An inkjet recording material comprises a substrate coated with an ink receiving composition. The substrate may be non absorbent eg. cellulose acetate, polyethylene, polypropylene, PVC, polycarbonate, polyester or a resin coated or barrier coated paper. The ink receiving composition comprises silica (synthetic, ca. 50 micron), a water soluble acrylate (acrylic, methacrylic or maleic acid polymers or copolymers, especially styrene or acrylate ester copolymers) and a basic polymer (polyamine, polyimine and especially a vinyl imidazole / vinyl pyrrolidone copolymer). The composition may also include surfactants, antifoams, optical brighteners, UV stabilisers and other additives. The substrate may be treated eg. by corona discharge or by application of a primer layer, to improve adhesion of the coating. The primer layer may comprise an acrylic modified polyurethane, cross-linked with a polymeric aziridine. In use the recording material may be printed upon, left to dry and then laminated to a transparent protective film. |
