Abstract
Abstract A recording medium for business machines has an ink-receiving layer provided on a substrate. The ink-receiving layer comprises a highly water-absorbent material in which an organic material selected from acrylic acids and polyacrylic acids and an inorganic material selected from inorganic alkoxides and metal alkoxides are grafted.
