<p>An inkable sheet comprises a substrate having on at least one surface thereof an ink absorbant layer comprising a cellulose material and an acid functional resin. Preferably, the acid functional resin comprises an acid functional polyurethane resin or an acid functional acrylic resin such as a polyacrylate/acrylic acid copolymer. In general, the higher the molecular weight of the resin, the better the performance. Further, the more insoluble the resin is in cold water at neutral or acid pH, the better the performance. The ink absorbant layer preferably further comprises a weak organic acid or salt thereof and/or at least one cross-linking agent. There is also disclosed a process for preparing an inkable sheet.</p> |
