A recent interesting addition to this realm is the use of rosin-based resins in the manufacture of the new generation of inkjet inks, the phase-change inks [118].

The phase change ink composition comprises silica as nucleating agent particles having a particle size from 10 tolOO nm. ... 

Radiation curable phase change ink compositions with a radiation curable fluorescent comonomer and a gellant have been described (49). These compositions offer both document security features as well as potential brand highlight features.

Phase change inks are also sometimes known as hot melt inks (23). They are in a solid phase at ambient temperature, but in a liquid phase at elevated temperature. At the inlqet operating temperature, droplets of liquid ink are ejected from the printing device and when the ink droplets contact the surface of the recording substrate, they quickly solidify to form a pattern of solidified ink drops. 

The state of the art of phase change inks has been reviewed (25). Phase change inks have also been used for postal marking, industrial marking, and labeling (23). 

Phase change inks have also been used in other printing technologies besides inlqet printing, such as gravure printing (27). Namely,... 

Phase change inks that can be used for hot melt piezoelectric inlqet printing processes have been developed. Guanidinopyrim-idinone compounds, such as N-Phenylguanidino-6-heptadecylpyr-imidinone, have been used for the formulation of phase change inks (23). The basic route of s mthesis is shown in Figure 5.21. 

Biorenewable fast crystallizing phase change inks have been developed (41). In these, a crystalline component is selected from a diester from salicylic acid and a biorenewable diol, such as 1,4-but-anediol, or 2,3-butanediol. The ink has a total crystallization time of less than 15 s. 

Curable phase change inks that contain functionalized isosor-bides have been described (42). The functionalization of an isosor-bide with acrylate is shown in Figure 5.26. 

Gellant additives for phase change inks that can provide enhanced spectral transmission and gelation properties are based on amide compounds with aromatic end groups (44). An example is shown in Figure 5.27. Phase change inks may also be used for the...
