摘要： A process for preparing an acceptor coated sheet used in a pressure sensitive copying system is disclosed. The pressure sensitive copying system utilizes a color forming reaction on a base sheet between the color former in the form of the oily core material encapsulated in microcapsules and the organic acceptor included in an acceptor coating layer formed on said base sheet. The acceptor coating layer includes as a binder a carboxylic latex having an oil swellability smaller than 65% in terms of the swelling with the oily core material. An ester of an organic acid is further included within the microcapsules and/or in the acceptor coating layer.
