<p>A method is described for providing a substrate with a writing surface which will accept slow-drying and/or water-based inks which cannot be easily smudged. The substrate is provided with a writing surface by applying to it a coating comprising an adhesive medium and a pigment in a conventional manner, but before the coating has dried or set, a dry, powdery, absorbent material is applied to the coating by spraying, puffing, or brushing or by roller or other means so as to provide the coating with an absorbent layer which readily accepts slow-drying or water-based inks.</p> |
