Title:
PRESSURE-SENSITIVE COPY LAMINATE
Document Type and Number:
Japanese Patent JP3042311
Kind Code:
B2
Abstract:
PURPOSE: To provide a pressure-sensitive copy laminate which has an upper side sheet, an intermediate sheet and a lower side sheet and in which incorrect rewriting at the intermediate sheet and the lower side sheet is prevented.
CONSTITUTION: An intermediate sheet 2 and a lower side sheet 3 have color developer layers 22, 31 and developer layers 23, 32 in such a manner that the developer is formed of self-color developing color developable sheet in which the developer is microencapsulated and fluorescent ink layers 11, 21 are formed substantially at the same position of the rear surface side of the sheets 1 and 2. Information described at the intermediate sheet cannot be erased by an eraser, etc., and information described by a ballpoint pen is different in color from information formed of the self-color developed color developing part and the fluorescent ink layer, and hence confirmed by visual observation. Even if the intermediate sheet is extracted from another set and the information of the lower side sheet is intended to be falsified by using it, the falsified information is described by self-color developing on the intermediate sheet of the another set, and hence it can be prevented by severely managing the pressure-sensitive copy laminate.
