A pigment dispersion includes a pigment and a dispersant, wherein an as formed curable phase change ink having the pigment dispersion added thereto, when filtered using a 1 micron filter at a temperature of 85° C., has a slope of ≧5 g/s and a T2/T1 of ≦1.6, wherein T2 represents a time to filter the last 25 g of a 100 g sample of the phase change ink through the 1 micron filter at 85° C., while T1 represents the time it takes to filter the first 25 g of the 100 g sample of the phase change ink through the 1 micron filter at 85° C.
