<P>PROBLEM TO BE SOLVED: To provide a photosensitive composition having a long pot life, excellent in tackiness, plane trouble, surface shape and edge roughness, having high sensitivity, high resolution, excellent resistance to electroless gold plating and excellent property of filling via and through holes, and capable of efficiently forming high-definition permanent patterns (such as a protective film, an interlayer insulation film and a solder resist pattern), by specifying a binder and a heat crosslinking agent used together with the binder, and to provide a method for preparing the photosensitive composition, a photosensitive film, a photosensitive laminate, a permanent pattern forming method using the photosensitive laminate, and a printed circuit board on which a permanent pattern is formed by the permanent pattern forming method. <P>SOLUTION: The photosensitive composition comprises a binder, a polymerizable compound, a photopolymerization initiator, a pigment and a heat crosslinking agent and has an average particle diameter of particles being ≤2 μm. There are also provided the method for preparing the photosensitive composition, the photosensitive film, the photosensitive laminate, the permanent pattern forming method using the photosensitive laminate, and the printed circuit board on which a permanent pattern is formed by the permanent pattern forming method. <P>COPYRIGHT: (C)2008,JPO&INPIT |
