| Abstract | ||||
| In this study, modification of an amino polyether with resorcinol-aldehyde condensate was performed using four different aldehydes [formaldehyde, glutaraldehyde, butyraldehyde and 4-(N,N-dimethylamino)benzaldehyde] to give dispersants (1 – 5) to be used as dispersing agents for solvent based inkjet inks. The prepared dispersing agents were characterized using FT-IR and GPC. The optical properties and stability efficiency of the ink formulated with the prepared dispersing agents were investigated. The dispersants (1-5) were evaluated for their efficiency in comparison to commercial dispersing agents used in the market. Formulations of dispersants 4 and 5 showed excellent results in comparison to the commercial dispersing agents and have a good potential as effective dispersing agents for solvent based inkjet inks. | ||||
