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 R3 are the same or different and each represents substituted or unsubstituted alkyl, substituted or unsubstituted aryl, or substituted or unsubstituted aralkyl, or alternatively R1 and R2 form cycloalkyl together with the adjacent carbon atom, and R4 represents lower alkyl, (b) a compound that generates an acid by visible light irradiation and (c) a sensitizing dye.
本发明提供了一种对可见光高度敏感并可用作电子电路形成材料、平版印刷材料等的可见光敏感组合物,所述可见光敏感组合物包括 (a) 由通式(I)代表的重复单元组成的聚合物:
其中 R1、R2 和 R3 相同或不同,各自代表取代或未取代的烷基、取代或未取代的芳基、取代或未取代的芳烷基,或者 R1 和 R2 与相邻碳原子一起形成环烷基,R4 代表低级烷基;(b) 通过可见光照射产生酸的化合物;(c) 感光染料。
