Abstract (en)

[origin: GB2437714A] A composition comprising a prepolymer, at least one monomer, a photoinitiator and a levelling additive, the composition being free from any surface-modifying additives that would interfere with printability and the cured composition being water-insoluble and non-absorbing to water, is applied to one side of an optical disc and is then radiation-cured e.g. with UV or electron beam. The levelling additive may be a polymeric acrylate, a mineral oil blend, a low temperature wax dispersion or a paraffinic wax dispersion which is free of silicone. The prepolymer may be an epoxy acrylate, an acrylated oil, a urethane acrylate, a polyester acrylate, a polyether acrylate, an acrylated amine, an acrylic saturated resin, an acrylic acrylate, a cycloaliphatic epoxide, a phenol epoxy novolac or an acrylated epoxidised soya bean oil. The monomer may be an acrylate, methacrylate, a vinyl compound, or a compound capable of polymerising by a ring-opening mechanism. The resulting coated surface is durable and receptive to printing using a radiation-curable ink jet ink.
