Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a base material for a transfer material for painting on a heat-resistant base material, and more specifically to a transfer material that allows a large amount of multicolored designs to be easily painted on the surface of a heat-resistant base material. This relates to a base material for use.

BACKGROUND ART Conventionally, transfer materials formed by printing patterns have been widely used as a means for applying them to heat-resistant substrates such as ceramics, glass, enamel, and metals.

A method of applying heat-resistant base materials to ceramics will be explained as an example.

As a method of applying it to the surface of ceramics, for example, 1) first apply a glaze to the surface of unglazed ceramics, fire it at about 1,300°C, transfer the design using a transfer material, and then apply it to the surface of unglazed ceramics at about 800°C
The so-called overglaze transfer method involves firing at 200°C. First, the design is transferred onto the unglazed ceramic surface using a transfer material, and if necessary, after firing at approximately 500°C to 700°C, a glaze is applied on top. Then, the so-called underpainting transfer method involves firing at approximately 1040°C to 1300°C. ■First, a mixture of glaze and resin is applied to the surface of the unglazed ceramics, and a pattern is transferred onto it using a transfer material. There is a so-called glaze transfer method in which firing is performed at approximately 1040°C to 1300°C.

Conventional transfer materials used in such delivery methods include (i) those made by coating a water-based glue on a base sheet, and (ii) those made by coating a water-based resin on a base sheet. etc.

However, the transfer material obtained using these transfer material base materials, that is, the freezing transfer material obtained using the transfer material base material (i), is not suitable for transfer materials that have water absorption properties such as ceramics. In this case, methods (1) and (2) described above cannot be applied, and the copperplate transfer material obtained using the freezing transfer material and the base material for transfer material (ii) are both heat resistant. This material was extremely unsuitable for production of "inuyaku-ei", which is a sex-based material. This is because when using these transfer materials, it is necessary to apply water to the transfer material and apply it to each transfer object one by one. Therefore, much of this process has to be done manually and is extremely time-consuming. This is because not only is it time-consuming, but it also requires considerable skill, especially when painting on curved surfaces.

In addition, as another base material for transfer material, Japanese Patent Publication No. 53-433
There is one disclosed in Publication No. 31. This transfer material base material has a thin layer with adhesive properties on a base sheet, and in use, a pattern layer is provided on this transfer material base material, and furthermore, a pattern layer with adhesive properties is provided on this base sheet. A second thin layer is provided as a transfer material, and during transfer, two temperatures are set so that the adhesive strength of the two thin layers of the transfer material differs, and the transfer material is separated from the transfer material under each temperature condition. A pattern is transferred from a transfer band to a transfer pad onto the surface of an object to be transferred.

Therefore, when attempting to decorate a heat-resistant substrate using this transfer material, each transfer is performed in a thermostatic chamber that maintains each of the two temperatures, or the time interval from the first temperature is adjusted. Therefore, it was necessary to rely on a method of obtaining a second temperature and performing transfer at that temperature. All of this is time-consuming and is not suitable for continuous production in large quantities.

In view of the conventional problems as described above, the present inventors have sought to obtain a base material for transfer materials that can easily apply a large amount of multicolored designs on the surface of a heat-resistant base material such as ceramics. As a result of various considerations and researches, we have finally completed the present invention. That is, in the present invention, a thermoplastic waxy material layer and a thermoplastic material layer are sequentially laminated on a base sheet, and the thermoplastic waxy material layer and the thermoplastic material layer do not have tackiness at room temperature, but can be made by heating. It is sticky, maintains its stickiness for a certain period of time, and thermally decomposes when fired.
A transfer material for painting on a heat-resistant base material, wherein the two layers have different softening points and melting points, and the thermoplastic waxy material layer has a stronger adhesive force to the object than the thermoplastic material layer. It is a base material for use.

Hereinafter, the transfer material base material according to the present invention will be explained in more detail.

The base material for a transfer material according to the present invention is formed by sequentially laminating a thermoplastic waxy material layer 2 and a thermoplastic material layer 3 on a base sheet 1 (see FIG. 1).

The base sheet 1 may be one that is used as a normal transfer material, and may be paper such as high-quality paper, coated paper, or kraft paper, or a film such as polyethylene terephthalate 1-.

The thermoplastic waxy material layer 2 formed on the substrate 1-1 does not have tackiness at room temperature, but becomes tackiness when heated, maintains its tackiness for a certain period of time, and decomposes thermally by firing. It is something that is formed using something. Such products include thermoplastic hydrocarbon resin or rosin resin as the main component, and also include synthetic alloy wax, oxidized modified wax based on montan wax, paraffin wax, microcrystalline wax, animal and vegetable wax, There are mixtures consisting of wax components such as ethylene copolymers.

Note that the mixture forming the thermoplastic waxy substance N2 is further mixed with mineral oil, animal and vegetable oil, etc. to increase the softening point,
Adjust the melting point, fluidity, etc. as appropriate.

This adjustment is made to facilitate the coating or printing of the thermoplastic waxy material layer 2, and to improve the suitability of the coating or printing of the thermoplastic material layer 3 or pattern layer 4 formed thereon. It is something that is done on a regular basis. The softening point and melting point of the thermoplastic waxy material layer 2 are not specified, but the softening point is 55°C to 60°C.
°C, melting point is 85 °C to 95 °C, difference between the two is 25 °C to 35 °C
It is preferable that the temperature is within the range of .

The thermoplastic material layer 3 formed on the thermoplastic waxy material layer 2 does not have tackiness at room temperature, but becomes tacky when heated, maintains its tackiness for a certain period of time, and is thermally decomposed by firing. It is something that is formed using something. These include synthetic alloy waxes, oxidation-modified waxes, paraffin waxes, animal and vegetable waxes,
Mainly waxy mixtures of thermoplastic hydrocarbon resins, ethylene copolymers, etc., or thermoplastic latin laths, styrene butadiene latex, nitrile butadiene rubber latex, alkyd emulsions, acrylic ester copolymer emulsions, ethylene hynyl acetate Examples include copolymer emulsions, acrylic emulsions, vinyl chloride copolymer emulsions, copolymer emulsions of other thermoplastic resins, hydrocarbon resin and rosin emulsions, etc., singly or in mixtures.

Note that the mixture forming the thermoplastic material layer 3 is further mixed with mineral oil, animal and vegetable oil, etc., to adjust the softening point, melting point,
Fluidity etc. may be adjusted as appropriate.

Also, the softening point and melting point of this thermoplastic material N3 are not specified, but the softening point is 50°C to 55°C, the melting point is 75°C to
It is preferable that the temperature is 85°C, and the difference between the two is within the temperature range of 20°C to 30°C.

This thermoplastic material layer 3 comprises the thermoplastic waxy material layer 2
The composition of the substance is appropriately adjusted so that there is a temperature difference in both the softening point and the melting point. The temperature difference between the softening point and the melting point is not particularly limited, but is preferably within the range of 5°C to 15°C. This is to prevent the thermoplastic waxy layer 2 from being adversely affected when the thermoplastic layer 3 is formed on the thermoplastic waxy layer 2 .

Furthermore, with respect to the adhesion force to the heat-resistant base material to be transferred, the composition of each of the substances is adjusted as appropriate so that the thermoplastic waxy material layer 2 is larger than the thermoplastic material layer 3.

The transfer material exploiter according to the present invention has the above-mentioned configuration, and is used in the following manner.

First, a transfer material 8 is obtained by forming an arbitrary pattern layer 4 on the thermoplastic material layer 3 of the transfer base material by a normal printing method or the like (see Fig. 2-a).

Note that, if necessary, a resin N5 having elastomeric properties may be provided between the thermoplastic material N3 and the pattern layer 4, or further on the pattern N4. This resin layer 5 is used to prevent the pattern layer 4 from collapsing during transfer using a transfer pad 6, which will be described later, and is particularly useful for delicate patterns (see Fig. 2-b). reference).

Next, this transfer material 8 is heated, and the transfer pad 6 is transferred to the pattern layer 4.
(See Figure 3). By this pressure contact, the pattern layer 4 is transferred to the surface of the transfer band 6 (see Fig. 4).
. At this time, most of the thermoplastic waxy layer 2 and the thermoplastic layer 3 are transferred to the surface of the transfer pad 6 along with the pattern layer 4.

Thereafter, the transfer pad 6 and the surface of a heat-resistant base material 7 such as ceramics are brought into pressure contact. Due to this pressure contact, the adhesive thermoplastic waxy material layer 2 transferred to the transfer pad 6 by the pressure contact mainly comes into close contact with the surface of the heat resistant base material 7, and together with the pattern layer 4 and the thermoplastic material layer 3, the thermoplastic waxy material layer 2 has adhesive properties. The mixture transfers to the surface of the base material 7 (see FIG. 5). After that, by firing, the thermoplastic waxy material layer 2 and the thermoplastic material N3 are decomposed,
Only the design is formed on the surface of the heat-resistant base material 7.

In addition, the heat-resistant base material 7 in the present invention refers to ceramics,
Refers to heat-resistant materials such as glass, borosilicate, and metal.

Since the present invention is a transfer material base material that can be used as described above, it has the following effects.

That is, when applying to a heat-resistant base material, if a transfer material using the transfer material base material according to the present invention is used, it is possible to mechanically and continuously apply it using a transfer pad. It is possible to easily provide large quantities of multicolored designs.

Furthermore, when using ceramics as the transfer object, the above-mentioned ■, ■, ■
