Radiation-sensitive colored compositions, cured colored films, color filters, processes for forming colored patterns, processes for preparing color filters, solid-state image sensors and liquid crystal display devices

Abstract

Herein provided are radiation-sensitive colored compositions suppressing a phenomenon in which a radiation-sensitive colored composition of another color penetrates into previously formed pixels to result in a decrease in the color purity of the previously obtained pixels; cured colored films and color filters using them; processes for forming colored patterns; processes for preparing the color filters; solid-state image sensors; and image display devices. The radiation-sensitive colored compositions comprise a dyestuff, a photopolymerizable compound, a photoinitiator, and a nonionic surfactant containing a partial structure represented by formula (1) or (2) below and having a weight average molecular weight of 2500 or less and an HLB value of 9.2 to 15.5 as determined by Griffin's method. In formula (1) and (2), Rand Reach independently represent a hydrocarbon group containing 8 or more carbon atoms, and n1 and n2 each independently represent 4 to 25.
