Pigment-dispersed resists for color filters

Water-soluble pigment-dispersed resist systems of red, blue, and green were developed using a high polymer as dispersing agent. The color filters formed from the color resists have high photosensitivity, high resolution, high transparency and chromaticity that meets the requirements of color display. The formation of microimage depends not only on the degree of photo-crosslink of polyvinyl alcohol/stylpyridinium (PVA-SbQ), but also on the adhesion of color filter to the glass substrate. The reduction of photoreaction speed of the color resists is caused by the pigments' absorption of UV light. The adhesion between the color filter and glass surface depends on the amount of hydrogen bonds formed between them.
