Abstract

Disclosed is a process for making a toner comprising the steps of melt-blending a resin and a colorant and subsequently grinding ther blend after cooling, wherein the improvement com­ prises simultaneously cross-linking the resin during the melt-­ blending step by melt-blending the resin and colorant, at a temperature sufficient to cross-link the resin, in the pres­ ence of a polyfunctional azide having the formula


(N₃ O)y-R-(SO₂N₃)z
where R is an organic radical, y and z are integers from 0 to 10, and the sum of y and z is an integer from 2 to 10.
