The method using a solvent among the coating methods described above requires a drying line and an expensive solvent recovery device to be provided in the manufacturing process. There are disadvantages such as requiring explosion-proof equipment and the solvent may have an adverse effect on the human body. Although the hot-melt method does not have the above-mentioned drawbacks and is superior to the method using a solvent, it has problems in that the coating must be carried out at a high temperature of around 100° C. and that it is difficult to obtain a uniform coating layer.

ができる。 The key point of the present invention is to use a roll similar to a gravure printing plate (hereinafter referred to as a gravure roll) having a large number of minute recesses on its surface, to once adhere a molten coloring material composition to the surface and then transfer it to the support surface. After properly selecting the diameter, depth, density, etc. of the recess and adhering the coloring material composition, the roll surface is rubbed with a doctor blade to remove excess deposits and the color inside the recess is adjusted. By leaving only the material composition, it is possible to uniformly and accurately control the amount of the composition adhered per unit area, and thus the amount of the composition transferred onto the support.
