Description

The present invention relates to a combination of a thermal transfer sheet and a transferred body, a method for producing a printed matter, and a printed matter.

Conventionally, various thermal transfer methods have been proposed. For example, there is known a sublimation thermal transfer method that has excellent transparency, high reproducibility of neutral colors and high gradation, and can easily form a high-quality image equivalent to a conventional full-color photographic image.

For the formation of the thermal transfer image by the sublimation thermal transfer method, a thermal transfer sheet having a dye layer provided on one surface of the base material and a receiving layer provided on one surface of the transferred body, for example, the other base material. A thermal transfer image receiving sheet is used. Then, the receiving layer of the thermal transfer image receiving sheet and the dye layer of the thermal transfer sheet are overlapped with each other, and heat is applied from the back surface side of the thermal transfer sheet by the thermal head to transfer the dye of the dye layer onto the receiving layer. A printed matter in which a thermal transfer image is formed on the layer is obtained.

The thermal transfer image receiving sheet used in such a thermal transfer method has various uses, for example, it is used for a card having a face photograph such as an ID card and a credit card, a composite photograph in an amusement facility, a trading card, and the like.

In recent years, an increasing number of imprints have realized a simple three-dimensional shape with irregularities by heating a card containing foamed particles to form an expanded portion. Even in the sublimation type thermal transfer method, the formation of an expanded portion by heating with a thermal head using foamed particles has been studied. However, in the sublimation type thermal transfer method, the heating by the thermal head is instantaneous, the heat is not sufficiently distributed to the foamed particles, and an expanded portion having a desired height cannot be obtained.

As shown, the foam layer 9A is transferred onto the microwave heating layer 34 in a predetermined pattern. The predetermined pattern corresponds to a portion where the surface of the printed matter is desired to be expanded.

Next, the transferred body 30 and the thermal transfer sheet 10A are stacked so that the receiving layer 5A (fourth transfer layer 5) of the thermal transfer sheet 10A and the surface of the transferred body 30 provided with the microwave heating layer 34 face each other. In addition, as shown in FIG. 10, the receiving layer 5A is transferred onto the transferred body 30 so as to cover the microwave heating layer 34.
