ABSTRACT:
Coloring compositions for use in the formation of transparent colored micro-patterns are provided. They comprise colorants, thermosetting or photosensitive resin materials and extenders having an average particle size of not more than 300 nm. The compositions are useful for the fabrication of color filters to be used for display elements such as liquid crystal display (LCD) and solid state imaging devices such as charge-coupled device (CCD). The formed patterns have lower fluctuation in colored layer thickness all over the patterns, superior layer flatness, color levelness and sharpness of pattern boundaries, as well as large purity, clarity and color brightness.
