ABSTRACT:
A novel chromogenic composition is produced comprising at least one color precursor dissolved in a carrier oil, the carrier oil being a weakly polar solvent having a boiling point of from about 180.degree. C. to about 300.degree. C., the color precursor being of the electron donor type and being reactive with color developers of the electron acceptor type to form an image and a liquid radiation curable substance, the liquid radiation curable substance being selected from the group consisting of isocyanate modified acrylic, methacrylic and itaconic acid esters of polyhydric alcohols, acrylic prepolymers derived from partial esterification of pentaerythritol with acrylic acid and acrylic acid esters and mixtures thereof, the liquid radiation curable substance being curable to a frangible resin upon exposure to radiation. The coating composition has a viscosity in the range of about 1000 cps. to about 3500 cps. A pressure-sensitive, carbonless transfer sheet is produced comprising a paper substrate having coated thereon a barrier layer and a cured resinous film coated on said barrier layer, the cured resinous film being a radiation cured film of the novel chromogenic coating composition having a frangibility that will permit passage of the color precursor and the carrier oil to the surface of the cured resinous film when the cured resinous film is broken, the color precursor solution being retained as small occlusions within a matrix of closely packed cross-linked molecular chains of cured resin.
