Physical Chemistry and Color Physics of Perylene Pigments

Physical Chemistry and Color Physics of Perylene Pigments [Pg.269]

For the majority of perylene pigments, both color and stability properties derive from electronic k-k interactions. However, for Pigment Violet 29 (6), the unsubstituted diimide, hydrogen bonding between the imide hydrogens and the carbonyl groups is also possible, and is undoubtedly the reason for the added stability of this perylene pigment.

Perylene pigments are hydrophobic in nature. This factor is significant in understanding and manipulating their surface characteristics for optimal dispersion in water and solvent-bome coatings [60]. [Pg.270]
