Abstract:
Cross-linked toner resin having linear portions and cross-linked portions of high density microgel particles, where the toner resin is an unsaturated polyester resin, is prepared using a liquid chemical initiator such as 1,1-bis(t-butyl peroxy)-3,3,5-trimethylcyclohexane so that the cross-linked resin achieved contains less than 0. 20 percent by weight of acids. In particular, the cross-linked toner resin is free of benzoic acid. The method of making the cross-linked toner resin includes (a) spraying the liquid chemical initiator onto the unsaturated polyester resin prior to, during or subsequent to melting of the unsaturated polyester resin to form a polymer melt; and (b) subsequently cross-linking the polymer melt under high shear to form the cross-linked toner resin.

Abstract:
A die for the preparation of a toner resin in an extruder having a housing defining a housing aperture therein and a conveyor for conveying the resin through the housing aperture to form a stream of resin is provided. The die includes a member connected to a first end of the housing. The member defines an opening therethrough. The member includes a splitter disposed adjacent the opening for splitting a stream of resin passing through the opening in a first direction into two separate streams of resin.

Abstract:
Clear toner compositions for use in offset lithography (or offset printing). Such clear toner compositions exhibit desirable properties, including for example, having low haze level.
