BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing an embodiment of a thermochromic mask pack including an image portion formed by a pigment composition for a thermochromic mask pack of the present invention, wherein a color reversibly changes in accordance with a temperature change . For example, in the case of the mask pack (a), the hue indicates the color at an ambient temperature of 10 ° C. In the case of the mask pack (b), the hue indicates the hue at an ambient temperature of 25 ° C, And thus the temperature of the mask pack can be visually confirmed.

Hereinafter, the pigment composition for the thermochromic mask pack of the present invention and the thermochromic mask pack containing the same will be described in more detail.

The pigment composition for a heat-discoloring mask pack is a pigment composition printed on a mask pack to exhibit various color changes depending on temperature. The pigment is a heat-discoloring pigment whose color changes depending on temperature together with a coloring pigment, .

Among the above pigments, the color pigments can be selectively used as required among inorganic pigments and organic pigments. For example, white pigments such as white pigments, zinc pigments, zinc sulfide, and titanium dioxide, Green pigments such as chromium oxide, pyridine and chrome green, yellow or red pigments such as chrome yellow, titanium yellow, yellow iron oxide, molybdate orange and cadmium pigments, iron black, titanium black and carbon black Metal pigments such as black pigment, aluminum powder, bronze, and the like, and pearl pigments such as mica. Examples of the organic pigments include, but are not limited to, azo pigments, indanthrone pigments, indigo pigments, thioindigo pigments, phthalocyanine pigments, dioxazine pigments, and pyrrolopyrrole pigments.

On the other hand, the above-mentioned zeolite pigment is a temperature-sensitive pigment which changes in color depending on the temperature. As the pigment reaches a reference temperature, the color begins to disappear. When the reference temperature is reached, the color becomes transparent. Or reversible or irreversible, depending on whether or not it is returned to < RTI ID = 0.0 > a < / RTI > The preferred range of the temperature change in the present invention is 20 占 폚 to 45 占 폚, more preferably 30 占 폚 to 40 占 폚.

The zeolite pigment included in the pigment composition for a thermochromic mask pack of the present invention is preferably a reversible temperature-sensitive pigment which can maintain or lose its original hue according to temperature, wherein the zeolite pigment is a metal complex salt dye , Cholesteric liquid crystal, and meta-color. However, the present invention is not limited thereto. As the metal complex salt dye, it is preferable to use titanium dioxide.

On the other hand, the zeolite pigment preferably contains an iodide of a heavy metal such as Hg, Ag, Cu, Pb or a complex thereof in an inorganic compound system. At this time, for example, the cyan pigment having a pigment composition of Ag ₂ HgI ₄ and Cu ₂ HgI ₄ can be discolored at a temperature of 50 ° C and 70 ° C, respectively, and in case of mixing, a discoloration temperature can be set between 50 ° C and 70 ° C .

Further, the zeolite pigment may include organic compounds such as spiropyran and the like, and when heated and melted, it can be reversibly changed from colorless to colored.

On the other hand, the zeolite pigment is, for example, a zeolite pigment commercially available from Camell Chemical Company, and is a yellow pigment such as yellow, orange, magenta, rose red, sky blue, colors such as dark blue, fast blue, violet, Turkish blue, green, and black may be used, but the present invention is not limited thereto.

On the other hand, by using the pigment containing the colored pigment and the zeotropic pigment, it is possible to produce a mask pack capable of changing the color depending on the ambient temperature.

For example, when the zeolite pigment is a pigment exhibiting an intrinsic color at 25 ° C or higher, the mask pack having the intrinsic hue in a state where the color pigment and the zeolite pigment are mixed, So that only the color by the colored pigment is produced.

In such a state, when the user uses the mask pack, the mask pack rises to 25 ° C or higher under the influence of the body temperature of the user, and a distinctive color mixed with the coloring pigment is displayed .

As another example, in the case of a thermochromic mask pack comprising a pigment in which a color pigment and a zeotropin pigment are mixed such that the zeolite pigment exhibits an intrinsic color only at less than 25 캜, the zeolite pigment is colorless at a temperature of 25 캜 or higher, Only the color by the mask pack is expressed in the mask pack.

That is, when the user uses the mask pack to raise the temperature of the mask pack to a temperature of 25 ° C or more due to the body temperature of the user, the color of the color pigment is directed on the mask pack while the unique color of the zeolite pigment disappears. When the user using the mask pack is exposed to an environment of less than 25 캜, the color represented by the zeolite pigment is expressed, so that the mixed color of the color pigment and the zeolite pigment is produced, The same effect as using a pack can be obtained.

The pigment is preferably contained in an amount of 0.5 to 15% by weight, more preferably 1 to 10% by weight, based on the total weight of the pigment composition for a thermochromic mask pack. If the content of the pigment is less than 0.5% by weight, it is difficult to clearly show the color on the base sheet after printing. If the content is more than 15% by weight, the pigment is hardly dispersed in the composition.

In particular, when two or more colors of zeotropic pigments having different coloring temperatures are mixed and used at a certain ratio by using the zeotropic pigment, the color of the mask pack varies in accordance with the temperature around the user And can produce a fantastic beauty.

In particular, the color pigment and the zeotropic pigment contained in the pigment are preferably contained in a weight ratio of 0: 100 to 40:60, more preferably 0: 100 to 20:80. That is, the coloring pigment may contain only the zeolite pigment, and when the coloring pigment and the zeolite pigment are mixed, the weight ratio is 0: 100 to 40:60. When the coloring pigment and the zeolite pigment are removed, have.

On the other hand, due to the pigment composition for a thermochromic mask pack, the hue expressed in the thermochromic mask pack can be expressed as a mixture of a zeotropic pigment, a colored pigment alone, or a colored pigment and a zeotropic pigment, Can be expressed over a range of L = 0 to 100, a = ± 127, b = ± 127 in the CIELAB color space system as shown in FIG. 2. For example, if L is 70 or more It is preferable that the mask pack is a variable mask pack. In addition, color can be expressed by a zeolite pigment, that is, in a transparent manner. Thus, when a colored pigment is mixed with a zeolite pigment, the color of the colored pigment can be expressed.

On the other hand, the pigment composition for a heat-discoloring mask pack is preferably a water-soluble polymer which comprises at least one member selected from the group consisting of a polymer containing a urethane group, a copolymer containing a urethane group, a polymer containing an acrylic group, .

Furthermore, the water-soluble polymer is preferably contained in an amount of 1 to 30% by weight, more preferably 10 to 20% by weight, based on the total weight of the pigment composition for a thermochromic mask pack. If the content of the aqueous polymer is less than 1% by weight, the pigment composition for the thermochromic mask pack may have poor dispersibility, and the composition layer may be separated. When the content of the aqueous polymer is more than 30% by weight, There may be a problem that the viscosity of the composition increases and the drying speed of the pigment composition increases.

Further, it is preferable that the pigment composition for the thermochromic mask pack further comprises at least one selected from the group consisting of a surfactant, a bactericide, a viscosity adjusting agent, a pH adjusting agent, a buffer and an antioxidant, And it is possible to add the components necessary for manufacturing the mask pack by forming the image portion on the base sheet.

At this time, the dispersant is preferably contained in an amount of 0.1 to 5% by weight, more preferably 1 to 3% by weight based on the total weight of the pigment composition for a thermochromic mask pack. When the content of the dispersant is less than 0.1% by weight, the dispersibility of the composition may be deteriorated and the composition layer may be separated. When the content of the dispersant is more than 5% by weight, the dispersibility of the pigment may be poor.

The wetting agent contained in the pigment composition for a thermochromic mask pack may be at least one selected from the group consisting of ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, tetraethylene glycol, 2-methyl-2,4-pentanediol, Diethylene glycol mono-methyl ether, propylene glycol mono-methyl ether, propylene glycol mono-ethyl ether, propylene glycol mono-diethyl ether, diethylene glycol mono-diethyl ether, diethylene glycol mono- At least one compound selected from the group consisting of triethylene glycol mono-methyl ether, triethylene glycol mono-methyl ether, triethylene glycol mono-ethyl ether, diethylene glycol di-methyl ether, diethylene glycol di-ethyl ether, diethylene glycol monobutyl ether, glycerol and sugar .

The wetting agent is preferably contained in an amount of 10 to 50% by weight, more preferably 20 to 40% by weight, based on the total weight of the pigment composition for a thermochromic mask pack. When the content of the wetting agent is less than 10% by weight, the drying speed of the pigment composition is increased. In forming the image portion on the base sheet using the inkjet, drying in the nozzle in the inkjet head may cause problems such as nozzle clogging When the content is more than 50% by weight, the viscosity of the composition is increased and the dispersibility is disadvantageously lowered.

The solvent is preferably contained in an amount of 30 to 70% by weight, more preferably 40 to 50% by weight, based on the total weight of the pigment composition for a thermochromic mask pack. The solvent may include water, such as purified water or deionized water, and may further include a water-miscible organic solvent mixed with water, but is not limited thereto.
