A macromolecular material composition which comprises a macromolecular material and a modifier which comprises a polyvinyl cyclohexane compound having hydroindane structure. The modifier improves melt flow characteristics, flexibility at a low temperature, and mechanical characteristics, such as bending modulus and bending strength, of the material, and do not bleed or give bad smell.

Macromolecular material composition and a modifier for macromolecular

A color filter having excellent optical properties can be produced in high yield using a photo-sensitive composition comprising (a) a resin, (b) one or more pigments, (c) one or more monomers, and (d) a photoinitiator to form a film on a substrate, followed by exposure to light and development using a specific developer containing ##STR1## wherein R.sup.1 is C.sub.1-19 alkyl; and R.sup.2 is C.sub.1-19 alkylene.

Production of color filter

In a colored image forming material comprising (a) a copolymer containing a carboxyl group, (b) a coloring agent, (c) a monomer containing at least one photopolymerizable unsaturated bond in the molecule, (d) a photoinitiator and, when required, (e) a specific sensitizer, the dispersion stability of pigment and the optical sensitivity can be considerably increased by using a specific copolymer of styrene derivative-maleic acid derivative as component (a) and specific benzoimidazole or benzothiazole as component (e), and a photosensitive element or a color filter with distinguished optical characteristics can be obtained therefrom.
