A matted transparent paper is obtained by moistening a paper prepared from relatively lightly beaten pulp and then subjecting the moistened paper to a calendering treatment with the use of a heated embossing metal roll having a finely engraved surface with sharp reliefs.

Method for the production of a matted transparent paper and the product

The electrostatic recording material comprises an electroconductive transparent base sheet having a dielectric layer thereon. The base sheet is obtained by moistening a paper prepared from relatively lightly beaten pulp and then subjecting the moistened paper to a calendering treatment with the use of a heated embossing metal roll having a finely engraved surface with sharp reliefs.

Electrostatic recording material and the method of preparing it

A matted transparent paper is obtained by moistening a paper prepared from relatively lightly beaten natural pulp and then subjecting the moistened paper to a calendering treatment with the use of a heated embossing metal roll having a finely engraved surface with sharp reliefs.

The electrostatic recording material comprises an electroconductive transparentized base sheet having a dielectric layer thereon. The transparentized base sheet is obtained by subjecting to a transparentizing treatment with moisture, heat and pressure a fibrous matrix sheet of a mixture of natural pulp with synthetic pulp formed of a blended polymer system consisting essentially of polyvinyl alcohol-acrylonitrile copolymer and acrylonitrile-styrene copolymer.
