Patent ID: 6849370

Claim:
A process of printing an image using an electrographic printer and an energy reactive toner, comprising the steps of: a. preparing a toner comprising at least one compound comprising active hydrogen, at least one compound comprising at least one functional group which is capable of reacting with said active hydrogen, a reactive fusing agent, and at least one protecting agent that protects said toner by inhibiting a reaction between said at least one compound comprising active hydrogen and at least one compound comprising at least one functional group which is capable of reacting with said active hydrogen during storage and printing of said toner; b. supplying an electrographic printer with said toner; c. printing a portion of said toner by means of said electrographic printer onto a first substrate so that printed toner is present on said first substrate; and d. subsequently applying energy to said printed toner to remove protection provided by said protecting agent, and reacting said at least one compound comprising active hydrogen and at least one compound comprising at least one functional group which is capable of reacting with said active hydrogen, wherein said reactive fusing agent liquefies upon the application of energy to said printed toner and accelerates the reaction between said active hydrogen and said at least one compound comprising at least one functional group which is capable of reacting with said active hydrogen.
