ABSTRACT:
A pressure-sensitive copying paper of "transfer to plain paper" type obtained by coating a mixture comprising (a) a colorless to light-colored electron-donating color former, (b) a colorless to light-colored electron-accepting color developer giving a colored product by reacting with said color former (a), (c) a wax and (d) a polyvinyl ether, on one side of a support and drying the coated support, provides an advantage which conventional copying papers of "transfer to plain paper" type do not possess, in that the density of a transfer image formed on a plain paper is higher than that of a reverse image formed on the coated side of a copying paper.
