[Problem that the invention attempts to solve]

As mentioned above, this type of thermochromic figurative toy is suitable for use in the room temperature range (approximately 10 to 35 degrees Celsius). The appearance that occurs in the temperature range) can be changed to a cooling method that is slightly lower than the room temperature range, or a cooling method that is slightly higher than the normal temperature range. The color is changed using a heating method that generates heat, and the appeal point is the unexpectedness and transformability of the color change. I'm on the go.

[0005] Regarding the thermochromic toy having the thermochromic properties described above, when the user purchases the toy, Or, when using the doll for play for the first time after purchasing it, , a sleeping doll with closed eyelids is transformed into a doll awakened from sleep with open eyelids. A toy with a product concept that resembles a doll with closed eyelids. Then, if the environmental temperature is low or high outside the above normal temperature range, an unwanted aspect (previous There is a concern that dolls with open eyelids may be seen in commemorative doll toys. The product concept In a doll toy with a thermochromic color, the thermochromic image contains a color-memory thermochromic pigment. For systems colored with wood, once the temperature is below the discoloration point on the low temperature side or above the discoloration point on the high temperature side. When exposed to a temperature range, at the time of purchase, the eyelids appear to be awake from sleep with the eyelids open. There is a possibility that

[0006] The present invention is a thermochromic toy that has a specific product concept as described above as a color change requirement. In this case, the user should at least be aware of the involuntary aspects at the time of purchase or after using the product for play. You can enjoy the appearance change due to thermal discoloration according to the setting without exposing it to the front, and adds another aspect that can be erased by water in addition to the change in aspect due to thermal discoloration of the thermochromic image. The aim is to improve the product's marketability.

[0007]

[Means to solve the problem]

The thermochromic figurative toy of the present invention will be explained with reference to the drawings. The thermochromic figurative toy 1 of the present invention is a thermochromic figurative toy 1 colored with a coloring material containing a thermochromic material. Color image 3 is a thermal change pattern that imitates figures such as dolls and animals formed on the plastic surface. In a colored figurative toy, the plastic surface of the toy is coated with a water-erasable non-discoloring dye. A configuration in which a color layer 4 is provided is required. Furthermore, the water erasable non-discoloration The colored layer 4 is characterized by being a fixed layer in which a pigment is dispersed in a water-soluble resin.

[0008] In the above, the thermochromic image 3 is a thermochromic image containing a conventionally known thermochromic dye. materials, such as liquid crystals, electron-donating color-forming organic compounds, color developers for the compounds, and A thermochromic material containing three components of compounds that serve as a medium for causing the color reaction of both of the above. or a thermochromic material (e.g. , JP 51-35414, JP 51-44706, JP 1- 29398, etc.). The above values are at a certain temperature (color change point). As a result, the color changes before and after the change, and only one of the states before and after the change occurs at room temperature. Only the state can exist. That is, the other state requires maintained while heat or cold is applied; If the temperature changes, the state returns to the state it exhibits at room temperature (so-called temperature-color density due to temperature change (It is a type that exhibits a small hysteresis width and changes color).

[0009] Furthermore, the method described in Japanese Patent Application Laid-Open No. 60-264285, which was previously proposed by the applicant, Contains a color-memory thermochromic dye that exhibits large hysteresis characteristics and changes color. Thermochromic materials (i.e., the shape of the curve plotting the change in color density due to temperature changes) However, when the temperature is increased from the lower side than the discoloration temperature range, the discoloration temperature When the temperature is lowered from the higher temperature side, the color change takes a very different route than when it is lowered from the higher temperature side. Type: In the room temperature range between the low temperature side discoloration point and the high temperature side discoloration point, It is possible to memorize and retain the appearance changed at a temperature above the discoloration point on the lower or high temperature side). Thermochromic image 3 is mentioned.

0010 The above-mentioned thermochromic dyes or color-memory thermochromic dyes are usually microscopic. The ink is encapsulated in a capsule and dispersed in a medium containing a water-insoluble binder. , applied as a colorant in the form of paint, etc., to the desired surface of the support (plastic) A thermochromic image 3 is formed. In addition, the above-mentioned microcapsule pigment is contained in the thermoplastic plastic. The thermochromic image 3 may be formed by kneading and melting.

[0011] In the water-erasable non-discoloring colored layer 4, the water-soluble dye is fixed to the water-soluble resin in a compatible state. Formed as a layer, or as a fixed layer with pigment dispersed in water-soluble resin I can give an example of what has been formed.

0012 The water-soluble resins mentioned above include gelatin, gum arabic, casein, and carboxylic acid. Methyl cellulose, alginic acid and its salts, polyvinyl alcohol, methyl Cellulose, polyvinylpyrrolidone-vinyl acetate copolymer, polysodium acrylate starch, polyethylene oxide, water-soluble polysaccharide, starch, hydroxycellulose ethyl hydroxycellulose, viscose, gum tragacanth, polyvinyl ester ether, polyvinylpyrrolidone and its derivatives, and other cellulose derivatives. can be done. Among them, it has moderate adhesion to plastic surfaces and moderate moisture absorption, and is suitable for low humidity conditions. Polyvinylpyrrolidone-vinyl acetate copolymer that does not cause cracks in the adhesive layer , polyvinylpyrrolidone and its derivatives are preferred.

[0013] The water-erasable non-discoloring colored layer 4 is a medium containing a resin selected from the water-soluble resins. Spray painting, printing, handwriting, etc. using ink, paint, etc. containing the above coloring material on the body It can be formed by the following means. Note that the thermochromic image 3 can be formed directly on the plastic surface of the toy base material, but A base layer 5 can be formed in advance to make the thermochromic image 3 more clearly visible. Ru. In addition, a coating layer 6 made of transparent resin is provided to cover the thermochromic image 3 to protect the thermochromic image 3. can be done.

[0014] Furthermore, a water-soluble base coat layer 7 (as described above) is provided below the non-discoloring colored layer 4. (selected from water-soluble resins) to facilitate water erasability of the non-discoloring colored layer 4. At the same time, it is possible to eliminate the non-color-changing colored layer from being erased. this kind of plastic Toys are usually formed with a satin finish to create a matte surface. However, by disposing the water-soluble base coat layer 7, it is possible to prevent fine recesses from entering. There is no residual color-changing colored layer 4, and it can be easily and completely erased with water. still, When the surface is smooth, it is not necessarily necessary to provide the base coat layer 7.

[0015] In the above structure, the water-erasable non-chromic colored layer 4 overlaps the thermochromic image 3. Or, a part overlaps with thermochromic image 3 and forms a different image as a whole, or thermochromic image 3 3 may be a combination arranged at a separate location.

[0016]

[Effect]

The water-erasable non-discoloring colored layer 4 is resistant to abrasion during distribution and handling. If the toy 1 itself is not damaged, it can be cleaned by soaking it in water or warm water, or by using a sponge or cloth. It can be easily removed by impregnating it with water and rubbing it lightly. Especially, In a system in which a water-soluble base coat layer 7 is provided, the non-discoloring colored layer 4 is It will be removed together with the skort layer 7, leaving traces of the colored material on the toy surface. Not at all.

[0017] In a system in which the non-chromic colored layer 4 overlaps the thermochromic image 3 to hide the thermochromic image 3, the ring Visualizes a non-chromatic colored image that is not affected by ambient temperature, and can be used at low or high temperatures outside of the normal temperature range. Do not expose the aspects that appear in the area unwillingly.

[0018] The non-chromic colored layer 4 may overlap a part of the thermochromic image 3, or may not overlap at all and may be separate from the thermochromic image 3. In the system installed at the location, there are various differences before and after erasing the non-color-changing colored layer 4. Make the image visible.

[0019]

[Example 1] (See Figures 1 and 6) Placed on the doll's face below the eyes, made of a flesh-colored plastic base material. The tear-shaped thermochromic image 3 is placed on a shielding member on which a tear-shaped cut-out image is placed at a predetermined position on the face. Thermochromic paint [color-memory thermochromic dye (low temperature side discoloration point: 15°C)] , high temperature side discoloration point: 30℃, 10 parts by weight of microcapsule pigment of blue←→colorless) was activated. Lil resin medium (solvent: mixed solvent of toluene and methyl isobutyl ketone) 90 weight It was formed by spray painting.

[0020] Next, 12 parts by weight of vinyl chloride-vinyl acetate copolymer was added to toluene and methyl isochloride. Dissolve in 87 parts by weight of a mixed solvent of butyl ketone, and add benzophenone ultraviolet absorber and A paint made by adding an appropriate amount of filler is sprayed on the face to reduce the thermochromic image 3. After forming the covering layer 6, 20 parts by weight of polyvinylpyrrolidone was added to ethanol. A water-soluble base coat layer 7 is applied by spraying a coating solution made by dissolving 80 parts by weight of water on the face. Formed.

[0021] On the upper surface of the water-soluble base coat layer 7 (where the thermochromic image 3 is located), polyvinyl 8 parts by weight of pyrrolidone, 15 parts by weight of white pigment (titanium oxide), 0.5 parts by weight of blue pigment 10 parts by weight of water and 66.5 parts by weight of ethanol was sprayed to form a teardrop shape. A water-erasable non-chromic colored layer 4 is formed which covers the thermochromic image 3 and blocks the visibility of the image 3. accomplished.

[0022] Lightly rub the non-discoloring colored layer 4 on the doll's face with a sponge impregnated with water. The colored layer 4 is erased to form a tear-shaped thermochromic image 3 (colored blue). Made it appear. Next, press a sponge impregnated with 40°C warm water onto the thermochromic image 3. The blue color disappeared and this state was maintained at room temperature.

[0023] The thermochromic image 3 undergoes color change due to the application of heat or cold heat such as hot water, hot air, or cold water. We were able to visualize the appearance before and after the change in a tautotropic manner at room temperature.

[0024]

[Example 2] (See Figures 1, 2, 3, 4, and 6) A pale blue-white base layer 5 is applied to the eyes of the doll, which is made of a plastic base material colored in a flesh color. At the same time, deep blue eyelashes (water-insoluble, non-discoloring colored image 8) are spray-painted ( After forming a shielding member with openings of the desired shape at appropriate locations, Thermochromic paint [color-memory thermochromic pigment (color change point on low temperature side: 17℃, color change on high temperature side) Points: Light blue←→colorless (for iris), dark blue←→, each with a color change point of 30℃ Colorless (for eyes, eyeliner, eyelashes), pink←→colorless (for eyeshadow)] The encapsulated microcapsule pigments are dispersed in a medium containing an acrylic resin binder. The thermochromic image 3 ( The iris, pupils, eyeliner, eyelashes, eyeshadow) were formed. Next, the surface of the eyes becomes pale. After forming highlights with a blue non-discoloring oil paint, the same procedure as in Example 1 was carried out. A coating layer 6 covering the pupil was formed by spray painting.

[0025] The upper surface of the coating layer 6 is coated with 75 layers of polyvinylpyrrolidone-vinyl acetate copolymer. A water-soluble base coat is applied by spraying a coating solution made by dissolving a certain amount in 25 parts by weight of ethanol. After forming the layer 7, a water-soluble paint [polyvinylpyrrolidone-vinyl acetate copolymer 10 parts by weight, 15 parts by weight of white pigment, 0.3 parts by weight of pink pigment, 10 parts by weight of water, eta 64.7 parts by weight of water-erasable non-discoloring colored layer 4. was formed.

[0026] When purchased by the user, the doll's face appears to be sleeping with its eyes closed. However, by lightly rubbing the non-discoloring colored layer 4 with a sponge impregnated with water, , the colored layer 4 can be erased and the desired eye appearance (pale blue iris, dark blue pupil, eye A thermochromic image 3 exhibiting liner, eyelashes, and pink eyeshadow was developed. next When a sponge impregnated with 40°C warm water was pressed against the thermochromic image 3, the The pigmented eyes had faded, and the eyes were closed, giving the appearance of being asleep. The above condition is at room temperature. Retained. Next, a sponge impregnated with cold water at approximately 5°C was pressed against the eye area. However, the color developed again and returned to its original appearance. The thermochromic image 3 includes hot water, hot air, and cold water. The application of heat or cold such as The phases could be visualized tautomically at room temperature.

[0027]

[Example 3] The doll's face is made of plastic material colored to match the skin's skin, and has color memory and temperature sensitivity. Colorants containing color pigments give the appearance of makeup when cooled, and the appearance of a real face when heated. A covering layer (according to Example 2) is applied to cover the colored face. After forming a water-soluble base coat layer (according to Example 2), A water-erasable non-discoloring paint (polyvinylpyrrolidone- Using vinyl acetate copolymer as the fixing resin), a Halloween Dracula image is formed. did.

[0028] If the user purchases the doll, the face of the doll will look like Dracula from Halloween. However, by lightly rubbing the image with a sponge soaked in water, the The image of Dracula could be erased, allowing the user to see him wearing makeup. Next, add warm water of about 40℃. When the impregnated sponge was pressed against the makeup-covered face, the appearance of makeup was observed. The color faded, allowing us to see his true face. The bare face appearance was maintained at room temperature.

[0029] Next, a sponge impregnated with cold water of approximately 5°C was pressed against the eye area, and the result was a relapse. The color has become brighter and the appearance of wearing makeup has returned. The face may be exposed to heat such as hot water, hot air, cold water, etc. The appearance before and after the change is observed in the room temperature range by repeatedly causing changes in color development and fading by applying cold heat. I was able to visualize it in a tautomorphic manner.

[0030] As described above, a system in which a thermochromic image and a water-erasable non-chromatic colored image are combined is shown in the embodiment. It is not limited to, but can be applied to a wide variety of applications.

[0031] For example, if you use a dog toy [which reversibly changes color from white to black due to thermal discoloration] [Provide a muddy appearance image with non-discolorable paint], Traveling toy [Provide a muddy appearance with non-discolorable paint] Military truck with more camouflage pattern←→White civilian truck, water erasable red cross mark formed with red non-tarnishing paint], doll Face←→The face changes into a smiling face, and the face changes into a clown using water-erasable non-discoloring paint. ], dolphin toy [which reversibly changes from blue to white due to thermal discoloration], A dolphin with an anthropomorphic face painted with water-erasable, non-discoloring paint. Formation], etc., and each thermochromic image is a thermochromic dye or a thermochromic pigment with color memory. It can be formed using coloring materials containing pigments.

[0032]

[Effect of the idea]

As mentioned above, the thermochromic figurative toy of the present invention changes color by heating or cooling. In addition to the image, a water-erasable, non-tarnishing colored layer is formed on the surface of the toy. In a system in which a color-changing colored layer is superimposed on a thermochromic image to hide it, the non-chromic colored layer The visual perception of the thermochromic image is obstructed, making it difficult for customers at stores and when purchasing products to may reveal an undesirable appearance that does not meet the discoloration requirements of a specific product concept. No way. Further, the non-color-changing colored layer may partially overlap or non-overlap the thermochromic image. In systems where thermochromic images and different images are installed, various images are displayed in addition to thermochromic images. Moreover, the non-discoloring colored layer is added during the distribution stage of the product and during normal handling. It will not be damaged by scratches etc., but it can be easily erased with water, and after water erasing, it will not be damaged by scratches etc. You can play with a thermochromic image similar to that by changing its color due to temperature changes, creating a variety of aspects. It is possible to provide a thermochromic figurative toy that exhibits the following properties.
