Abstract
A low melt toner resin with low minimum fix temperature and wide fusing latitude contains a linear portion and a cross-linked portion containing high density cross-linked microgel particles, but substantially no low density cross-linked polymer. The resin may be formed by reactive melt mixing.
Claims31
A low melt toner resin consisting essentially of linear portions and cross-linked portions, and said cross-linked portions consisting essentially of high density cross-linked microgel particles.
A low melt toner resin produced by a reactive melt mixing process comprising the steps of:
- (a) melting a reactive base resin, thereby forming a polymer melt;
- and
- (b) cross-linking said polymer melt under high shear and high temperature to form a cross-linked toner resin.
