Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in a strong and durable baked-on transfer mark.

[Conventional technology]

Conventional printing-type transfer marks are made by forming a printing ink layer on a mount having a water-soluble adhesive layer on the surface, using a thermosetting resin, such as a liquid epoxy resin, as a medium and mixing color pigments with it. A plastic film-like cover coat layer mixed with silicone resin or the like, which can be peeled off after heat treatment, is laminated on the ink layer. After dipping in a water-containing solvent to semi-dissolve the water-soluble glue layer and separating the backing paper, the printing ink layer is pressed onto the transfer target and heated at a temperature of about 60° to 100°C, after the printing ink layer has hardened. The process of peeling off the uppermost cover coat layer, spraying the printing ink layer with a clear lacquer made of a diluted liquid epoxy resin, and re-baking to fix the printing ink layer was essential. This re-baking process is generally called a clear coating process, but if this process is omitted, the cured printing ink layer will be directly exposed to the air, which will accelerate the deterioration of the layer, or It is not suitable as it has drawbacks such as being susceptible to injury.
A clear application process that would increase the durability of the layer without detracting from its appearance was desperately needed.

However, adding a clear coating process that requires baking again after the cover coat has been removed increases the number of steps and is cumbersome, and furthermore, there is a risk of manufacturing defects occurring during this process. When considering losses etc., improve this and
There was a strong demand for measures to create more efficient and superior transfer marks.

[Problem that the invention attempts to solve]

The present invention was developed in view of the above-mentioned circumstances, and it eliminates the above-mentioned clear coating process, greatly improves work efficiency, eliminates defective products that occur during the clear coating process, and furthermore allows re-baking. The object of the present invention is to provide a burn-on type transfer mark that can eliminate drying and greatly reduce transfer costs.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention aims to: a. Form a printing ink layer on a mount having a water-soluble glue layer on the surface by using a thermosetting resin as a medium and mixing color pigments therein; In a baking-type transfer mark formed by laminating a cover coat layer that can be peeled off after heat treatment, b) a layer containing only a medium that does not contain the color pigment is provided between the printing ink layer and the cover coat layer; (c) The gist is a transfer mark formed by intervening, and in addition, as an embodiment thereof, in order to further improve the adhesion ability to the transferred object, (d) the water-soluble glue layer and the printing ink layer are interposed. A transfer mark is presented in which a layer of only a medium that does not contain the color pigment is interposed between them.

The present invention will be described below based on embodiments with reference to the drawings.

〔Example〕

FIGS. 3 and 4 are cross-sectional explanatory views showing the state of formation of conventional burn-on transfer marks.

A water-soluble adhesive layer 3 is provided on the upper surface of the mount 31 shown in FIG.
2 is provided, and furthermore, a monochrome or multicolor printing ink layer 33 is formed on the upper surface thereof. The ink layer 33 is based on a thermosetting resin, that is, as a medium, and contains a colored pigment mixed therein.

In the conventional printing type transfer mark, the upper surface of the printing ink layer 33 is coated with a cover coat layer 34 made of silicone resin or the like. This coat layer 34 could be peeled off from the printing ink layer 33 after it was heated and solidified. FIG. 4 shows a state in which clear coating A is applied to the printing ink layer 33 transferred to the optical transfer body B from the direction of the arrow.

On the other hand, FIG. 1 is a sectional view showing a burn-on type transfer mark according to the present invention.

Regarding the mount 11, water-soluble glue layer 12, monochrome or multicolor printing ink layer 13, and cover coat 15,
Although it is similar to the conventional transfer mark (see Fig. 3), the feature of the present invention is that a layer containing only a medium containing no color pigment is provided between the upper surface of the printing ink layer 13 and the lower surface of the cover coat 15. 14 to intervene.

This layer 14 can be laminated on the printing ink layer 13 by a printing process following printing of the printing ink layer 13 on the mount 11 .

The thermosetting resin according to the present invention has an angle of 60° to 150°.
Epoxy-based, melamine-based, and other materials that harden preferably at temperatures below 100°C are used in combination or alone. As the solvent, ethanol, butyl cellulose, etc. may be used alone or in combination, and a mixture thereof with water may also be used. Other organic solvents that evaporate at relatively low temperatures are preferably used. By applying the medium-only layer 14, a conventional clearing step as indicated by the arrow in FIG. 4 is completely unnecessary. Now, in order to transfer the transfer mark according to the present invention to an object to be transferred, first, when it is immersed in water for 3 to 5 seconds, the water-soluble glue layer 12 on the mount 11 is semi-dissolved, and the printing ink layer 13, The medium-only layer 14 and the cover coat layer 15 are peeled off in the combined state, and when the back side of the printing ink layer 13 is pressed onto a transfer target (not shown), the ink layer 13 is stuck to the transfer target. Then, when the transfer mark is heated to about 60° to 100° C. together with the object to be transferred in that state, the printing ink layer 13 is solidified, and at the same time, the layer 14 consisting only of the medium covering it is also solidified. Then, when the cover coat layer 15 is peeled off, the layer 14 covers the printing ink layer 13, resulting in a clear-coated transfer that has an effect equal to or better than that of a conventional transfer mark that has gone through this type of baking-type clear process. A mark will appear.

Next, FIG. 2 is a sectional view showing one embodiment of the present invention. In the illustrated example, a water-soluble adhesive layer 22 is provided on the top surface of a mount 21, followed by a printing ink layer 24, a medium-only layer 25, and a cover coat layer 26, similar to the one shown in FIG. In addition, a layer 23 containing only a medium and containing no color pigment is interposed between the water-soluble adhesive layer 22 and the printing ink layer 24. In this case, the layer 23 has a remarkable effect as an adhesive on the object to be transferred after separating the mount 21, and the printing ink layer 23 containing the colored pigment
The adhesion ability is greater than that which is directly pressure-bonded to the transferred object.

[Effect of idea]

The present invention is based on the above structure, and a layer containing only a medium containing no color pigment is formed in advance on the top surface of the printing ink layer in which a thermosetting resin is used as a medium and color pigments are mixed in the conventional baking mold. , the solidification of this layer is intended to replace the clear process, and compared to those that go through the clear process, the clear thickness is even and the finish is much better, and the printing ink layer is It completely covers the mark and is transparent, so there is no damage to its appearance at all.Furthermore, the mark has many advantages such as excellent durability, and the number of man-hours associated with pasting is significantly reduced. This is an extremely useful device when applied to burn-on type transfer marks.
