Summary:A process for producing a coated, printed substrate comprising (a) providing a printed substrate, wherein the substrate comprises a surface on which resides one or more areas of a layer of an ink, (b) bringing together a component A and a component B to form a urethane coating composition, wherein component A comprises a polyisocyanate prepolymer A1, wherein the polyisocyanate prepolymer A1 is a reaction product of a polyisocyanate monomer A1a and an isocyanate-polyreactive compound A1b, wherein component B comprises one or more polyol B1, wherein the urethane coating composition has isocyanate index greater than 0.9, (c) applying a layer of the urethane coating composition to the surface. Also provided is a coated printed substrate made by such a method.
