た。Printing on the curved surface of a plastic retort food container includes an offset method, a silk screen method, and a thermal transfer method. Of these, the offset method is a method of placing each color on the rubber plate, so the number of colors is limited,
There is a drawback in that it is impossible to print a so-called process pattern in which the color changes continuously. Further, the silk screen method has a drawback that not only the pattern of the process cannot be printed but also the printing speed is slow.

４を被転写体に転写していた。On the other hand, the thermal transfer printing method has an advantage in that a pattern can be printed on a transfer mount by gravure printing and then transferred by heat so that a process printing can be performed. As shown in FIG. 4, the transfer paper conventionally used in this thermal transfer system is such that a printing ink layer 4 is formed at predetermined intervals via a release layer 3 on a transfer mount 21 made of high-quality paper, and further an adhesive layer. 5
Was applied on the printing ink layer 4. Then, the transfer paper was pressed against the transfer target while being heated by a heat roller at about 220 ° C. to transfer the printing ink layer 4 together with the adhesive layer 5 to the transfer target.
しかしながら、従来の熱転写方式による転写紙は、転写

伝導が悪いので印刷スピードが遅いという問題があっ
た。However, the conventional thermal transfer type transfer paper is expensive because it uses high-quality paper as the transfer mount, and the heat transfer of the high-quality paper is poor, resulting in a slow printing speed.
本発明はこのような問題点を解決するためになされたも

A transfer mount made of an axially stretched plastic film having a thickness of 10 to 50 μm, a release layer made of an acrylic or chlorinated rubber resin laminated on the transfer mount, and an ink layer having retort resistance laminated on the release layer. And an adhesive layer having retort resistance laminated on this ink layer.

Any plastic film can be used as long as it does not melt at least at the temperature required for transfer. For example, a polyester film such as polyethylene terephthalate, a polypropylene film, or the like. A polypropylene film is preferable because it is cheaper than a polyethylene terephthalate film, for example.

最低ないしそれに近い厚さが選択され、10〜50μｍ程度
が適当であることが多い。The thickness of the transfer mount differs depending on the temperature of the heat roll, the preheating temperature of the container, the transfer time, etc., but the point is that the minimum thickness that can withstand the heat during transfer or a thickness close to that is selected, and 10 to 50 μm is appropriate. There are many.

を混合したものがある。As the release layer, an acrylic or chlorinated rubber type is used. The printing ink layer, which may be coated with a top coat on the surface of the release layer, is formed of a material having retort resistance. This retort resistance is that the quality is not affected even if it is sterilized by retort at high temperature and high pressure in a steam atmosphere (the same applies hereinafter). The retort-resistant material includes, for example, a mixture of chlorinated rubber with a pigment, titanium dioxide or the like.

インキ層などの各材料等によって異なるが、170℃以上
とすることが好ましい。When printing on a retort container with the transfer printing film for a retort as described above, the temperature of the heat roll needs to be 240 ° C. or lower in order to prevent the transfer backing sheet from melting, and 230 ° C. or lower is particularly suitable. On the other hand, it is necessary to raise the temperature to a certain level or higher for transfer, and this temperature is preferably 170 ° C. or higher, though it depends on each material such as the adhesive layer, the peeling layer and the printing ink layer.

体などで蔽ってそのなかで加熱するようにすることが好
ましい。It can be preheated before thermal transfer, and this preheating temperature is preferably as high as possible within a range that does not adversely affect the container.For example, in the case of a container mainly made of polypropylene, about 90 to 130 ° C is suitable. is there. The preheating means does not matter, and a heater, an infrared heater, hot air or the like can be used. In order to uniformly preheat the container, it is preferable that the container is covered with a box or the like and heated therein.

It has stopped at the position. The laminated tube 10 is continuously supplied from the supply path 11, is loosely inserted in the mandrel 13, and is transferred to directly below the heat roll 7 by the rotation of the rotary plate 14.
Then, the heat roll 7 descends and comes into pressure contact with the laminated tube 10, and transfer is performed while rotating this. After the transfer, heat roll 7
On the other hand, the sensor 9 starts operating to rotate the take-up roll shaft 8 by one pitch of the retort transfer printing film 1. Meanwhile, the rotation of the rotating plate 14 causes the next laminated pipe

A plastic lid (not shown) having a polypropylene layer structure formed by injection molding of 0 μm is welded to the above-mentioned body by high frequency, 320 g of water is filled inside the container, and the upper part of the container is sealed with the same lid to control the pressure. Retort sterilization was performed in a retort kettle at 125 ° C for 15 minutes. As a result, a printed pattern similar to that before the retort was obtained although the glossiness of the surface was slightly lowered.
本発明は、上質紙の替りにプラスチックフィルムを転写
台紙に使用するので印刷コストを低下させることができ
る。また、プラスチックフィルムは熱伝導が良くさらに
被転写体を転写印刷前に予熱するので、美麗かつ転写速
度を従来の５〜10倍にすることができる。According to the present invention, a printing cost can be reduced because a plastic film is used for the transfer mount instead of the high-quality paper. In addition, since the plastic film has good thermal conductivity and the pre-transferred material is preheated before transfer printing, it is beautiful and the transfer speed can be 5 to 10 times faster than the conventional one.
