OPTICALLY READING PRESSURE SENSITIVE COPYING NOTEBOOK

摘要

PROBLEM TO BE SOLVED: To provide an optically reading pressure sensitive copying notebook applied with an ink contained in an optically reading coloring agent microcapsule on the rear side of the upper note having an improved optically reading accuracy by restraining the blur of the developed image to be optically read and improving the coloring density. SOLUTION: A no carbon type optically reading pressure sensitive copying notebook 2 comprising an upper note 4 applied with a coloring agent microcapsule layer 4 on the rear side and a lower note 3 applied with a color developer layers 5 on the surface side, where an ink D contained in an optically reading coloring agent microcapsule 3 having a 2μm or less average particle size is applied at a predetermined part of the upper note rear side, with the optically reading coloring agent microcapsule C is mixed in the coloring agent microcapsule layer 4 in the applied part can be provided.
