PROBLEM TO BE SOLVED: To prevent occurrence of residue and surface stain on a substrate at an unirradiated part at the time of development by using an alkali-soluble resin contg. a copolymer of a specified indene monomer with another copolymerizable monomer. SOLUTION: The radiation sensitive compsn. contains a colorant, an alkali- soluble resin contg. a copolymer of an indene monomer represented by the formula with another copolymerizable monomer, a multifunctional monomer and a photopolymn. initiator. In the formula, X<1> -X<7> are each H, halogen, 1-4C monovalent aliphatic hydrocarbon, 3-8C monovalent alicyclic hydrocarbon or 6-8C monovalent arom. hydrocarbon. The color tone of the colorant is not particularly limited, the colorant is suitably selected in accordance with the use of a formed color filter and any of org. and inorg. colorants may be used. The indene monomer is, e.g. indene or 1-chloroindene. |
