Abstract of the Disclosure A process is provided for producing a pressure-sensitive carbonless transfer or record sheet comprising the steps of preparing a liquid chromogenic coating composition by mixing chromogenic material with a liquid radiation curable substance, the chromogenic material comprising either an acidic color developer of the electron donator type or a color precursor of the electron accepting type. The liquid coating composition is coated onto a web or substrate at a coat weight of from about 0.2 pounds to about 8.0 pounds per 3300 square feet of substrate. The coated web is then exposed to radiation for a time sufficient to cure the liquid coating composition to a tack-free film. A novel liquid chromogenic coating composition is produced, the coating composition comprising a chromogenic material and a radiation curable substance. A pressure-sensitive copy sheet is produced, the copy sheet comprising a substrate having a plurality of surfaces at least one of the surfaces being coated with a tack-free film, the film comprising a radiation cured resin concaining a chromogenic material dispersed.
