PROBLEM TO BE SOLVED: To dispense with measures for enhancing hiding properties and countering light-transmitting properties, to enable prevention of the possibility that winning and failure are determined before the use, while making design properties unrestricted, and further to eliminate disadvantages in productivity and cost. SOLUTION: White capsule-containing ink is made by mixing therein dye capsules 1 coloring in blue, by 25%. The capsule-containing ink is applied on the surface of a base 2 to form a capsule layer 3 (A). Letters of 'winning' are printed on the capsule layer 3 by typographic printing by using color- developing ink which colors in the same white as the capsule-containing ink when printed, so that a color-developing printed part 4 be formed of the printed letters (B). When almost the whole surface of the capsule layer 3 whereon the color-developing printed part 4 is provided is scrubbed by a nail or a coin, the color-developing printed part 4 printed with the color-developing ink develops a color (blue) and appears [(C)] and the letters of 'winning' can be clearly ascertained. |
