Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a color memory toy, in particular, which can be changed from one aspect to another by the user using appropriate heating or cooling means, and which The present invention relates to a toy with dual characteristics that can select one of the above aspects and maintain it at room temperature.

BACKGROUND ART Regarding this kind of toy that exhibits duality due to temperature changes, it has been proposed that the surface color changes before and after a predetermined temperature (for example, Utility Model No. 60-102090). , Japanese Patent Publication No. 60-228141,
61-188481, 61-196988), but of the two states before and after the change, only one specific state can exist in the normal temperature range. In other words, the other state is maintained as long as the heat or cold required to bring it about is applied, but when the heat or cold is no longer applied, it returns to the state it exhibits at room temperature. It is something.

Problems that the invention aims to solve This invention has two aspects: it not only changes the color of the surface due to temperature changes, but also allows you to freely select either the appearance before or after the change and maintain that appearance at room temperature. The idea is to provide toys that show sexuality.

Means for Solving the Problems The color memory toy of the present invention further exhibits a hysteresis characteristic depending on temperature changes on the surface of at least a portion of the toy, which itself has one aspect, so as to change the color between a colored state and a colorless state or a colored state. It is a composition in which colors are applied using a coloring material in the form of ink, paint, paint, etc. containing a quasi-reversible temperature-sensitive dye that exhibits chromatism between two colored colors.

The semi-reversible temperature-sensitive dye was previously proposed by the present applicant (Japanese Patent Application No. 121267/1982, Japanese Patent Application No. 264285/1983).
A reversible thermosensitive recording composition that has been prepared is preferably used.

The composition comprises: (a) an electron-donating color-forming organic compound, (b) an electron-accepting organic compound that causes the component (a) to develop color, selected from compounds having a phenolic hydroxyl group, aromatic carboxylic acids, etc. (c) A composition consisting of a homogeneous compatible solution containing three essential components of carboxylic acid ester compounds selected from the compound groups shown in (1) to (7) below.

(1) Carboxylic acid ester containing a substituted aromatic ring in the molecule, (2) Carboxylic acid containing an unsubstituted aromatic ring and 10 carbon atoms
(3) Carboxylic acid esters containing a cycloalkyl group in the molecule; (4) Esters of fatty acids with 6 or more carbon atoms and unsubstituted aromatic alcohols or phenols; (5) 8 carbon atoms. (6) Esters of dicarboxylic acids and aromatic alcohols or branched aliphatic alcohols, (7) Benzyl cinnamate, heptyl stearate, didecyl adipate, dilauryl adipate, dimyristyl adipate, dicetyl adipate,
Distearyl adipate, trilaurin, trimyristin, tristearin, dimyristin,
Distearin.

The semi-reversible thermosensitive dye is preferably microencapsulated and used in particulate form.

The hysteresis characteristic is that the shape of the curve plotting the change in coloring temperature due to temperature change is different depending on whether the temperature is changed from a lower temperature to a higher temperature than the discoloration temperature range or vice versa. Combining both curves creates a loop (9th
(see figure). Among the matching points of both curves at both ends of the loop, if the temperature of the matching point on the low temperature side is A, and the matching point on the high temperature side is B, then in the semi-reversible temperature-sensitive dye used in the present invention, A is ice or cold water. B indicates the temperature obtained from familiar objects such as body temperature, bath water temperature, or hair dryer, that is, approximately 27 to 90 degrees Celsius. The temperature range (hereinafter referred to as the two-color retention temperature range) in which both the colored and colorless phases or the colored 1 and colored 2 phases can coexist is within the room temperature range, and in particular, from about 10°C to Those in the normal temperature range of 35°C are preferably selected.

Furthermore, regarding the semi-reversible temperature-sensitive dyes, there are those with different colors, those whose two-color retention temperature range is within the room temperature range but different from each other, and special examples of the above, such as those where one semi-reversible temperature-sensitive dye has a two-color retention temperature range of the other. Combinations of different types, such as combinations that are broader than and include those of quasi-reversible temperature-sensitive dyes, can be applied to the same surface area or applied to different surface areas, resulting in a wide variety of effects. To impart compatibility between patterns and design aspects to toys.

This semi-reversible temperature-sensitive dye is dispersed in a suitable vehicle and used as a colorant in the form of ink, paint or paint to color a desired location on the surface of a figurative toy. Of course, the above treatment may be performed on the surface of the member before it is incorporated into the toy.

Function: If the part of the figurative toy to which the semi-reversible temperature-sensitive dye is coated is colorless (the underlying coloring appears), the surface is once cooled to below temperature A to make it colored, and then allowed to cool to room temperature. If returned, the aspect of the colored state is maintained at room temperature.

In addition, once the surface portion in the colored state is
If the material is heated above the temperature to make it colorless and then returned to room temperature, the colorless state will be maintained at room temperature. The same holds true for the aspect of tautism between colored 1 and colored 2.

In this way, the figurative toy of the present invention has the function of allowing the user to select one aspect from two types as desired, retain that aspect, and then change to another aspect and retain it. do. In this case, if heat or cold is applied only to a part of the application area,
Only that part will appear to have changed.

Furthermore, if different types of quasi-reversible temperature-sensitive dyes are applied to different parts of the surface, the overall pattern or design changes as each part changes.

Applications of the above functions include changes between two phases in dolls: a face with a bare face and a face with makeup, a face with normal makeup and a face with heavy makeup, and generally a single color and a camouflage color, and design 1. and design 2, toys with surfaces exhibiting tautism between plain color and arbitrary design, colored 1 and colored 2, colored 1 and colored 1/colored 2 patterns (figurative toys and dolls such as vehicles, animals, monsters, dinosaurs, etc.) Clothes, etc.), specific examples include animal toys that exhibit tautotropism between each phase, such as a horse and a striped horse, a polar bear and a panda, and each aspect is maintained at room temperature.

Examples Example 1 A doll made of polyvinyl chloride resin with a normal face makeup, that is, lips colored pale pink, cheeks pale vermilion, and eyelids pale purple, changes to blue and colorless due to temperature changes. (A point 10℃, B point
32℃), purple colorless (A point 10℃, B point 32℃), and pink colorless (A point 10℃, B point 32℃) Contains semi-reversible temperature-sensitive dyes L, M, and N, respectively. Paints L', M', and M' were spray-painted on the lips, cheeks, and eyelids, respectively, and after drying, a color memory doll with a dual-faced face was obtained.

The quasi-reversible temperature-sensitive dyes L, M, and N each have the following compositions, and each of the three components is mixed and melted to form a homogeneous compatible solution.

In producing the paint, the temperature-sensitive dye was used in the form of microcapsules encapsulated in an epoxy resin film by a known interfacial polymerization method.

Composition of semi-reversible thermosensitive dye L (parts by weight) 3-(4-diethylamino-2-ethoxyphenyl)-3-(1-ethyl-2-methylindol-3-yl)-4-azaphthalide 3 parts Bisphenol A 10 parts Neopentyl stearate 100 parts Composition of semi-reversible thermosensitive dye M (parts are parts by weight) 3-(4-diethylamino-2-ethoxyphenyl)-3-(1-ethyl-2-methylindole- 3-yl)-4-azaphthalide 1 part 1,2-benz-6-diethylaminofluorane 2 parts Bisphenol A 12 parts Neopentyl stearate 100 parts Composition of semi-reversible thermosensitive dye N (parts by weight) 1,2 -Benz-6-diethylaminofluorane 3 parts Bisphenol A 12 parts Neopentyl stearate 100 parts After warming the doll's face with your hands to make it look like a face with normal makeup, place it at room temperature of about 25℃ for about 10 minutes. When cooled with cold water at ℃, the lips changed to dark blue, the cheeks to dark purple, and the eyelids to dark pink, giving the appearance of a face with psychedelic makeup, and this appearance was observed in the temperature range of 14℃ to 29℃. was held stably.

Next, when she warmed her face with her hands again, the psychedelic makeup disappeared and her face changed to a face with normal makeup. Each time this operation was repeated, the psychedelic makeup phase and the normal makeup phase showed compatibility, allowing the player to play with it over and over again. Moreover, the above-mentioned changes could be made only in any part of the lips, cheeks, or eyelids.

Example 2 A pale blue plain polyester fabric was colored green colorless (A point 8°C, B point 35°C), red colorless (A point 8°C, B point 35°C), orange colorless (A point 8°C, Using screen printing inks P', Q', and R' containing semi-reversible temperature-sensitive dyes P, Q, and R that change at point B (35°C), a spotted pattern is screen printed, and this fabric is made into costumes. By attaching it to a doll, we obtained a color memory doll whose costume shows duality.

Heat this doll's costume with a hair dryer,
It appeared to be wearing a plain light blue costume at a room temperature of approximately 20 degrees Celsius. Next, when this doll was placed in the refrigerator and cooled, the plain costume changed to a light blue background with green, red, and orange spots, and this appearance changed from 15℃ to 30℃.
It was maintained stably in the temperature range of .

Next, when the doll was heated again with a hair dryer, the spotted pattern disappeared and the doll appeared to be wearing a plain light blue costume. Each time this operation was repeated, the costume changed between a solid color and a spotted pattern, allowing the user to play with it over and over again.

Example 3 A paint containing a semi-reversible temperature-sensitive dye that changes to red and yellow depending on temperature changes (A point 10℃, B point 32℃) was spray-painted on the surface of an ABS resin miniature car.
After drying, a color memory miniature car with a dual-sided body was obtained. This is shown in Figures 1 and 2.

Warm the body of this miniature car by hand for about 24 hours.
It was made to have a yellow body shape at room temperature (the shape shown in FIG. 1). Next, when the body was cooled to below 10°C using cold spray, it changed to a red body, and this appearance remained stable in the temperature range of 15°C to 30°C.

Next, when we heated only the roof part of the body with our hands, only the roof part changed from red to yellow, giving the appearance of a two-tone yellow and red body (as shown in Figure 2). When I further warmed the entire body with my hands, it changed from a yellow/red two-tone color to a yellow body. Each time this operation was repeated, the game exhibited compatibility between red, yellow, and a yellow/red two-tone color of an arbitrary design, allowing the player to play the game over and over again.

Example 4 A doll made of polyvinyl chloride resin and having a face as shown in Figure 3 was given a green and colorless pupil portion 3' of the eyeball (point A: 10°C, point B: 30°C) as shown in Figure 4. Other parts 3 are dark brown and colorless (point A 10℃, point B 30℃)
°C) and the eyebrow part 3″ is brown and colorless (A point 10 °C,
A color memory doll with a dual-faced face was obtained by applying paint containing semi-reversible temperature-sensitive dyes that exhibit changes in temperature (B point 30°C).

FIG. 5 shows an enlarged sectional view of the eyeball part, and FIG. 6 shows an enlarged sectional view of the eyebrow part. In the figure, 1 is the facial base material, 2, 2' is the non-discolored image, 3, 3',
3'' is a semi-reversible temperature-sensitive dye layer.

If you cool this doll's face to a temperature below 10℃,
If you press a towel containing hot water of 30°C or higher over one eye, the appearance will appear with both eyes open as shown in the fourth figure, and if you press the towel containing hot water over one eye, only one eye will become closed and winking, and if you further press the towel over the entire face, the appearance shown in the third figure It appears to be asleep with both eyes closed. All aspects were maintained at room temperature, and changes between each aspect were repeatedly reproduced.

Example 5 A mark was drawn with a brush using multi-colored paint on the side of a miniature car (truck), and a pink colorless (point A: 10°C, point B: 35°C) was painted on the entire surface of the mark.
Paint 1 containing a semi-reversible temperature-sensitive dye that exhibits a change in temperature is applied, and the surface is further coated with colors ranging from dark green to colorless (A point 10℃, B point
Paint 2 containing a semi-reversible temperature-sensitive dye with a temperature of 35° C.) was applied so as to partially overlap the coated surface to obtain a miniature car with a two-sided mark.

FIG. 7 shows an enlarged sectional view of the mark portion. In the figure, 1 represents the base material of the minicar, 2 and 2' represent the paint forming the mark, and 3 represents the paint 1 and 3' the paint 2, respectively.

This miniature car displayed a mark when exposed to temperatures above 35 degrees Celsius, and this mark remained even when the car was returned to room temperature. Next, when it was cooled to a temperature below 10 degrees Celsius, a different mark was displayed, and this mark also remained in the room temperature range, allowing the player to play by repeating this change.

Example 6 A colorful pattern was offset printed on the surface of art paper, and a colorless black (A point 10℃,
A simulated instant photograph having duality was obtained by screen printing with an ink containing a semi-reversible temperature-sensitive dye exhibiting a change in point B (30° C.).

FIG. 8 shows an enlarged cross-sectional view of the simulated instant photograph. In the figure, 1 represents the base material, 2, 2', and 2'' represent the ink constituting the pattern, and 3 represents the semi-reversible temperature-sensitive dye layer, respectively.

This simulated instant photo becomes entirely black when cooled to below 10℃, remains black even when returned to room temperature (15℃ to 28℃), and disappears when exposed to temperatures above 30℃, creating a colorful pattern. It becomes the appearance. This pattern was maintained at room temperature and could be played by repeating the changes described above.

Effects of the invention As mentioned above, the present invention is capable of changing the appearance of part or all of the surface of a toy using heat or cold sources found in daily life, and at the same time retaining the desired appearance at room temperature. By giving each part of the doll, such as the doll's face, hair, nails (manicure), costumes, accessories, shoes, hats, etc., a dual nature, you can create several different versions of the toy without having to replace those parts. It can be used as a toy that exhibits various aspects. In this way, the present invention provides users with a variety of ways to play with a single toy, and adds high added value to the toy.
