PRESSURE SENSITIVE PAPER AND COPYING SET USING SAID PAPER

摘要

PURPOSE: To increase a copying allowable number without lowering various characteristics of paper by mixing a specific amount of an inorganic filler. CONSTITUTION: Microcapsule-coated paper for use in a pressure-sensitive copying set contains one type of inorganic filler. In this case, a mixing amount of the filler is about 15 to 23 wt.% or preferably 18 to 22 wt.% based on the total weight of the paper. Particularly, the paper is suitable for transfer copying paper and can also be applied to a self-contained type microcapsule-coated pressure-sensitive copying paper. The microcapsule-coated paper is also used as an upper sheet of a copying set or an intermediate sheet.
