A photocurable resin composition is described, which comprises a specific type of photosensitive polymer obtained by copolymerization of a monomer of the following general formula [I] ##STR1## in which R.sup.1 represents H, CH.sub.3 or C.sub.2 H.sub.5, X represents --O-- or --NH--, Y represents a linear or branched hydrocarbon group having from 1 to 4 carbon atoms, and .PHI. represents ##STR2## Z.sup..crclbar., in which Z.sup..crclbar. represents an anion, and R.sup.2, R.sup.3 and R.sup.4 are independently an alkyl group having from 1 to 4 carbon atoms, and a monomer of the following general formula [II] ##STR3## in which R.sup.5 represents H, CH.sub.3 or C.sub.2 H.sub.5, and n and x are independently an integer of from 1 to 4. The photosensitive polymer is photocrosslinked with a diazide compound. The resin composition is particularly suitably for use in formation of a color filter because of good dyeability and good adhesion to a substrate.

A photo-setting resin composition having a good storage stability; using no hexavalent chrome; having well-balanced photosenstive and dyeing properties; capable of being developed with an aqueous solvent; and having a superior resolution when a color filter is formed, is provided, which composition is obtained by copolymerizing as effective components, a monomer expressed by the formula ##STR1## wherein R.sup.1 represents H, CH.sub.3 or C.sub.2 H.sub.5 ; X represents --O-- or --NH--; Y represents a linear chain or branched hydrocarbon group of 1 to 4 carbon atoms; .PHI. represents ##STR2## wherein R.sup.2 and R.sup.3 each represent an alkyl group of 1 to 4 carbon atoms and Z.sup..crclbar. represents an anion,

Photo-setting resin composition

A method for producing plasticizers which contain titanium in only a very small amount is provided. According to this method, the amount of waste water is very small. This method comprises reacting phthalic anhydride with an alcohol having 4-18 carbon atoms in the presence of, as a catalyst, a tetraalkyl titanate or a polymer thereof, and has a feature in the treatment of the resultant ester with a solid alkali and adsorbing agent(s) in the absence of water.
