Method of producing pattern member, apparatus of producing pattern member, and pattern member

An apparatus of producing a pattern member that has a multi-color pattern made of color inks of a plurality of colors on its surface by repeating, at frequency corresponding to the number of the plurality of colors, an operation of overlapping on a given substrate a plurality of single color films each having a different color of the plurality of colors and a color ink layer formed on its surface, to transfer the color ink layer on the single color film to the substrate, the apparatus comprising:

• transferring means corresponding to the number of the plurality of colors, transferring the color ink layer of the single color film to the substrate, the transferring means being constituted of a patterning roll having a convex portion of given pattern formed on its surface and a facing roll placed facing the patterning roll so that the patterning roll and facing roll sandwich both the substrate and the single color film between them;
• substrate feeding means sequentially feeding the substrate to the transfer corresponding to the number of the plurality of colors;
• and
• single color film feeding means corresponding to the number of the plurality of colors, feeding a single color film of one color among the single color films of the plurality of colors, between the patterning roll and the substrate fed to a nip portion sandwiched by the patterning roll and the facing roll, such that the color ink layer of the single color film overlaps on and comes in contact with the substrate.

A method of producing a pattern member comprising the steps of:

• forming a plurality of single color transfer materials each having one of a plurality of colors, by forming a coloring material layer of each color on each of a plurality of transfer substrates;
• forming a pattern by a process in which each surface of the single color transfer materials of the plurality of colors is pressed by a pressing member having irregularity of given pattern formed on its surface, to form an irregularity pattern corresponding to the irregularity of the pressing member on the surface of the single color transfer material;
• and
• transferring a part of the coloring material layer to the transfer substrate to produce a pattern member having a multi-color pattern of the plurality of colors on the substrate by repeating, at frequency corresponding to the number of the plurality of colors, an operation in which the surface of the single color transfer material of one color among the single color transfer materials of a plurality of colors having an irregularity pattern formed is overlapped on a given substrate and the coloring material layer at the convex portion of the single color transfer material is transferred to the substrate.
