Abstract
A write area (10) is formed as a writable area on a recording medium accommodating cassette by a printing process using a printing ink containing a proper amount of protein powder made of natural collagen as a main component. In the write area (10), owing to hydrophilic group of the protein powder, even when something is written therein with a water base pen, its ink can be prevented from being floated therefrom and hence the writing can be carried out satisfactorily.
