ABSTRACT:
Microcapsule-coated paper for use in a pressure-sensitive copying set contains a higher than conventional filler loading, namely 15% to 23%, based on the total weight of the paper. The use of filler loading levels within this range increases the maximum number of legible copies obtainable in a pressure-sensitive copying set.
