[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermochromic toy. More specifically, the present invention relates to a thermochromic toy exhibiting an iris pattern.

[0002]

2. Description of the Related Art Several proposals have been disclosed regarding thermochromic toys to which the taste and surprisingness of discoloration due to temperature change are imparted (Japanese Utility Model Application Laid-Open No. 60-71293).

[0003]

According to the present invention, the color change effect of the thermochromic toy as described above is more effectively exhibited, and the decorativeness, the variety of color change, the taste by the color change, and the unexpectedness are further enhanced. It is intended to provide a thermochromic toy.

[0004]

According to the present invention, a thermochromic layer 2 is formed on at least a part of the surface and the thermochromic layer 2 is formed.
A thermochromic toy 1 having a configuration in which a transparent iris thin film layer 3 is laminated on the toy 1 is required.

The structure of the present invention will be described with reference to the drawings. The thermochromic layer 2 is formed on a support 4 (transparent or opaque layer), and a transparent iris thin film layer 3 is laminated on the thermochromic layer 2. The structure laminated on the back surface, the support 4 itself forms the thermochromic layer 2 (a system in which a thermochromic material is impregnated and fixed on a support or a porous support formed by blending a thermochromic material, etc.) ) Can be exemplified as a basic mode.

In the above structure, a non-thermochromic layer may be appropriately provided below the thermochromic layer 2 so that the color change due to the color change of the thermochromic layer 2 can be more variously visualized.

The thermochromic layer 2 comprises a thermochromic material containing a conventionally known thermochromic dye, for example, a liquid crystal, an electron-donating color-forming organic compound, an electron-accepting compound, and a color-forming reaction between the two. Thermochromic material containing three components of an organic compound medium capable of reversibly generating a thermochromic material or a thermochromic material exhibiting thermochromic properties in the form of fine particles of a resin solid solution of the component (for example, Japanese Patent Publication No.
1-354414, JP-B-51-44706, JP-B-1-29398 and the like. The color changes before and after a predetermined temperature (color change point), and only one specific state can exist in a normal temperature range between the two states before and after the change. That is, the other state is maintained while the heat or cold required for the state to appear is applied, but returns to the state exhibited in the normal temperature range when the heat or cold is no longer applied (so-called state). This is a type in which a small hysteresis width for temperature-color density due to a temperature change is displayed and the color is changed.

[0008] Further, Japanese Patent Application Laid-Open No.
No. 264,285 describes a thermochromic material containing a color-memorizing thermochromic dye exhibiting a large hysteresis characteristic and discoloring (that is, the shape of a curve plotting a change in coloring density due to a temperature change indicates a temperature. A type in which the color changes following a significantly different path between a case where the temperature is increased from a temperature lower than the color changing temperature range and a case where the temperature is lowered from a temperature higher than the color changing temperature range: a low-temperature color changing point and a high-temperature color changing point In the normal temperature range between the above, the color changed at a temperature lower than the low-temperature side discoloration point or higher than the high-temperature side discoloration point can be stored and stored).

The thermochromic dye or the color-memorizing thermochromic dye described above is usually encapsulated in a microcapsule, dispersed in a medium containing a binder, applied as a color material such as ink or paint, and supported. A desired thermochromic layer 2 is formed on the body surface. Further, the microcapsules may be dispersed in a thermoplastic or thermosetting resin.

As the transparent iris thin film layer 3, a conventionally known structure is effective. Specifically, a transparent thin film layer composed of a transparent thin film layer and an uneven transparent thin film layer (the transparent thin film layer is made of titanium oxide, silicon oxide, zinc oxide, antimony oxide, zinc sulfide, magnesium fluoride, fluoride fluoride). Metal compound thin film layers exemplified by calcium, etc., copolymers of vinylidene chloride with vinyl chloride, vinyl acetate, vinyl alcohol, etc. or polyvinyl chloride, polyvinylidene chloride, polystyrene with any of vinyl chloride, styrene and copolymer, etc. Thin film layer having fine bubbles due to gas generated by decomposition of various thermoplastic resins by light, heat, etc., vinyl-based copolymer, cellulose-based copolymer, urethane-based copolymer and curing Various curing agents, compositions having a curable functional group, a thin film layer composed of an organic-substituted silicon-based compound, and the above organic material and titanium oxide, aluminum oxide Arm,
A transparent thin film layer made of inorganic fine particles such as zirconium oxide has a difference in refractive index from the thin film layer of 0.05 or more and a visible light transmittance of about 10% or more. An uncolored or colored transparent thin film layer, which may have light scattering on the surface and inside of the film and has a visible light transmittance of 50% or more: JP-A-61-2
No. 27098], an optical interference pattern film provided with a vapor deposition layer comprising one or more of oxides, sulfides and fluorides on one or both surfaces (Japanese Patent Application Laid-Open No. 60-32645), two or more types A transparent multilayer film exhibiting an optical interference phenomenon in which at least 100 layers made of polymers having different refractive indices are provided in the intermediate layer (USA: THE MEARL CORPORATION)
Product name: MEARL IRIDESCENT FI
LM) and the like.

Although the thermochromic layer 2 can be directly provided on the back surface of the transparent iris thin film layer 3, the thermochromic layer 2 is practically used by being joined to the support 4 provided with the thermochromic layer 2. An iris transfer foil [for example, a transfer foil having a protective resin layer and an iris thin film layer provided directly or via a release layer on a sheet substrate (Japanese Patent Application Laid-Open No. 61-69499)] Can be used to transfer and join the transparent iris thin film layer 3. As the support 4, all objects such as woven fabric and other fiber materials, paper, plastic, glass, ceramics, wood, and metal are effective.

The configuration of the combination of the iris thin film layer 3 and the thermochromic layer 2 is not limited to a planar shape, but may be wavy, irregular, or partially formed. A configuration in which a transparent film or the like is interposed therebetween is effective.

[0013]

According to the present invention , the iris thin film layer 3 is formed on the thermochromic layer 2.
The color change of the thermochromic layer 2 is observed through the laminated iris thin film layer 3.
The color effect due to the transparent iris thin film layer 3 and the color change due to the temperature change of the thermochromic layer 2 are fused, and various iris color changes are visually recognized. Depending on the color of the underlayer of the transparent iris thin film layer 3 (the color of the thermochromic layer 2 and the color of the non-color-changing layer seen in the bleached state of the thermochromic layer 2), the appearance that is viewed varies in various ways. That is, when the base is black, the transmitted light is absorbed and the interference light is emphasized, so that the gloss is enhanced. On the other hand, when the base is white, the interference light disappears due to the reflected light from the white surface. If the base is colored,
The interference light and the background color interact with each other, so that a clearer color can be seen, and a color that has variously changed depending on the viewing angle can be seen. The above-mentioned characteristics are combined with the color change of the thermochromic layer 2 to influence each other and make various changes in appearance visible.
