| abstract |
Curable coating compositions useful for protective treatment of elements bearing electrographically-formed toner images are comprised of (a) either (i) a mixture of a siloxy-containing polycarbinol and an acrylated urethane, or (ii) a siloxy-containing acrylated urethane; (b) a multifunctional acrylate; and, optionally (c) a free radical photoinitiator. Toner image-bearing elements, such as electrographic elements and specifically photoconductive recording films, can be provided with a protective overcoat layer which is bonded to the element and which serves to protect the toner image from abrasion and scratches. Such an overcoat layer is provided by coating the element with a curable composition and curing the resulting coating. The protective overcoat layer is applied to the toner image-bearing side of the element. |
