Has been done.

[0003]

The above method is simple and can be used with existing color copying machines, but has the following problems. That is, if the design is not fixed on a non-expandable support such as paper or film, the design will be cracked or cracked. In order to prevent this, when transferring to a stretchable shirt cloth, a thick hot-melt film having a strong film-forming property is used, but this significantly deteriorates the texture and wearing feeling of the cloth. Therefore, an object of the present invention is to provide a thermal transfer method and a transfer medium that can easily form a pattern, do not cause cracks and cracks in the transfer pattern, and do not deteriorate the texture of the fabric and are excellent in wearing feeling. It is in.

[0004]

Means for Solving the Problems As a result of intensive studies, the present inventor has conducted a thermal printer using a heat-sensitive melt transfer ink ribbon containing a sublimable or evaporative dyeing agent, and a thermal printer onto a releasable substrate. After a pattern is formed on a transfer medium in which hot-melt resin is laminated, the transfer medium and the fabric are brought into close contact with each other and heated to dye the hot-melt resin in which the dye sublimated or evaporated is in a molten state. The present invention has reached the present invention by exploiting the simultaneous penetration and fixation of cloth.
