Abstract

The present invention provides transparent film sheets for use in projection by an OHP which can be used both in dry copying and in the ink-jet printing of characters and/or pictures, can be directly printed with a jet printing ink without the intervention of a layer receptive to the jet printing ink, can be disposed of in a state capable of maintaining secrecy after use without the necessity of being shredded, and can be disposed of as a class of recycling waste like common white paper. Specifically, the present invention provides transparent film sheets formed of a cellulose ether derived from cellulose which is the basic component of common paper.
