Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a film that can easily transfer a pattern drawn on the surface of chewing gum when pressed against it, and an ink used therein.

Problems to be Solved by the Present Invention In general, chewing gum with no pattern is predominant in the market in the form of a plate, and only occasionally is one with an engraved pattern. The present invention overcomes the current state of chewing gum and adds a new hobby to it by making it possible to apply pressure and transfer pictures onto the surface of chewing gum in the style of a painting.

Solution to the Problem In the present invention, a specific ink is used.
The materials used for the ink will be explained below.

A water-soluble colorant such as caramel, beetroot, spirulina colorant, etc. is used as the colorant. Although oil-soluble inks cannot be used at all, they seem to have some drawbacks, such as the adhesion of the ink to the film and the dyeing properties after transfer.

The water-insoluble powder substance is a water-insoluble powder capable of adsorbing or absorbing and retaining pigments, such as various starches and calcium carbonate powder.
Although it cannot be absolutely specified because it varies depending on the type of pigment, the type of powder material, particle size, etc., approximately 0.5 to 2 parts are used for 1 part of pigment.

The solvent is a solvent for the dye, such as alcohol, water, etc. the dye is adsorbed to the powder material;
In addition to making it easier to absorb, it is also used to maintain the appropriate fluidity of the prepared ink.

The humectant is a moisture-absorbing or moisturizing agent, such as propylene glycol, sorbitol, reduced starch hydrolyzate, and glycerin. It is used to prevent or control the drying of the prepared ink, and although it cannot be absolutely defined depending on the type of pigment or wetting agent, it is approximately 0.1 to 1.0 per pigment 1. Enough.

The binder is used to bind the mixture of the above-mentioned four types of materials or to adjust the viscosity of the ink, and either oil-based or water-based is selected depending on the situation. Among these, oil-based ones include edible oils and fats, and water-based ones include starch syrup, reduced starch hydrolyzate, and the like. The amount used may be approximately 0.1 to 0.5 based on the pigment.

The ink of the first invention (the inventions recited in claims 1 and 2 are referred to as the first invention and the second invention, respectively; the same shall apply hereinafter) is obtained by mixing and kneading the above-mentioned respective elements in the above-mentioned quantitative ratios. be.

The silicone release paper used in the second invention is no different from ordinary silicone release paper. For example, silicone is coated on paper at about 0.1 to 5 g/m ² .
The transfer film of the second invention is obtained by printing the ink of the invention on a silicone release paper by, for example, a screen printing method. This film may be covered with a cover film having low moisture permeability to prevent drying or moisture.

Functions and Effects In order for ink to be able to be printed or transferred from a film, ○a) the ink must have a certain degree of adhesiveness to the film, ○b) the ink must not be absorbed into the film, that is, it must not seep into the inside of the film. What not to do, ○ha When applying pressure,
It is required that the transfer and adhesion from the film to the chewing gum be easy and reliable. However, it is very difficult to satisfy all of these requirements at the same time. In the present invention in which a water-soluble dye is coated on a silicone release paper in order to satisfy the above requirements ○B and ○C, satisfying the above requirements ○B becomes a major issue. In particular, when the ink dries, it tends to peel off from the film even more frequently. The two inventions of the present application, which were constructed with these considerations in mind, have the following functions and effects.

(b) The ink has good spreadability and can be easily printed on not only chewing gum but also film. The ink, which is bound together by a binder, contains a powder substance and is plastic as a whole, so it has malleability and shape retention, making it suitable for printing.

(b) The pigment is uniformly dispersed or diluted. Since it is diluted with a solvent and adsorbed onto the powder material, it does not cause mottled coloration.

C. The adhesion of ink to silicone release paper is improved. This is probably because the entire product is viscous due to the binder and has appropriate hardness, and at the same time, drying is appropriately suppressed by the addition of a wetting agent.

In addition, when transferring with the film of the second invention, although it cannot be absolutely specified depending on the type of material of the chewing gum or the blending ratio, it seems that the water content of the chewing gum should be about 2 to 4%. . Furthermore, when transferring, it seems that wiping away free water or moisture from the surface of the chewing gum will improve the finish of the transfer.

Example 1: Beetroot 30% (weight, same below), cornstarch 20%, calcium carbonate 20%, water 20%,
A red ink consisting of 1% glycerin fatty acid monoester, 6% propylene glycol, and 3% cacao butter was prepared. When this product was screen-printed on the surface of chewing gum (2.5% moisture) prepared by a conventional method, it had good adhesion and a beautiful printed pattern could be obtained.

Part 2: The ink prepared in Part 1 above was printed on silicone release paper by screen printing. Cellophane was layered on the resulting film and stored at room temperature for one week, and then the cellophane was peeled off, but the drawn pattern layer was adhered to the silicone release paper and did not peel off. This is mixed into bubble gum (moisture content) prepared according to a conventional method.
3.5%), the pattern layer was easily transferred and fixed to the gum, resulting in a gum with a beautiful pattern.

Claims (1)

[Scope of Claims] 1.
