Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink, an ink ribbon, a transfer paper used for forming a pattern on ceramic products such as ceramics, glass, and enamels, and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, painting of ceramic products such as ceramics, glass, and enamels has been mainly performed by a transfer method. The transfer method is performed by applying a transfer paper on which a pattern is formed to the surface of a ceramic product and firing it. The transfer paper used here is generally formed by a screen printing method.

That is, first, a photosensitive polymer is applied to a woven fabric made of stainless steel or the like. Next, the photosensitive polymer is exposed in a state where the light is partially shielded according to the pattern.
Next, the exposed portion is melted or left to expose the texture, and a plate for pattern making is formed. Then, a paste-like ink composed of a ceramic pigment, a glass component, and an organic vehicle is printed on the transfer paper coated with the water-soluble polymer through the texture of the plate. As a result, a pattern is formed on the transfer paper.

[0004]

However, according to the above-mentioned screen printing method, it takes a lot of time and labor to apply and expose the photosensitive polymer. In addition, since an organic solvent is used for printing, the working environment deteriorates. Furthermore, if a large amount of transfer paper with the same pattern is not manufactured at the same time, the profitability will not be met, and it is not suitable for manufacturing various kinds in small quantities.

Therefore, as an alternative to the screen printing method, for example, a method of transferring a pattern onto the surface of a transfer paper by using a transfer recording medium is considered. The transfer recording medium is, for example, lower alcohol, water-soluble polyethylene glycol montanic acid ester, water-insoluble wax,
It is manufactured by applying a mixed liquid in which a color pigment or the like is mixed onto a base material and drying it (Japanese Patent Publication No. 5-60436). This transfer recording medium is for general office equipment and uses an organic pigment or carbon that is easy to handle and has a wide range of color selection.

However, when the transfer recording medium is used as a coloring material for the above-mentioned ceramic products, the organic pigment and carbon are scattered by firing at 500 to 1000 ° C. Therefore,
The transfer recording medium cannot be used as a coloring material for the transfer paper. In view of the above conventional problems, the present invention has
Ink that can be painted on ceramic products and has excellent heat resistance,
The present invention aims to provide an ink ribbon, a transfer paper, and a manufacturing method thereof.

[0007]

The present invention provides an ink ribbon having an ink layer on the surface of a substrate, wherein the ink layer contains at least 70 mol% of methacrylic acid lower alkyl ester.
Methacrylic acid lower alkyl ester polymers containing 2-3
An ink ribbon comprising 0% by weight, 10 to 70% by weight of wax, and 85 to 30% by weight of a coloring material composed of a glass component and an inorganic pigment.

In the present invention, the ink layer comprises a methacrylic acid lower alkyl ester polymer (hereinafter referred to as "ME polymer"), wax, and a coloring material comprising a glass component and an inorganic pigment. The ME polymer is a methacrylic acid lower alkyl ester homopolymer or a copolymer thereof with another vinyl monomer. The methacrylic acid lower alkyl ester has an alkyl group having 1 to 4 carbon atoms.

As the vinyl monomer used for the copolymerization, styrene, methacrylic acid, acrylic acid lower alkyl ester having an alkyl group having 1 to 4 carbon atoms, vinyl acetate or the like is used. The ME polymer is a homopolymer or copolymer containing at least 70 mol% of methacrylic acid lower alkyl ester. If it is less than 70 mol%, there is a problem that the thermal decomposition property of the ME polymer is deteriorated.

ME polymer is an ink layer (100% by weight)
2 to 30% by weight is blended therein. If it is less than 2% by weight, cracks may occur in the ink layer. On the other hand, when it exceeds 30% by weight, the thermal transfer property of the ink layer onto the transfer paper may be deteriorated. Furthermore,
Considering the presence or absence of cracks in the ink layer and the goodness of thermal transferability, the ME polymer is contained in the ink layer in an amount of 2 to 30% by weight.
It is preferably blended. The ME polymer has good compatibility with wax and also has good thermal decomposability.

As the wax, hydrocarbon wax such as paraffin wax and fatty acid ester wax are used. The softening temperature of the wax is preferably in the range of 40 to 100 ° C. When the temperature is lower than 40 ° C, the ink layer tends to have tackiness at room temperature. On the other hand, 100 ° C
If it exceeds, the thermal transfer property of the ink layer may be deteriorated.

The wax is mixed in the ink layer in an amount of 10 to 70% by weight. If it is less than 10% by weight, it is difficult to transfer the ink layer smoothly. On the other hand, 70
If it exceeds the weight%, cracks may occur in the ink layer. Furthermore, for smooth printing and formation of a good ink layer, the wax is added in an amount of 20 to 20% in the total weight of the ink.
It is preferably 60% by weight.

The total acid value of the ME polymer and wax is
It is preferably in the range of 0.5 to 20. In this case, the dispersibility of the coloring material is good, and cracks do not occur in the ink layer. It is considered that this is because the polar group such as a carboxyl group in the ME polymer affects the dispersibility of the coloring material. When the total acid value of the ME polymer and the wax is less than 0.5, the dispersibility of the coloring material may decrease. On the other hand, if the acid value exceeds 20, the thermal decomposition properties of the ME polymer and the wax may deteriorate.

The acid value is the number of milligrams of KOH (potassium hydroxide) necessary to hydrolyze and neutralize the ester bond in 1 g of the ME polymer and wax (sample), and KOH (mg ) / Sample (g).
Further, in order to obtain a better ink layer, the total acid value of the ME polymer and the wax is preferably in the range of 1.0 to 15. Further, in order to obtain the best ink, it is preferable that the total acid value is in the range of 2-10.

The coloring material comprises a glass component and an inorganic pigment. The glass component is for fixing the inorganic pigment to a ceramic product, and for example, oxides of silicon, aluminum, calcium, magnesium, boron, alkali metal, lead, zinc, zirconium and the like are used. As the inorganic pigment, for example, oxides of iron, cobalt, nickel, copper, selenium, titanium, molybdenum, chromium, manganese, etc., noble metal colloids of gold or rhodium, cadmium selenium, etc. can be used.

The coloring material is 100% by weight of the coloring material.
15-85% by weight of glass component and 85-85% of inorganic pigment
15% by weight is preferable. If the glass component is less than 15% by weight, or the inorganic pigment is 85% by weight
If it exceeds, the adhesion of the ink layer to the ceramic product may be insufficient. On the other hand, if the glass component exceeds 85% by weight, or if the inorganic pigment is less than 15% by weight, the coloring of the ink layer may become light.

The coloring material contains 85 to 3 in the ink layer.
It is blended with 0% by weight. If it exceeds 85% by weight, cracks may occur in the ink layer. On the other hand, 3
When the content is less than 0% by weight, the ink layer can be formed, but when the ink layer is transferred as a pattern onto the surface of a ceramic product and baked, the coloration of the pattern may be insufficient. Further, the blending amount of the above coloring material is 7 in the ink layer.
It is preferably from 0 to 40% by weight. In this case,
A good ink layer can be formed, and the color development of the pattern is also improved.

A plasticizer may be added to and mixed with the ink layer in order to change the thermal properties of the ME polymer. Examples of the plasticizer include phthalic acid plasticizers such as dioctyl phthalate and aliphatic dibasic acid plasticizers such as dioctyl adipate.

In order to improve the dispersibility of the coloring material composed of the glass component and the inorganic pigment in the ink layer,
It is preferable that a dispersant is mixed. Examples of the dispersant include sorbitan higher fatty acid ester and sorbitan higher fatty acid ester ethylene oxide adduct. The amount of the dispersant added is preferably 20% by weight or less in the ink layer. If it exceeds 20% by weight, the thermal decomposition property of the ME polymer may be deteriorated and the ME polymer may be easily affected by temperature.

An ethylene vinyl acetate copolymer can be added to and mixed with the ink layer. As a result, the coating state of the ink layer can be improved, and the adhesion between the ink layer and the base material can be improved. The amount of the ethylene-vinyl acetate copolymer used is preferably 20% by weight or less. If it exceeds 20% by weight, M
There is a possibility that the thermal decomposability of the E polymer will decrease, or the dispersibility of the coloring material will decrease. As the base material, a synthetic resin film such as polyester or polyolefin is used.

Next, a method for producing the ink ribbon is, for example, a method for producing an ink ribbon by applying ink to the surface of a substrate, wherein the ink contains at least a methacrylic acid lower alkyl ester. 70 mol
