We demonstrate the preparation of photoresist-based colorant inks with nanoparticle pigments by chemical route and its influence of pigment particle size in nanometer on chromaticity and light transmittance of printed organic films on color filters. The synthesized photoresist-based ultraviolet curable inks with pigments in nanosize exhibit better physical characteristics of jetting, wetting, and curing, and can be used significantly to fabricate color filters with organic films by inkjet printing process. The light transmittance of the prepared organic films on color filters prominently increases with decreasing particle size of pigments, while the magnitude in range of color gamut of color filters increases within optimum nanoscale pigments in particle size. This verifies that size effect of nanoparticle pigment in colorant ink is remarkable on chromatic and optical characterization of printed organic films.
