HEAT-SENSITIVE MULTIPLE DUPLICATING PAPER

摘要

PURPOSE:To provide a heat-sensitive multiple duplicating paper of superior preservative stability of a heat-sensitive recording layer of a first recording sheet as an upper sheet which can get simultaneously two sheets of recording of high fastness and high physical recognition by one printing. CONSTITUTION:A duplicating paper is formed by the combination of an upper sheet I provided with a heat-sensitive recording layer A composed of aliphatic acid ferric salt and a chelate agent as main components formed on one face of a base sheet and a heat fusible layer B containing a colorless or light-color basic dye and a heat fusible substance formed on the other face, and a lower sheet II with a heat-sensitive color developing layer C containing a coloration agent for the coloration of the basic dye formed on one face of a base sheet 2.
