Abstract
This invention relates to a solid curable composition formed by adding finely divided urea in amounts ranging from 10 to 70 weight percent of the composition to liquid polyene/polythiol curable systems wherein the combined polyene and polythiol contain at least 20 percent by weight of oxyethylene units. The thus formed solid compositions are readily cured by radiation, e.g., high energy ionizing radiation or U. V. radiation in the presence of a photocuring rate accelerator.
