COMPOSITION SENSITIVE TO VISIBLE LIGHT

摘要

A composition highly sensitive to visible light which comprises: (a) a polymer having repeating units of a structure represented by the general formula (I): (I) (wherein R<1>, R<2>, and R<3> are the same or different and each represents (un)substituted alkyl, (un)substituted aryl, or (un)substituted aralkyl, provided that R<1> and R<2> may form cycloalkyl in cooperation with the adjacent carbon atom; and R<4> represents lower alkyl); (b) a compound which generates an acid upon irradiation with visible light; and (c) a sensitizing dye. The composition is useful as a material for forming electronic circuits, lithographic printing material, etc.
