Glitter powder is a powder made of reflective particles, and it reflects light from various angles to realize a shiny appearance on the surface of an object. It is widely used in various fields such as interiors.

Conventional glitter films are made by applying an oil-based adhesive to a support first, and then spraying and attaching a single-colored glitter powder on the surface of the applied oil-based adhesive, but this method has the disadvantage that its utilization is limited to a single color. Have.

In addition, the conventional method of manufacturing a glitter film has structural limitations in that the surface is hard and elasticity is inferior after manufacturing because the adhesion of the glitter powder is made by an oil-based adhesive, and the absorption and adhesion of ink due to the oil-based adhesive during printing and transfer. This is very low, and when characters, patterns, and designs are implemented on the glitter film, ink is smeared or erased, and the light fastness and washing fastness are remarkably deteriorated.

In addition, the conventional oil-based adhesive applied to the glitter film has a disadvantage that is harmful to the human body by generating harmful substances such as formaldehyde.

Accordingly, 1) the surface feel and smoothness of the glitter particles can be improved, 2) the adhesion of the glitter powder can be increased to prevent peeling, and 3) the glitter film to increase the adhesion with the printing and transfer ink. There are various studies on the Korean market.

FIG. 4 is an exemplary view for explaining an aqueous binder manufactured through the manufacturing step of the aqueous binder of FIG. 2.

The aqueous binder manufacturing step (S20) is a process step of manufacturing an aqueous binder for attaching the glitter powder to the hot melt film 3.

At this time, the water-based binder is used not only to increase the adhesion of the glitter powder 7, but also can increase the absorbency and adhesion of ink, and has the advantage of improving the elasticity, smoothness and surface feel of the glitter powder 7. .

In addition, the aqueous binder manufacturing step (S20), as shown in Figure 4, aqueous solution (21) 32.0 ~ 55.0% by weight, the first additive (23) 11.0 ~ 19.0% by weight, glycerin (24) 0.5 ~ 2.0% by weight With, surfactant (25) 1.0 to 6.0 wt%, dimethyl sulfoxide (26) 0.1 to 4.0 wt%, acrylic acid (27) 0.1 to 2.0 wt%, butyl acrylic acid-2-hydroxyethyl acrylic acid-methyl acrylic acid An aqueous binder 20 is prepared by mixing 10.0 to 15.0% by weight of the copolymer (28) and 10.0 to 20.0% by weight of the second additive 29.

The first additive 23 is made of sodium dodecylbenzene sulfonate, sodium dodecyl sulfate, or a mixture of both, and 11.0 to 19.0% by weight based on the total weight in order to increase the adhesion of the hot melt film 3 and the glitter powder 7 It is contained as. At this time, if the content of the first additive 23 is less than 11.0% by weight, the adhesiveness of the hot melt film 3 and the glitter powder 7 decreases, and if the content exceeds 19.0% by weight, the glitter powder 7 The hardness of is excessively increased, resulting in cracks.

Glycerin (24) is 0.5 to the total weight of the aqueous solution (21) and components (22), (23), (25), (26), (27), (28), (29) to increase the mixability. It is contained in 2.0% by weight. At this time, if the content of the glycerin 24 is less than 0.5% by weight or exceeds 2.0% by weight, the blendability of the components is poor, causing a problem that the glitter powder 7 does not implement the desired function.

Surfactant (25), like glycerin (24), is a mixture of aqueous solution (21) and components (22), (23), (25), (26), (27), (28), (29). It has the purpose of increasing, and is contained in an amount of 1.0 to 6.0% by weight based on the total weight. At this time, if the content of the surfactant 25 is less than 1.0% by weight or exceeds 6.0% by weight, the blendability of the components is poor, causing a problem in that the glitter powder 7 does not implement a desired function.

Acrylic acid 27 is contained in an amount of 0.1 to 2.0% by weight based on the total weight in order to improve the color clarity at the time of printing and transfer, as well as light fastness and washing fastness. At this time, if the content of the acrylic acid 27 is less than 0.1% by weight, the content of the acrylic acid 27 is excessively small, and clarity, washing fastness, and light fastness cannot be improved.If the content exceeds 2.0% by weight, acrylic acid 27 ) Content is excessively increased, causing a problem in that the color changes due to sunlight.

Butyl acrylic acid-2-hydroxyethyl acrylic acid-methyl acrylic acid copolymer (28) has the purpose of enhancing the adhesiveness of the glitter powder (7), and at the same time increasing color clarity, washing fastness, and light fastness, and is 10.0 to the total weight. It is contained in ~ 15.0% by weight. At this time, if the content of the butyl acrylic acid-2-hydroxyethyl acrylic acid-methyl acrylic acid copolymer (28) is less than 10.0% by weight, the adhesiveness, color clarity, washing fastness and light fastness will fall, and if the content is 15.0% by weight, If it exceeds, the adhesiveness is poor, but there is a problem that color sharpness, washing fastness, and light fastness are deteriorated.

The second additive (29) is a urethane binder, an acrylic binder, or a mixture of a urethane binder and an acrylic binder, and contains 10.0 to 20.0% by weight of the total weight for the purpose of enhancing adhesion, color clarity, washing fastness and light fastness. do. At this time, if the content of the second additive 29 is less than 10.0% by weight, adhesiveness, color clarity, washing fastness, and light fastness are deteriorated, and if the content exceeds 20.0% by weight, adhesion is good, but color clarity, There is a problem that the fastness to washing and the fastness to sunlight are poor.

That is, in the aqueous binder manufacturing step (S20) of the present invention, the containing components are blended in an appropriate amount, specifically, 32.0 to 55.0 wt% of the aqueous solution 21, 11.0 to 19.0 wt% of the first additive 23, and glycerin (24 ) 0.5 to 2.0% by weight, surfactant (25) 1.0 to 6.0% by weight, dimethyl sulfoxide (26) 0.1 to 4.0% by weight, acrylic acid (27) 0.1 to 2.0% by weight, and butyl acrylic acid-2-hyde Glitter powder (7) and hot melt film by mixing and mixing 10.0 to 15.0 wt% of oxyethyl acrylic acid-methyl acrylic acid copolymer (28) and 10.0 to 20.0 wt% of the second additive (29) to prepare an aqueous binder 20 (3) It improves the adhesion of (3), improves color clarity, wash fastness, and light fastness during printing and transfer, and can expect the purpose and effect to facilitate separation of printing and transfer paper.

In other words, conventionally, as an oil binder is used as a binder for fixing the glitter powder 7, ink is not well absorbed, and the elasticity, smoothness and surface feel of the glitter powder 7 are low, but the present invention In the following, the problem of using the conventional oil-based binder can be remarkably solved by applying an aqueous binder as a binder for fixing the glitter powder 7.

In addition, when the glitter powder is simply bonded using only the adhesive binder, the phenomenon that the glitter powder is separated by external shock and vibration occurs, but in the present invention, the adhesive layer 5 of the aqueous binder is formed on the upper surface of the hot melt layer 33. The adhesive layer 5 and the hot melt layer 33 are melted by the heat-fixing step (S40) by performing the heat-fixing step (S40) at the same time as the formation, and flow into the voids between the glitter powders to ensure the adhesion of the glitter powder. It can be remarkably increased.

The water-based binder adhesive layer forming step (S30) is the water-based binder of FIG. 4 manufactured by the water-based binder manufacturing step (S20) on one side of the hot-melt layer 33 of the hot-melt film 3 prepared by the hot-melt film preparation step (S10). This is a process step of forming the adhesive layer 5 by applying or spraying 20).

In addition, when the glitter powder is simply adhered using only the adhesive binder, the phenomenon that the glitter powder is separated by external shock and vibration occurs, but in the present invention, the aqueous binder 20 is contained through the aqueous binder manufacturing step (S20). The components are mixed in an appropriate amount and at the same time, the adhesive layer 5 of the aqueous binder is formed on the upper surface of the hot melt layer 33, and the adhesive layer 5 by the heat-fixing step (S50) is performed by performing the heat-fixing step (S50). And the hot melt layer 33 is melted and introduced into the voids between the glitter powders, so that the adhesion of the glitter powder can be remarkably improved.

The glitter powder forming step (S40) is a process step of sprinkling the glitter powder 7 on the laminate by the aqueous binder adhesive layer forming step (S30).

At this time, the glitter powder 7 is made of reflective particles such as gold powder, silver powder, aluminum powder, glass beads, hologram powder, a mixture of sequins and transparent binder, and synthetic resin powder having a reflective surface. It has the advantage of realizing a shiny appearance on the surface of an object by reflecting light from it.

That is, the glitter powder 7 sprinkled by the glitter powder forming step (S40) is fixed to one surface of the hot melt layer 33 by an aqueous binder.

The heat-fixing step (S50) is a process step of heat-fixing the glitter powder 7 by heating the laminate obtained by the glitter powder forming step (S40) to a temperature of 100 to 150°C.

At this time, in the heat-fixing step (S50), if the heating temperature is less than 100°C, the temperature is lowered by the overloading agent, so that the adhesion of the glitter powder 7 decreases, and if the heating temperature exceeds 150°C, the aqueous binder is excessively heated. There is a problem of burning.

The printing and transfer step (S60) is a process step of printing a previously produced design and color pattern and printing it on a transfer paper.

In addition, in the printing and transfer step (S60), a conventional ink, in detail, an aqueous ink is applied.

The printing and transfer paper cutting step (S70) is a process step of cutting the print and transfer paper on which the pattern is printed by the printing and transfer step (S60) according to the size of the pattern.

The heat press step (S80) is a stack of printing and transfer paper cut by the printing and transfer paper cutting step (S60) on the upper surface of the glitter powder 7 of the laminate fixed by the heat-fixing step (S50). After that, it is a process step of performing heat press using a conventional heat press device.

At this time, the ink printed on the printing and transfer paper is absorbed and adhered to the aqueous binder adhesive layer 5 and the glitter powder 7 by heat press, so that the previously produced pattern is printed and transferred to the glitter powder 7.

The transfer paper peeling step (S90) is a process step of separating the printed and transfer paper from the laminate heat-pressed by the heat pressing step (S80), and then cutting the separated laminate to a preset size.

As described above, in the manufacturing method (S1) of the glitter film, printing, and transfer, which is an embodiment of the present invention, the adhesiveness of the glitter powder can be remarkably improved by forming a water-based adhesive binder on one surface of the hot melt layer and performing a heat-fixing process. do.

In addition, the manufacturing method (S1) of the glitter film and printing and transfer of the present invention is not only harmless to the human body compared to the case of applying the conventional oil-based binder by applying a water-based binder for the purpose of enhancing the adhesion of the glitter powder. Water absorption and adhesion can be improved, and smoothness, flexibility and elasticity of the glitter particles are improved, so that the surface feel can be remarkably improved.

In Examples 1 to 6, it can be seen that 1) the adhesiveness test of Experimental Example 1 was measured as 96 or more, as the content of the first additive of the aqueous binder was contained in an appropriate content of 11.0 to 19.0% by weight. 2) As the content of acrylic acid in the aqueous binder is contained in an appropriate content of 0.1 to 2.0% by weight, the sharpness test of Experimental Example 2 was evaluated as an image, indicating that the sharpness was excellent, and 3) butyl acrylic acid in the aqueous binder- As the content of the 2-hydroxyethyl acrylic acid-methyl acrylic acid copolymer was contained in an appropriate content of 10.0 to 15.0% by weight, it can be seen that all of the light fastness tests of Experimental Example 3 were measured at 94 or more excellently.

On the other hand, Comparative Example 1 showed that the first additive of the aqueous binder contained 9.0% by weight, which is less than the proper content of 11.0 to 19.0% by weight, so that the adhesiveness test was measured to be 84, and the adhesiveness was poor compared to the Examples It can be seen, and in Comparative Example 2, as the first additive of the aqueous binder was added 21.0% by weight, which is greater than the proper content of 11.0 to 19.0% by weight, it can be seen that the adhesiveness was poorly deteriorated. At this time, although not described in this experimental example, it can be visually confirmed that cracks occur when the content of the first additive exceeds 19.0% by weight.

In Comparative Example 3, as the acrylic acid of the aqueous binder contained 0.03% by weight, which is less than the appropriate content of 0.1 to 2.0% by weight, the clarity test and the light fastness test were measured as'medium' and '89'. And it can be seen that the light fastness is lowered.

In Comparative Example 4, as the acrylic acid of the aqueous binder contained 4.0% by weight, which is greater than the appropriate content of 0.1 to 2.0% by weight, the clarity test and the light fastness test were measured as'top' and '81'. Is good, but it can be seen that the light fastness is remarkably poor.

Comparative Example 5 contained 7.0 wt%, which is less than 10.0 to 15.0 wt% of the aqueous binder's butyl acrylic acid-2-hydroxyethyl acrylic acid-methyl acrylic acid copolymer, so that the adhesion test and the light fastness test were '86' and '85. It can be seen that the adhesiveness and light fastness are lowered compared to the examples by measuring the number of dogs.

Comparative Example 6 contained 18.0% by weight greater than 10.0 to 15.0% by weight of the butyl acrylic acid-2-hydroxyethyl acrylic acid-methyl acrylic acid copolymer of the aqueous binder, so that the adhesion test and the light fastness test were '94' and '86. It can be seen that the adhesiveness was excellently measured as 94 as compared to the examples, but the light fastness was remarkably inferior.
