Abstract
The object of the invention is to provide a multi-layer ink ribbon having a long printing life and a substantial freedom from causing unevenness of prints and a process for manufacturing the above ink ribbon. In accordance with the invention, a plurality of webs each constructed by using multifilament yarns for both warp and weft are superposed and fuse-cut to the width of a ribbon. At least one of the webs is compressed by hot pressing in advance and assembled with at least one web either not hot-pressed or hot-pressed to a degree of compression different from the first-mentioned hot-pressed web. The resulting assembly is fuse-cut under pressure to the width of a ribbon and the ribbon thus obtained is inked.
