ABSTRACT:
Low fix temperature toners are fabricated by a two step melt mixing and reactive melt mixing process wherein there is initially prepared, for example, using a melt mixing device, a composite of pigment and resin, followed by crosslinking of the resin component at high temperature and high shear to produce a partially crosslinked toner with substantially no unpigmented gel domains. The toners are particularly suitable for high speed fusing, show excellent offset resistance and wide fusing latitude, and superior vinyl offset properties.
