(54) | Improvements in or relating to writing surfaces |
(57) 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. |
