<P>PROBLEM TO BE SOLVED: To provide a pattern forming material capable of obtaining high sensitivity and a satisfactory resist pattern shape, superior in insulation reliability, and capable forming a high-definition pattern, and to provide a pattern forming method employing the same and a printed board on which a permanent pattern is formed by the pattern forming method. <P>SOLUTION: The pattern forming material includes a photosensitive layer formed by using a photosensitive composition at least including a binder, a polymerizable compound, and a photopolymerization initiator, wherein absorption at 810 cm<SP>-1</SP>per 1 μm thickness of the pattern formed by at least exposing the photosensitive layer after the photosensitive layer is stacked on the surface of the board is <0.02. The pattern forming method employing the pattern forming material and the printed board on which the permanent pattern is formed by the pattern forming method are provided. <P>COPYRIGHT: (C)2008,JPO&INPIT |
