Abstract
The cover of a binder is provided with a coating which is receptive to inks which are water based, solvent based or gel based, and which is substantially water-fast after the ink has dried. A coated transparent sheet may be provided on the front cover of the binder to form a pocket so that visual material inserted in the pocket may be traced, and so that the cover may be personalized. The coating may include porous pigment and a binder which includes as a component a water soluble polymer.
