Abstract
A pressure-sensitive recording sheet is described. The sheet is comprised of a paper substrate which is treated with succinic acid derivatives having an alkenyl group or alkyl group containing from 4 to 18 carbon atoms, or salts thereof. This pressure-sensitive recording sheet is greatly reduced in the formation of fog which occurs in printing the sheet. Thus, it is very useful as no carbon paper.
