(57) [PROBLEMS] To provide a high-sensitivity pattern formation by irradiation of radiation, to obtain a high-resolution fine pattern without disconnection, and to digital data by operating a laser or the like. An electrically conductive pattern material capable of forming a circuit directly on a substrate is provided. Also provided is a conductive pattern forming method capable of forming a fine conductive pattern with high resolution on a substrate. A pattern forming material comprising a photosensitive layer containing a photothermal conversion substance and a binder on a support, and a polymer compound having a hydrophilic group directly chemically bonded to the surface of the photosensitive layer. A conductive pattern material characterized by forming a hydrophilic / hydrophobic pattern by irradiating radiation like an image, and then forming a conductive material layer on the hydrophilic region of the hydrophilic pattern, etc. is there. |
