placed on the shooting table 32 as the subject, from the left, right, and above at an illumination angle θ=45 degrees. The illumination light L has a luminous flux of 2500 lm and a color temperature of 5000 K. The illumination light L is also directed at the weldable bead toy 2 as diffused light transmitted through the tracing paper 34.

[0023] Next, using an appropriate computer, the image data (RGB data format) of the weldable bead toy 2 acquired by the imaging device 31 was converted into data (HSV data) containing the values ​​of hue, saturation, and volume corresponding to each pixel, and then aggregated.

[0024] Figures 6 to 12 show the distribution of saturation and brightness for the weldable bead toys 2 of Examples 1 to 21. The evaluation results of the convex and concave polyhedra of the weldable bead toys 2 of each color are compared with those of the weldable bead toys 2 formed with the components of the comparative example.

[0025] As shown in Figures 6 to 11, when comparing weldable bead toys 2 of the same color and shape, the weldable bead toys 2 of this embodiment (Examples 1, 2, 4, 5, 7, 8, 10, 11, 13, 14, 16, 17) all have higher brightness than Comparative Examples 1 to 12. Furthermore, the relationship between brightness and saturation showed different trends depending on the color when comparing the examples and comparative examples.

[0026] For example, when the weldable bead toys 2 exhibiting yellow, green, and purple colors were formed into convex or concave polyhedra, the observed brightness was 70% or higher and the saturation was 60% or lower (Examples 1, 2, 4, 5, 7, 8). However, compared to the comparative examples, the saturation was about 40% lower (Examples 1, 2) or the brightness was about 20% higher (Examples 4, 5, 7, 8).

[0027] The yellow or green weldable bead toy 2 is made of beads in a wavelength range where human photopic luminosity is high (peaking at approximately 555 nm), so even with low saturation, the colors appear vibrant. Furthermore, because the weldable bead toy 2 is formed with high brightness and transparency, it has a bright and sparkling appearance. The purple weldable bead toy 2 has a similar saturation to the comparative example, but its overall higher brightness results in a more vivid appearance.

[0028] The weldable bead toys 2, exhibiting blue, red, and pink colors, showed a brightness of 75% or higher and a saturation range of 75% or higher when formed into convex or concave polyhedra (Examples 10, 11, 13, 14, 16, 17). However, compared to the comparative examples, the saturation was at a similar level (Examples 10, 11, 13, 14) or about 40% higher (Examples 16, 17), and the brightness was about 10% to 20% higher (Examples 10, 11, 13, 14, 16, 17).

[0029] The blue weldable bead toy 2 has a brightness of 75% or more and a saturation range of 95% or more. In this embodiment, the saturation is widely distributed in the range from 0% to 100%. Therefore, because the blue weldable bead toy 2 has high brightness and a wide saturation range, when formed into a convex or concave polyhedron, it receives reflected or transmitted light from multiple angles of the outer surface, allowing observation of various saturation ranges, and as a whole, it is formed vividly, creating a sparkling effect.

[0030] The red weldable bead toy 2 has a brightness of 80% or more and a saturation range of 75% or more. In this embodiment, the saturation is widely distributed in the range from 0% to approximately 75%. Because the red weldable bead toy 2 also has high brightness and a wide saturation range, when formed into a convex or concave polyhedron, it receives reflected or transmitted light from multiple angles of the outer surface, allowing observation of various saturation ranges, and as a whole, it is formed vividly, creating a sparkling effect. Furthermore, by increasing the brightness of the red weldable bead toy 2, it can be perceived as brighter and more vivid even with lower luminous efficiency compared to the blue (Examples 10, 11).

[0031] Furthermore, the pink weldable bead toy 2 has a brightness of 80% or more and a saturation range of 85% or more. In this embodiment, the saturation is widely distributed in the range from 0% to approximately 90-100%. Also, because the pink weldable bead toy 2 has high brightness and a wide saturation range, when formed into a convex or concave polyhedron, it receives reflected or transmitted light from multiple angles of the outer surface, allowing observation of various saturation ranges, and as a whole, it creates a sparkling effect and is vividly formed.

[0032] One embodiment of the weldable bead toy 2 contains 100 parts by mass of polyvinyl alcohol, glycerin, and calcium stearate, with the exception of the red weldable bead toy 2, the coloring agent being 0.01 parts by mass or less. In contrast, the comparative example contains 0.01 parts by mass or more of coloring agent.

[0033] According to the embodiments of this disclosure described above, a weldable bead toy in the following form can be provided.

[0034] The weldable bead toy according to the first embodiment contains polyvinyl alcohol, glycerin, calcium stearate, and a coloring agent, is translucent, and when formed into a convex polyhedron or a concave polyhedron, the observed brightness is 70% or more and the saturation is 60% or less.

[0035] According to this embodiment, by setting the brightness to a higher level and the saturation to a lower level, it is particularly effective in producing more vivid colors when selecting colors with high luminosity as colorants. Weldable bead toys can be constructed to be bright, vividly colored, and visually appealing, with a high level of brightness, by suppressing the decrease in brightness due to subtractive color mixing, thus providing a highly playable weldable bead toy.

[0036] The weldable bead toy according to the second embodiment contains polyvinyl alcohol, glycerin, calcium stearate, and a coloring agent, is translucent, and when formed into a convex polyhedron or a concave polyhedron, the observed brightness is 75% or more and the saturation range is 75% or more.

[0037] According to this embodiment, setting the brightness and saturation to a higher level is particularly effective in producing vivid colors when selecting colors with low luminous efficiency as colorants. Weldable bead toys can be constructed to be bright, vividly colored, and visually appealing, with high brightness and saturation levels, thereby suppressing the decrease in brightness due to subtractive color mixing.

[0038] The weldable bead toy according to the third embodiment has a brightness of 75% or more and a saturation range of 95% or more.

[0039] According to this embodiment, the weldable bead toy 2 has high brightness and a particularly wide range of saturation. Therefore, when formed into a convex or concave polyhedron, it receives reflected or transmitted light from multiple angles of the outer surface, allowing observation of various saturation ranges, and as a whole, it creates a sparkling effect and is vividly formed.

[0040] The weldable bead toy according to the fourth embodiment has a brightness of 80% or more and a saturation range of 75% or more.

[0041] According to this embodiment, the weldable bead toy 2 has higher brightness and a wider range of saturation. Therefore, when formed into a convex or concave polyhedron, it receives reflected or transmitted light from multiple angles of the outer surface, allowing observation of various saturation ranges, and as a whole, it creates a sparkling effect and is vividly formed.

[0042] The weldable bead toy according to the fifth embodiment has a saturation range of 85% or more.

[0043] According to this embodiment, since the weldable bead toy 2 has a particularly wide range of saturation, when formed into a convex or concave polyhedron, it receives reflected or transmitted light from multiple angles of the outer surface, allowing observation of various saturation ranges, and as a whole, it is formed vividly, creating a sparkling effect.

[0044] In the sixth embodiment of the weldable bead toy, the coloring agent is food coloring.

[0045] According to this embodiment, a highly safe weldable bead toy 2 can be formed.

[0046] The weldable bead toy according to the seventh embodiment is formed into a convex polyhedron or a concave polyhedron.

[0047] According to this embodiment, by receiving reflected or transmitted light from multiple angles of the outer surface, a range of saturation can be observed, and as a whole, a sparkling effect can be created, forming a vivid, weldable bead toy 2.

[0048] This concludes the description of the embodiments of the present disclosure, but the embodiments of the present disclosure are not limited to these embodiments. [Explanation of Symbols]
