The thermochromic patch comprises a pigment layer and an adhesive layer for easily affixing the pigment layer to fabric, paper, or a diaper. A color formation layer is formed using ink containing a thermochromic pigment in an affixing patch of the patch or using a PU coating mixture containing the thermochromic pigment to form a desired pattern or a desired type according to a temperature of the affixing patch.

Description

[0001] The present invention relates to a diaper patch for thermo-sensitive use, and more particularly,

The present invention relates to a disposable diaper which is mainly used by severely ill patients. The conventional diaper has a difficulty in a proper replacement period because the caregiver has a problem of directly grasping the feces sign of the patient at the time of nursing care. The present invention is a thermosensitive patch using a thermochromic capsule which senses a change in color visually and eliminates the risk of a patient.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sticker having a pigment layer,

To a patch for a severe patient diaper comprising a thermochromic dye layer in which a printed picture or text using capsule pigment appears or disappears according to a change in temperature.

A compound constituting the coloring matter layer is a coloring material which changes color when a set temperature is reached. Reversible material that returns to its original color when it deviates from the set temperature, and irreversible material that does not return to its original color after it has changed. Microcapsule powder type and slurry form sealed in capsules under two substances inducing chemical action do

It has a milky white color when it reaches the set temperature, it is well dispersed in common organic solvents, and when dispersed in water-soluble materials, it is used dispersant. There is a product which changes to white, and when the temperature exceeds the reference temperature, it is changed into red, black, green, blue, etc. At the low temperature, it is white, but when it is above the set temperature, it becomes transparent and does not return to its original color. Three types of Sion ink are KONOSEI, KOREA STERIC liquid, and METAMO color. From 1937 to 1941, a large number of irreversible Zion materials were discovered, named as Telomolor, and after the Second World War, they were further upgraded by BASF. In Japan, on the other hand, a paint using low-grade mercury complex salt was released in Japan under the name of chameleon. Since 1937, it has been studied mainly as a military use at the Institute of Chemical and Biological Research. In 1965, special printed matter, table top thermometer and pendant using liquid crystal were developed and started to be put on the market. Thus, in 1972, Sion ink, which is based on the electron transport mechanism by thermal equilibrium, was started among polar compounds of electron donors and electron acceptors, and for the first time, a dye-based color and discolor clear Sion ink was developed. The principle of discoloration is based on the change of crystal structure - PH variation - dehydration - pyrolysis, solid phase reaction - electron donor - acceptance of electron acceptor in a specific atmosphere - optical change according to crystal structure change. PU coating mixed with pigments to prevent the printed material from appearing, and when the temperature reaches a certain temperature, the color of the applied Zion ink disappears, so that the bottom figure or type appears.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art as described above, and it is an object of the present invention to provide a printing method using a printing ink, The characteristic feature of the present invention is that, in the case of a severely handicapped person, the feces can not be independently solved, and the caregiver or the caregiver can print the patches with the heat discoloration of the pigment layer It is easy to grasp the replacement time of the diaper through the typeface and the figure. The patch may be formed by printing with the ink prepared by applying the thermochromic pigment to the patch of the patch, or by coating the microcapsule PU mixture liquid containing the pigment, The thermochromic pigment is usually colorless. However, the coloring agent may react with a color developer to form a color developing electron-donating dye and a color developing agent. The coloring agent is then mixed with a higher temperature fatty acid alcohol The thermochromic pigments are classified into inorganic pigments and organic pigments. Most of the inorganic pigments are compounds containing heavy metals, and the fastness (light resistance, weatherability) is excellent However, there is a problem with its stability, and both the crystal type and the microcapsule type The organic pigment has a disadvantage in terms of price and fastness in the case of the thermochromic liquid crystal type, whereas the microcapsule type has a lower temperature and sensitivity than the liquid crystal type, but is very economical in terms of price, In the case of using a microcapsule type having a size of 2 to 10 mu m in Zion ink, it is very vulnerable to extreme shock, and it is necessary to avoid contact with high heat and organic solvent Soluble ink, and it is preferably dried at a temperature of 110 ° C or lower. When the thermochromic pigment is used to produce a sion ink, 0.1 to 5 parts by weight of a thermochromic pigment, 10 to 20 parts by weight of a resin such as polyvinyl alcohol, and 80 to 85 parts by weight of water are compounded Facts, so I do not mention it anymore. The printed pattern printed on the coloring layer is characterized in that various character patterns printed on the attachment foil are formed to disappear as the temperature of the attachment foil increases, as shown in Fig. The printed pattern printed on the color developing layer may be formed so that the printed pattern printed on the generation layer appears according to the temperature rise of the attaching cloth. And may be formed so as to appear or disappear according to the temperature rise of the attaching cloth.

Structure and function of the invention

In order to achieve the above-mentioned object, a sticker having a thermochromic pigment according to the present invention includes a pigment layer to which a thermochromic pigment is adhered, a fabric or paper to which the pigment layer is adhered, And a layer of a thermochromic dye for expressing a desired printing figure or type in accordance with the temperature of the adhesive patch. The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. A patch having the thermochromic dye layer according to the present invention will be described.

1 is a cross-sectional view of a patch having a thermochromic dye layer according to an embodiment of the present invention. 1, the patch according to the present invention includes a pigment layer 10 to which a thermochromic pigment is adhered, an attachment foil 20 to which the pigment layer is adhered, And an adhesive layer (30). In the present invention, the present invention does not claim the scope of the rights of the composition and the manufacturing method of the thermosensitive pigment, but adds a specific identification function for diapers to a commercially available patch.

As described above, according to the sheet type patch having the thermochromic dye layer according to the present invention, when the temperature of the patch rises, there is an effect that it is possible to know the proper replacement timing through the figure or type printed on the patch.

[0001] The present invention relates to a sheet type patch comprising a thermochromic dye layer according to the present invention, and more particularly, to a sheet type patch comprising a thermochromic dye layer according to the present invention, Fig. 2 is a view showing another embodiment of a sheet type patch having a thermochromic dye layer according to the present invention;

The characteristic feature of the present invention is to obtain a peculiar effect by adding a pigment layer to an existing patch, wherein the pigment layer is formed by printing ink with a thermochromic pigment applied to the patch (fabric or paper) of the patch, The thermochromic pigment is formed by coating with a PU coating mixture to which a thermochromic pigment is applied and a desired printed pattern is formed on the coloring layer according to the extent of the heat of the adhesive foam absorbing the heat of the feces. , A functional pigment which is prepared by combining an electron donating dye and a color developing agent which react with a color developing agent and then dissolving it in higher fatty acid alcohols for temperature sensing, thereby reversibly discoloring by temperature. The thermochromic pigment is an inorganic pigment Organic pigments are used in isolation. Most of the inorganic pigments are compounds containing heavy metals and have fastness (light fastness, weather resistance) Although both the crystal type and the microcapsule type are more expensive than the organic type, the organic pigment has a disadvantage in terms of the price and fastness in the case of the thermochromic liquid crystal type, whereas the microcapsule type Temperature and sensitivity are lower than that of liquid crystal type, but it is very economical in terms of price and has a merit that the temperature range can be selectively manipulated to some degree. The Zion ink according to the present invention can be prepared by selecting a thermochromic pigment whose color changes from color to colorless reversibly at 25 ° C to 45 ° C. The printing pattern printed on the coloring layer is as shown in FIG. Similarly, various character patterns printed on the attachment foil are formed to disappear in accordance with the temperature rise of the attachment foil. 3, the print pattern printed on the color developing layer may be formed in a pattern that indicates the replacement timing of the patch, Or may be formed to disappear as the temperature rises.
