[Object of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic transfer product obtained by subjecting a semi-finished product made of, for example, a plastic material, a metal material, a ceramic material or the like to a special surface treatment.

[0002]

BACKGROUND OF THE INVENTION One of the methods for printing on a curved surface is so-called hydraulic transfer printing. In this printing method, an activator is applied to the water-soluble thin film on which the transfer pattern is printed to activate the ink in the transfer pattern, and while this is floated on the water surface, the transfer target is pressed against the water-soluble thin film. , The transfer pattern is transferred to the transfer target by water pressure,
For example, when applying a color difference between the transferred part of the pattern and the part where the background color of the transfer target is not transferred or is printed, or when applying a pattern printed with two or more colors of ink,
Various patterns can be drawn by the difference between the colors formed by the overlap with the background color of the transferred material. However, although this method can draw various patterns, the texture has a certain limit because it cannot exceed the texture of the ink of the pattern.

On the other hand, in today's natural-oriented boom,
Although wood-like products are becoming more popular, wood is expensive and difficult to process. Therefore, it has been attempted to print, for example, a wood grain pattern of a name tree by hydraulic transfer printing, but it is inferior in terms of depth feeling and shiny feeling compared to a product obtained by processing wood.

[0004]

[Technical Items Attempted to Develop] The present invention has been made in view of such a background, and an attempt has been made to develop a hydraulic transfer printing method that can be made closer to the texture of a material such as wood. Is.

It is characterized in that it has a second transfer layer composed of a woodgrain pattern on the top, and that the pearlescent pigment is dispersed in the second transfer layer.

A second aspect of the present invention, which is a method for printing a hydraulic transfer printed product, is a method for printing a water-soluble thin film on which a transfer pattern is printed with ink, which is floated on the water surface in the active state of the ink. Press the transfer target from above to immerse part or all of the transfer target below the surface of the water, transfer the transfer pattern to the transfer target by hydraulic pressure, remove the water-soluble thin film with water, and dry to top coat When the transfer pattern is printed on the transfer target by performing the above step, any one or more of the ink, the activator of the ink, and the paint of the top coat contains a pearlescent pigment.

Furthermore, in addition to the above-mentioned requirements, the third aspect of the present invention provides a method for printing a hydraulic transfer printing product, wherein a water-soluble thin film obtained by printing the first transfer pattern with an ink is applied to the water surface in the active state of the ink. Float on top, press the transfer target from above this water-soluble thin film to immerse part or all of the transfer target below the water surface, and transfer the first transfer pattern to the transfer target by water pressure and After removing the thin film with water, it is dried to form the first transfer layer, then the water-soluble thin film on which the second transfer pattern is printed with ink is floated on the water surface in the active state of the ink, The transfer target on which the first transfer layer is formed is pressed from above the thin film to immerse part or all of the transfer target below the water surface, and the second transfer pattern is moved to the first transfer target of the transfer target by hydraulic pressure. Water-soluble thin film as well as transfer to one transfer layer After removing with water, it is dried to form a second transfer layer, and further topcoat is performed. In the process of forming the second transfer layer, the transfer pattern ink, the activator of this ink or the topcoat paint is used. Any one or two or more of pearlescent pigments are included.

Furthermore, in addition to the above-mentioned requirements, in the method of printing a hydraulic transfer printed product according to a fourth invention of the present application, the second transfer pattern is printed with ink in the process of forming the second transfer layer.

Further, if the pearlescent pigment is dispersed in the second transfer layer by performing the hydraulic transfer twice on the transferred material, the pearlescent pigment can be applied to the ink or the base material of the first transfer pattern. By interacting with the colors, a unique color, depth, and shiny feeling can be created, giving a texture close to that of natural materials.

Further, if the ink of the first transfer pattern is a dark color system, the pearlescent pigment is remarkably colored, and if the first transfer pattern is dot-shaped, the pearl luster on the dots is increased. Since the pigment and the pearlescent pigment that are not on the dots have different coloring states, it is possible to create a more unique texture by the stepwise coloring of both.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to illustrated embodiments. First, a hydraulic transfer line 1 for performing hydraulic transfer will be described in connection with the present invention. As shown in FIG. 1, the hydraulic transfer line 1 includes a hydraulic transfer device 2, a supply conveyor 3, a connection conveyor 4, a discharge conveyor 5, and a connection conveyor 4 which are continuously arranged on the side thereof. It is provided with an automatic supply device 6 and an automatic discharge device 7 which are provided on the side of the hydraulic transfer device 2.

The hydraulic transfer device 2 includes a transfer tank 10 for containing water W, a transfer conveyer 11 above which a transfer target holding device 14 is provided at regular intervals, and a print film supply device 12. It consists of. Printing film supply device 1
Reference numeral 2 denotes an original roll 15 in which a pattern printing film F which is a water-soluble thin film is wound in a roll shape, and a solvent tank 16 which stores an activator S for activating the ink printed on the pattern printing film F. It is made up of
The pattern printing film F fed from No. 5 is activated by the activator S in the solvent tank 16 on the way and then transferred to the transfer tank 1.
A feed roller 17 is provided as appropriate so that it can be continuously fed into 0. Further, the automatic supply device 6 is provided with a plurality of gripping devices 18, and the gripping device 18 chucks a transfer target material to supply the transfer target material from above into the transfer tank 10 and to discharge the transfer material after the transfer is completed. .

Although hydraulic transfer printing is carried out using such a hydraulic transfer line 1, the present invention is characterized in that the hydraulic transfer is performed twice on the transferred material. Hereinafter, the process of hydraulically transferring a woodgrain pattern to an automobile operation panel 20 as a transfer target will be described. First, from the printing film supply device 12, the pattern printing film F _{1 which} is a water-soluble thin film on which the black dot pattern P _{1 which} is the first transfer pattern is printed is supplied onto the water surface in the transfer tank 10. Here, the pattern printing film F ₁ is obtained by printing a fine dot pattern P ₁ on a water-soluble film F ₀ such as gelatin, sodium alginate, or polyvinyl alcohol as shown in FIG.

Further, since the pattern printing film F ₁ is usually stored as an original roll, the coating film needs to be in a dry state. Therefore, when the pattern printing film F ₁ is used, it is not supplied into the transfer tank 10. Then, as shown in FIG. 3, the activator S ₁ in the solvent tank 16 is made to act to give tackiness. The pattern printing film F ₁ may be coated with the activator after the pattern printing film F ₁ is supplied onto the water surface. Further, as the activator, a resin such as a resin component, a pigment, a solvent, a plasticizer and the like are mixed, and a solvent such as thinner can be simply used.

The pattern printing film F ₁ thus coated with the activator S ₁ absorbs water, softens and swells, and spreads in all directions. When the tackiness of the ink and the spreadability of the water-soluble film become appropriate, the operation panel 20 as a transfer target attached to the gripping device 18 is brought close to the water surface from above the water surface, and then the pattern printing film F ₁ is pushed down. To submerge.

As a result, the pattern printing film F ₁ is
The dot pattern P ₁ is transferred to the operation panel 20 by being closely adhered to the operation panel 20 along the irregularities of the operation panel 20 by water pressure and covering the operation panel 20 with a film. At this time, the water-soluble film F ₀ is partially dissolved in the water W, but after the operation panel 20 reaches the rising portion 13 of the transfer conveyor 11 and is discharged, a shower ring or a shower ring is used to completely remove the water-soluble film F _0. Wash with water. After that, the operation panel 20 is dried in the drying step, and the first transfer layer L ₁ is formed on the surface of the operation panel 20. The first transfer layer L ₁ serves as a base of the second transfer layer L ₂ which will be formed later.
₁ can also be applied with a clear coat similar to the top coat. By the way, when a clear coat is formed on the first transfer layer L ₁ , the clear coat can increase the feeling of shinyness and depth and can produce a high-grade texture.

Next, the formation of the second transfer layer L ₂ will be described. As shown in FIG. 4, a pattern printing film F ₂ which is a water-soluble thin film in which a wood-grain pattern P ₂ which is a second transfer pattern is printed with ink is prepared, and as an example, it contains a pearlescent pigment G showing a golden color. It is activated with the activator S ₂ and floated on the water surface. By the way, the activator S ₂
By including the pearlescent pigment G in the
Are present in the second transfer layer L ₂ , and can interfere with the colors of the ink and the base material to produce unique color development, depth feeling, and shiny feeling.

Now, the pearlescent pigment applied to the present invention will be described. This is a pigment that has an elegant luster called perlescence due to multiple reflections of light. Although natural pearlescent pigments that have been used for a long time are collected from fish scales, many synthetic products are made because natural products are difficult to mass produce and expensive.

The pearlescent pigment is composed of a transparent substance having a high refractive index, and the particles are flaky, and it is necessary that the flakes are arranged in layers when colored. The size of the flakes is 5-150μ
A wide m and a small one (5 to 30 μm) have a soft luster similar to silk, and a large one has a glittering metallic luster.

Natural pearlescent pigments are fine crystals of guanine, while synthetic pearlescent pigments are basic lead carbonate [PbCO ₃ ·.
Pb (OH) ₂ ], lead hydrogen arsenate (PbHAsO ₄ ), bismuth acid chloride (BiOCl) and other substances, as well as titanium mica has been developed in recent years and is superior in terms of robustness and safety. It is widely used because This mica titanium can be obtained by peeling mica into thin pieces along the cleavage plane and coating the thin pieces with titanium dioxide having a high refractive index. The amount of titanium dioxide to be coated is 20 to 50%, a small amount exhibits a white pearl luster, and a large amount exhibits an iris color due to interference. Further, depending on the thickness of the flakes, the iris color or the interference color colored by the interference of the reflected light is exhibited. As described above, the pearlescent pigment exhibiting an iris color is the most suitable for the present invention, and this pigment has a property that the deeper the background color is, the stronger the coloring is. Here, the dark color includes dark colors such as black, dark brown, and indigo, as well as red, blue, and the like, as long as they are dark. Commercially available iris-colored pearlescent pigments include Irio of Merck Japan Co., Ltd.
din (registered trademark) 205, 215, 217, 219, 225, 23
5 and Hi-lite of Marl Corporation
Gold, etc. As another pearlescent pigment, there is also a colored type in which a titanium dioxide layer is coated with iron oxide, which exhibits a golden or bronze pearlescent luster.

Next, in a state in which the pattern printing film F ₂ is floated on the water surface, the operation panel 20 having the first transfer layer L ₁ formed thereon is pressed from above the pattern printing film F _{2 so} that it is below the water surface. And the woodgrain pattern P ₂ is transferred by being superposed on the black dot pattern P ₁ by water pressure. After that, the pattern printing film F ₂ is removed with water, and after drying, a top coat is applied, and after drying and evaporation of the solvent, buffing is performed if necessary, whereby the operation panel 20 having a wood pattern is completed.

Incidentally, in the operation panel 20 printed in this way, the pearlescent pigment G adheres to the entire printing surface as shown in FIG. 5, but the pearlescent pigment exhibiting an iris color has a dark background. If so, the more intense the coloring is, the portion where the woodgrain pattern P ₂ is not printed and where there is a black dot where the pearlescent pigment G can be colored most as a background interferes with the black dot. It produces a deep color and a unique feeling of depth and shine. Also, wood grain pattern P
_If the base color of the transferred material is dark, the pearlescent pigment G interferes with the base color even if there is no black dot in 2 Correspondingly, the color develops to a lesser degree than black, and a certain depth and shiny feeling are produced. As a result, the pearlescent pigment G develops its color stepwise according to the base, and a texture resembling the wood tone of a name tree with a feeling of depth and a feeling of light can be produced, and the black dot portion that is the first transfer pattern is generated. However, the texture of the wood is improved by appearing to form a tree.

In FIG. 5, the activators S ₁ and S ₂ are shown as independent layers separately from the ink for convenience of description.
In fact, when the ink is in the active state, both the ink and the active agent exist in a mixed state, and when the hydraulic transfer is completed, the solvent of the active agent evaporates by drying, and the residual components of the active agent and the ink or pearl are It will be mixed with a luster pigment.

In the above embodiment, in order to give a wood texture,
The first transfer pattern was a black dot shape and the second transfer pattern was a wood grain pattern, but even if the same wood texture is produced, the first transfer pattern can be a solid paint pattern or another form of transfer pattern can be applied. You can also do it. In addition to the wood texture, various textures such as marble, granite, and opal can be expressed by appropriately combining the first transfer pattern and the second transfer pattern.

Although the pearlescent pigment G is contained in the activator S ₂ in the above-mentioned examples, in addition to this, the ink for printing the second transfer pattern, the top coat paint, or the first transfer layer is used. A pearlescent pigment may be mixed in the clear coat paint to be applied. In this case, the layer below the layer in which the pearlescent pigment is mixed has a dark color such as black,
It is necessary to fully bring out the above functions of the pearlescent pigment.

Although the above is an embodiment in which the hydraulic transfer is performed twice, the present invention can be applied to a single hydraulic transfer printing. That is, in the same manner as the step of forming the first transfer layer, the activator acts on the water-soluble thin film on which the transfer pattern is printed by the ink to give tackiness to the ink, and in this state, the transfer tank 10
Supply above the water surface. Then, the transfer target attached to the gripping device 18 is made to approach the water surface from above the water surface, and then the water-soluble thin film is submerged so as to be pushed down to transfer the transfer pattern to the transfer target. After the transfer, the water-soluble thin film is completely removed with water, dried in the drying step, and then top-coated. In the present invention, even in such a single hydraulic transfer, the pearlescent pigment can be contained in one or more of the printing ink of the transfer pattern, the activator of this ink and the top coat paint. .

In this way, the pearlescent pigment adheres to the entire surface of the printing surface, but since there is no underlying printing, the pearlescent pigment is colored in relation to the color of the base material of the transferred material. Become. Therefore, if the base material of the transferred material is, for example, variously color-coded, the pearlescent pigment develops well in the dark part, especially in the black part, and not so much in the other parts. The color is developed, and a certain depth and shiny feeling are produced in the color-developed portion.

[0033]

INDUSTRIAL APPLICABILITY In the present invention, the second transfer layer is provided on the first transfer layer in an overlapping manner, and the ink of the transfer pattern of the second transfer layer, the activator of this ink or the top coat paint is used. Since one or more pearlescent pigments are contained in the pearlescent pigment, the pearlescent pigment interferes with the ink of the first transfer layer and the color of the base material to form a color, and the pearlescent pigment gives a feeling of depth and shine. The texture of the transfer pattern of the second transfer layer can be improved.

If the first transfer pattern is a black dot pattern and a wood grain pattern activated by an activator containing a pearlescent pigment is superposed thereon and hydraulically transferred, the pearlescent pigment is coated with a base material. The color gradually develops to create a texture that is very similar to the tone of wood with a sense of depth and a feeling of light, and the black dots appear to make up the wood and improve the wood texture. .

Further, even when the hydraulic transfer is performed once, if a pearlescent pigment is contained in one or more of the printing ink for the transfer pattern, the activator of this ink, and the top coat paint, The pearlescent pigment develops a color in relation to the color, and it is possible to obtain a feeling of depth and shine on the printed surface.
