Abstract
In a process for preparing an acceptor coated sheet used in a pressure sensitive copying system utilizing 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 acceptor in an acceptor layer formed on said base sheet, the base sheet is coated with a composition comprising at least one acceptor and an aqueous emulsion of an oligomer of a hydrocarbon compound having 3 to 10 carbon atoms in total.
