(54) Process for finishing colour developer paper


(57) A colour developer paper carrying a coating of acid clay colour developing material is finished by passage through a nip between two calendering rolls. Both the calendering rolls are heated to temperatures of at least 50 °C and preferably at least 80 °C.
The process provides a paper of improved smoothness and handleability for use in a pressure sensitive copying system.
