<P>PROBLEM TO BE SOLVED: To provide a photosensitive composition having high sensitivity, high resolution and proper storage stability and capable of forming a high-definition permanent pattern having proper various properties required, a photosensitive film, a permanent pattern forming method that uses the photosensitive composition, and a printed circuit board on which a pattern is formed by the permanent pattern forming method. <P>SOLUTION: The photosensitive composition comprises a binder, a polymerizable compound, a photopolymerization initiation compound and a thermal crosslinking agent, wherein the photopolymerization initiation compound comprises a merocyanine compound and an oxime derivative. The photosensitive film has a photosensitive layer, comprising the photosensitive composition on a support, the permanent pattern forming method includes exposing of a photosensitive layer formed from the photosensitive composition, and the printed circuit board is formed by the permanent pattern forming method. <P>COPYRIGHT: (C)2008,JPO&INPIT |
