A process for producing a colorant containing highlighted coated substrate by embossing the surface of the substrate, coating this entire surface of the embossed substrate with a radiation curable fluid coating composition containing from about 0.01 to about 15 weight percent colorant, exposing the coated substrate to ionizing or non-ionizing radiation to initiate the desired radiation cure of the coating, continuing to irradiate the substrate until the entire coating hardens, and recovering a coated substrate on which the coating follows the embossed surface and in which the recessed areas are highlighted with the colorant.

Process for producing a colorant containing highlighted coated substrate

Tetraethylorthosilicate or tetraethoxyethylorthosilicate is employed as a low-toxicity diluent in radiation curable coating compositions containing acrylyl or methacrylyl functional oligomer. The orthosilicate compound imparts improved leveling and surface characteristics to said coating compositions.
