摘要:
Disclosed is an organic phase change carrier and a method for forming same, and a phase change ink including same. The organic phase change carrier comprises a colloidal dispersion of nanoparticles exhibiting a substantially uniform distribution of said nanoparticles discretely distributed therewithin, at least one curable monomer; a phase change inducing component, and an initiator. The organic phase change carrier exhibits a substantially uniform distribution of the nanoparticles so that they are discretely distributed therewithin, and are substantially resistant to the aggregation of the nanoparticles distributed therewithin.

摘要:
A process or method for forming silane esters that is substantially free of oligomers. The process includes reacting an anhydrous salt of a carboxylic acid with a silane in a two phase reaction system. The silane comprises a halo-alkyl substituent. The two phase reaction system comprises a first solvent and a second solvent, wherein the second solvent is a solvent that is substantially non-miscible in the first solvent. An imaging member produced utilizing the silane esters so formed are also produced herein.
