The surface morphology, transparency and thermal properties of the cured hybrid polymer were found to be determined by the monomer structure, solvent, the amount and arrangement of trimethoxysilane groups. The polymer–silica hybrid materials crosslinked with both UV curing and sol-gel reaction exhibited good thermal properties at elevated temperature. Due to the surface activity of monomers in aqueous medium, aggregates on the film made of water diluted monomers are larger than those prepared by solvent diluted monomers. Larger aggregates lead to lower transparency. Hybrid films made of star-like monomer had smaller silica aggregates than those prepared by the linear monomers. Star-like monomer exhibited excellent compatibility with water-based pigment dispersion and good ink-jet printing properties. It can be used to improve the properties of the ink-jet printed micropatterns. In addition, the diacids with phthalimide groups were synthesized to made soluble UV-curable imide-epoxy oligomer that can be used as ink compositions for manufacturing color filter. The chemical structures of soluble oligomers were designed to improve the mechanical strength and thermal properties of the cured films without deteriorating the optical properties. The oligomers(AMPDP) with pendent phthalimide groups showed batter solubility in monomers and batter compatibility with pigments than those oligomer with phthalimide groups on the mainchain. Inks prepared by AMPDP showed good reactivity, printing precision and stability. Parallel lines with straight edger were printed on the glass substrate and fixed by UV curing reaction. These oligomers have the potential as ink compositons for ink-jet printed color filter.
