A method of reusing a coated substrate having a surface coating fixed to the material substrate surface, comprising the steps:(a) allowing the coated substrate, which carries deposits on its surface, to swell as a coated composition to which said deposits adhere, and(b) drying said coated substrate to reuse said coated substrate wherein the coated substrate comprises a material substrate and a coating composition fixed to the surface of said material substrate, said coating composition comprising a crosslinked water swellable hydrophilic resin which is solid in air at ambient temperature and from which surface deposits are readily removable, such that said coated material substrate is reusable, and wherein the condition of said swellable hydrophilic resin is such that while said hydrophilic resin swells in the presence of water it is not washed away from said surface of said material substrate by water when the deposits are readily removed with water. The method includes the features that (i) said water swellable hydrophilic resin is capable of swelling to a volume at least 1.5 times its initial volume (ii) and said deposits include toner ink.
