Physicochemical colourants effects on polymeric composites printing toner
Abstract
Purpose
This paper aims to report on production of the colour digital printing toners cyan, magenta and yellow. Colour digital electrophotographic printing is currently in high demand. The provision of a large colour gamut depends on appropriate selection of precise colourants to produce toner capable of producing a thin layer on paper.
Design/methodology/approach
Printing toners were synthesised by the emulsion aggregation method, and then evaluated for chemical constitution and effects of the colourant substituents.
Findings
Results demonstrated that increasing the polarity of a pigment produced better dispersion and lower particle size with narrower distribution and even better colour reproduction. While, changing a pigment’s characteristics did not affect the toner shape or its thermal properties.
Practical implications
The developed method provides a simple way to synthesise colour printing toner.
Social implications
Emulsion aggregation toners provide less hazardous materials during printing.
Originality/value
Evaluations of the influence of solid-state parameters and physicochemical properties of the pigments on printing toner characteristics were done for the first time.
