Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer print containing a fragrance, and more particularly to a transfer print containing a fragrance having a beautiful finish and having a characteristic that the fragrance of the fragrance lasts for a long time.

[0002]

2. Description of the Related Art A conventional printed matter for transfer is disclosed in Japanese Patent Laid-Open No. 63-63.
The one shown in −264390 is known.
In the above-mentioned transfer print, a transparent overcoat layer is formed on one surface of the base film, an ink layer of multiple colors is formed on the upper surface of the transparent overcoat layer, and an adhesive layer is sequentially formed on the upper surface of the ink layer. It was done.

By the way, the above-mentioned transfer printed matter is not configured to emit a fragrance, but it is also known that a fragrance is blended with the transfer printed matter for the purpose of releasing the fragrance.

[0004]

The conventional fragrance-transferring printed matter is one in which the ink stock solution of the fragrance is enclosed in microcapsules and made into an ink form with an aqueous binder or the like as the outermost surface of the product. Blended only in the transparent overcoat layer located on the side, and after printing and drying this transfer print, rub the surface of the product with a nail etc. to break the microcapsules contained in the transparent overcoat layer and diffuse the aroma to the vicinity. It was being done.

In addition, it is also possible to mix the perfume undiluted solution in the transparent overcoat layer located on the outermost surface side without encapsulating the perfume in microcapsules, but the perfume in the transparent overcoat layer is a volatile organic substance. As it is a type of solvent, it is always volatilized.
Even if it is slow, the aroma disappears in about 15 days, and there is a problem that the feature of aroma emission disappears by the time the product reaches the market.

In addition to this, since the thickness of the ink layer of the microencapsulated perfume is at least about 20 μm, when the products are stacked and stored after printing, the microcapsule parts bulge to a bulky state, and There was also an adverse effect that the microcapsules were easily damaged.

Furthermore, since the fragrance of the perfume in the transparent overcoat layer is always volatilized even after printing and drying the transfer print, the surface of the products stored in the stack is softened by the effect of the organic solvent, There was also a problem that overlapping products would adhere to each other.

The inventor of the present invention doubts that the conventional ones have added the fragrance only to the transparent overcoat layer located on the outermost surface, and has a plurality of ink layers and has elasticity and ultrathin film property. In a transfer print product that also has a transparent overcoat layer that also has a double layer, by adding an appropriate amount of fragrance to each ink layer, it is possible to prevent unnecessary emission of the fragrance of the fragrance and maintain the fragrance before use. The purpose of the present invention is to provide a product that solves all the above problems.

[0009]

The present invention provides 25-200.
A transparent overcoat layer having a thickness of 5 to 30 μm and having the same shape as the seal pattern is formed on one surface of a transparent or semitransparent base film having a thickness of μm by a printing means. Ink having the property of being able to expand and contract following the expansion and contraction, and having a release agent and a curing agent added, and an ink having a thickness of 5 to 10 μm by a printing means on the upper surface of this transparent overcoat layer. A plurality of layers are formed, and 5-1 is formed on the entire upper surface of this ink layer.
In a printed matter for transfer formed by forming a 0-micron-thick adhesive layer, the overcoat layer contains 10 parts by weight of a resin material, 1 to 3 parts by weight of a fragrance, 1 part by weight of a curing agent, and 0.5 parts of a release agent. Formed in parts by weight, the perfume is not mixed in the pressure-sensitive adhesive layer and the immediate ink layer adjacent to the pressure-sensitive adhesive layer, and ink is added to each ink layer except for the immediate ink layer adjacent to the pressure-sensitive adhesive layer. A transfer print containing a fragrance, characterized in that 0.5 to 1.5 parts by weight of a fragrance is mixed with 10 parts by weight and 1 part by weight of a curing agent is mixed in the nearest ink layer.

[0010]

According to the present invention, since each ink layer is also mixed with a fragrance as a printed matter for transfer, the fragrance in this ink layer gradually exudes to the transparent overcoat layer on the upper surface to give a proper fragrance for a long time. You can now diverge. Further, since the fragrance is not intensively mixed in the transparent overcoat layer, the transparent overcoat layer is not unnecessarily softened.

On the other hand, in the present invention, since the fragrance is not mixed in the adhesive material layer and the immediate ink layer, the adhesive strength of the adhesive material layer is not hindered by the organic solvent of the fragrance, and the adhesive strength can be maintained safely. Become.

EXAMPLES The present invention will be specifically described below with reference to examples, but the present invention is not limited thereto. First
FIG. 2 and FIG. 2 are vertical cross-sectional views of the transfer print of the present invention. In the figure, reference numeral 1 is a base film made of a material such as polyethylene or polypropylene and has a thickness of 25 to 200 μm, and reference numeral 2 is a transparent overcoat layer having a thickness of 5 to 5 μm.
8 micron, and further reference numerals 3a, 3b, 3c, 3d
Is an ink layer having a thickness of 5 to 10 microns, and 4 is an adhesive layer having a thickness of 5 to 10 microns.

Example 1 The transparent printed material for transfer shown in FIG.
10 parts by weight of resin material, 2 parts by weight of fragrance, 1 part of curing agent
It was formed by blending 0.5 parts by weight of a release agent and 0.5 parts by weight. In the first ink layer 3a, 10 parts by weight of black ink and 1 part by weight of fragrance were mixed. In the second ink layer 3b, 1 part by weight of the fragrance was mixed with 10 parts by weight of the red ink. In the third ink layer 3c, 1 part by weight of the fragrance was mixed with 10 parts by weight of the yellow ink. 4th ink layer 3d
(Here, since the ink layer consists of four layers in all, this becomes the nearest ink layer) was constituted by adding 10 parts by weight of a white ink and 1 part by weight of a curing agent, and no perfume was added thereto.

The above-mentioned printed matter for transfer was transferred onto the chest of a shirt and the shirt was worn. As a result, the initial fragrance emitted from the product was a moderate fragrance without being too strong, and the fragrance gradually decreased after 30 days, but the fragrance can be fully enjoyed even after 60 days. did it. The transparent overcoat layer 2 did not become particularly soft after 60 days, and the adhesive strength of the adhesive layer 4 did not decrease at all.

Comparative Example 1 A transparent overcoat layer similar to that of Example 1 above and first to fourth ink layers similar to Example 1 except that no perfume was added were prepared.

As a result, the aroma initially emitted from the product was quite weak, and the aroma could not be felt unless the nose was brought close to it, and after 4 days, the aroma could hardly be felt.

In order to solve the problem, the experiment of Comparative Example 2 was carried out by adding only 1 to 5 parts by weight of the blending amount of the fragrance in Comparative Example 1.

As a result, when only 1 part by weight of the fragrance was added, the fragrance initially emitted from the product was a moderate fragrance, but after 7 days, the fragrance could hardly be sensed.

When 2 parts by weight of the fragrance was added, the initial fragrance emitted from the product was a slightly strong scent.
After 15 days, I could hardly feel the scent.

If 5 parts by weight of fragrance is added,
The original fragrance emitted from the product was too strong and made me feel uncomfortable, but after about 5 days, it became a moderate fragrance.
After 0 days, I could hardly feel the scent. Further, in this case, bubbles were generated in the transparent overcoat layer to soften it, and the sticky feeling was so strong that it became unusable.

Next, 1 part by weight of the fragrance was compounded also in the fourth ink layer (nearest ink layer) 3d of Example 1, and no curing agent was compounded in the fourth ink layer 3d (all other conditions were used. The same as in Example 1) was prepared and the experiment of Comparative Example 3 was performed.

As a result, after 15 days, the perfume penetrated from the fourth ink layer 3d, and the adhesive force of the pressure-sensitive adhesive layer 4 was deteriorated by the action of the volatile organic solvent.

From the above-mentioned various experiments, blending the fragrance only in the transparent overcoat layer has a problem that the fragrance is emitted in a short time even if the blending amount is increased, and thus it cannot be used as a product. When a UV-curable transparent overcoat layer is used, there is a problem that solvent resistance is too strong to prevent permeation of perfume from the ink layer. In addition, when a transparent overcoat layer of the same material as in the example is used, However, it was found that if the thickness exceeds 30 microns, there is also a problem of impeding permeability.

In particular, if the amount of the fragrance compounded in the transparent overcoat layer 2 is less than 1 part by weight with respect to 10 parts by weight of the resin material, the fragrance of the fragrance is insufficient, and if it exceeds 3 parts by weight, the transparent overcoat layer is deficient. In addition to being easily softened by the adverse effect of the fragrance, the fragrance of the product is too strong, which causes discomfort.

Further, if the amount of the fragrance compounded in each of the ink layers 3a to 3c is less than 0.5 parts by weight relative to 10 parts by weight of the ink, the fragrance of the fragrance is insufficient, and if it exceeds 1.5 parts by weight. It is not practical because there is a problem that it takes a lot of time to dry when printing an ink layer and then printing the next ink layer again.

It has also been found that when a fragrance is blended in the immediate ink layer, the fragrance permeates the pressure-sensitive adhesive layer, and the influence of the fragrance deteriorates the pressure-sensitive adhesive strength of the pressure-sensitive adhesive layer. In the present invention, in order to prevent the perfume contained in the previous ink layer from penetrating into the pressure-sensitive adhesive layer in the nearest ink layer, the curing agent is preferably added in an amount of about 1 part by weight to improve the effect. .

[0027]

As described above, according to the present invention, by devising the shape and design of the transfer print, it is possible to add a fragrance that is suitable for the product, and to give the product a sense of presence and dynamism. The commercial value of the product can be increased.

At that time, there is an effect that the aroma emitted from the product can be retained for an extremely long time, a sticky feeling on the product surface can be prevented, and further deterioration of the adhesive force of the adhesive layer can be prevented. It also has excellent features.
