NO-CARBON PRESSURE SENSITIVE COPYING PAPER

摘要

PURPOSE:To manufacture no-carbon pressure sensitive copying paper preventing a phenomenon, in which a color develops by a reaction with a coat and a supporter when micro-capsules are broken in no-carbon pressure sensitive copying paper (CB) coated with the micro-capsules including an electron donative color developer. CONSTITUTION:In no-carbon pressure sensitive copying paper (CB), in which a coating fluid containing micro-capsules including an electron donative color developer, a buffer material and a binder is applied and dried, ueast desensitizing micro-capsules having yeast including a desensitizer as capsule wall films are used in an undercoat layer formed to the same coat or between the coat and a supporter.
