Abstract
Improved process for producing a support for recording material comprising the steps of calendering a base paper including 1.8%-10.0% water content under nip pressure from 400 kg/cm to 3000 kg/cm at the roller temperature from 10.degree. C. to 140.degree. C., and extusion coating the base paper with melted thermoplastic resin is proposed. The support produced by the process is superior in surface smoothness and glossiness. Upon using it for a recording material, excellent image with less unevenness can be obtained without using heat calendering at excessively high temperature after the coating.
