Abstract
A method for cold fusion printing of characters. The method employs a hydrochlorofluorocarbon fusing agent within a cold fusion printing process to provide superior characteristics. Prior to fusion, toner is temporarily held to the surface of paper by the difference in electrostatic charge between the toner and the paper. Vapors of the hydrochlorofluorocarbon fusing agent are directed to the toner and act on the toner so as to permanently affix the toner to the paper, more rapidly than in known hot fusion methods and with fewer adverse environmental consequences than result from known cold fusion methods.
