PURPOSE:To enable clear copying to be achieved with slight contamination due to pressure or friction, by applying a color developer ink and a capsule ink only to desired parts of base papers by spot printing. CONSTITUTION:A business form 1 consists of three pressure-sensitive printing papers, i.e., an upper-sheet paper 2, an intermediate-sheet paper 3 and a lower- sheet paper 4. The upper-sheet paper 2 is provided with a microcapsule layer 6 of a capsule ink on a desired part of the back side of a base paper 5 by spot printing. The intermediate-sheet paper 3 is provided with a color developer ink layer 7 by spot printing on the face side of a base paper 5 at a part corresponding to the microcapsule layer 6 of the paper 2, and is provided with a microcapsule layer 8 of a capsule ink on a desired part of the back side of the base paper 5 by spot printing. The lower-sheet paper 4 is similarly provided with a color developer ink layer 9 on the face side of a base paper 5 at a part corresponding to the microcapsule layer 8 of the paper 3. Each of the base papers 5 is not limited to an ordinary paper but may be any printable paper form material such as a plastic film. |
