40g / m²160 g / m or more²The following is preferred
Things. The elongation of the flexible support of the present invention is 10
% Is over in inkjet printers
When printing, unevenness when traveling with the printer and passing
The original image is distorted or ink is missing due to stretching or abnormal stretching.
It is unfavorable because it frequently occurs.
The thickness of the flexible support in the invention is less than 45 μm
When printing on an inkjet printer
Damage or wrinkles during transfer to fabric, etc.
It frequently occurs and has many practical problems, and when it is 150 μm or more,
Heat transfer from the back of the support during transfer
Insufficient transfer efficiency, which is considered insufficient
Require excessive heating and time for the fabric.
And there is no problem in transferring the image from the transfer paper to the cloth.
In both cases, the texture of the fabric is often impaired. An ink containing a sublimable dye according to the present invention.
As a receiving layer of a jet printer ink, a conventionally known layer is used.
Various ink receiving layer configurations can be used.
For example, fillers and non-peelable materials (such as paper

If less than 50μm, use inkjet printer
At the time of printing at the time of printing and transfer to fabric etc.
Breakage and wrinkles frequently occur, and there are many practical problems.
m, the transfer efficiency at the time of transfer is sufficient.
In many cases, excessive heating and time are required for the fabric.
To transfer the image from the transfer paper to the fabric.
Even if there is no obstacle, the texture of the fabric is often impaired. Departure
