Phase change inks comprising novel crystalline compounds

摘要

A phase change ink composition suitable for ink jet printing, including robust printing on coated paper substrates. In embodiments, the phase change ink composition comprises both a crystalline compound and an amorphous compound which are derived from bio-renewable materials. In particular, the present embodiments provide novel crystalline compounds with at least two aromatic moieties for use in the phase change inks.
