The following formulations are screened in the form of graphic images onto a clay-coated paper and cured using electron beam or ultraviolet radiation. They contain an organic dye which sublimes at temperatures tolerated by the paper. The graphic images are transferred to the surfaces of material which dissolve the dye by contacting the image side of the paper to the surface and heating to sublime the dye. (Image Omitted) The oligomer polymerizes with itself and with the diacrylate at their acrylate groups. The blue dye is CI No. 60725 and is soluble in organic solvents. Coating on the paper and application of radiation may be conventional as the mixture flows readily and cures readily to form a polyacrylate matrix around the dye which is firm but flexible and clean to the touch.
