ABSTRACT:
The present invention provides a visible light-sensitive composition which is highly sensitive to a visible light and is useful as an electronic circuit forming material, a lithographic printing material, etc., said visible light-sensitive composition comprising (a) a polymer comprising a repeating unit represented by general formula (I):wherein R1, R2, and R3are the same or different and each represents substituted or unsubstituted alkyl, substituted or unsubstituted aryl, or substituted or unsubstituted aralkyl, or alternatively R1and R2form cycloalkyl together with the adjacent carbon atom, and R4represents lower alkyl, (b) a compound that generates an acid by visible light irradiation and (c) a sensitizing dye.
