Abstract (en)

[origin: EP0138342A2] 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 DEG C and preferably at least 80 DEG C. The process provides a paper of improved smoothness and handleability for use in a pressure sensitive copying system.
