Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of transferring a pattern using a sublimation transfer material, and its purpose is to:
To provide a method for transferring a blurred pattern of an arbitrary shape onto the surface of various transfer objects using a simple method.

Conventionally, when obtaining a shading pattern using a sublimation transfer material, a shading pattern is formed on a printing plate in advance at the plate-making stage, and this plate is used to print the transfer material with ink containing a sublimable dye on the transfer material. A method of superimposing them and applying heat transfer painting is used.

However, with this method, the shape of the blurred pattern and the degree of blurring of the blurred pattern are specified by plate making and printing.

Therefore, it is not possible to transfer a blurred pattern having an arbitrary shape and degree of blur onto an arbitrary part, and it is also impossible to transfer a blurred pattern with an arbitrary shape and degree of blurring. When both a striped pattern and an optional gradation pattern are required, there is a problem in that plate making and printing must be performed in accordance with each pattern. As a result of research to eliminate these drawbacks, the present inventor found that the above-mentioned drawbacks could be eliminated by applying a base sheet having heat resistance and plasticity, leading to the completion of the present invention. It is something.

That is, the present invention uses a sublimation transfer material in which an ink containing a sublimable dye is printed on a base sheet 1 having heat resistance and plasticity and a pattern layer 2 is provided on the base sheet 1, and a pockmark pattern of an arbitrary shape is transferred to an area where a pockmark pattern of an arbitrary shape is required. The sublimation transfer material is covered with the material so that ten arbitrary shapes of spaces are created between the material and the sublimation transfer material is removed after heating for a sufficient period of time for the sublimation dye to dye the material to be transferred. The base sheet that can be used in the present invention includes 15
It is necessary to select and use a material that is heat resistant so as not to be damaged, and also has plasticity so that a space of an arbitrary shape can be provided between the object to be transferred and the sublimation photographic material. As these materials, it is possible to use various kinds of soft metal sheets and composite materials made by laminating metal foil and paper, but in particular, composite materials made by laminating metal foil and paper are difficult to print on the paper surface. It is preferable because it has excellent aptitude. Further, as the ink containing the sublimable dye, it is possible to use the ink used for conventional sublimation transfer materials. As explained above, as a result of using a sublimation transfer material using a base sheet having plasticity, the transfer material can be deformed into any shape to create a space of any shape between it and the object to be transferred. Also, since the base sheet has heat resistance, it does not deform during heat transfer unlike the base sheet used in conventional sublimation transfer materials, so it can be applied with a blurred pattern of any shape. It is possible to transfer the image onto the transfer body.

Further, even when both a non-blurred pattern and an optional gradation pattern are required, only one plate making process is required. It has the following effects. EXAMPLES Hereinafter, the present invention will be specifically explained with reference to Examples.

Example 1 A sublimation transfer material was obtained by performing multicolor printing using an ink having the composition shown below on a base sheet made by laminating soft aluminum (15 μm thick) and high-quality paper.

The binder and solvent composition are the same as the yellow ink.

After the sublimation transfer material was embossed into a suction plate shape, it was positioned so that the corrugated plate concave portion was in contact with the surface of the glass fiber reinforced polyester board, heated at a temperature of 200°C for 10 minutes, and after cooling, the sublimation transfer material was removed. As a result, a glass fiber-reinforced polyester board with a continuous striped pattern was obtained.

Example 2 After the sublimation transfer material obtained in Example 1 was embossed into a textured shape, the sublimation transfer material was used to emboss the material so that the textured recesses were in contact with the surface of a metal cosmetic container on which a protective layer of epoxy resin was provided. and heated at a temperature of 180°C for 20 minutes,
When the sublimation transfer material was removed after cooling, a metal cosmetic container with a shading pattern painted on it was obtained.
