Abstract:
The present invention addresses the problem of providing a production method for a laminate having a conductor pattern, the method enabling production of a laminate having a conductor pattern having an excellent shape. This production method for a laminate having a conductor pattern comprises: a bonding step for bonding a transfer film which sequentially has a temporary support body, an intermediate layer, and a photosensitive layer to a substrate which has on a surface thereof a metal layer such that the photosensitive layer side comes into contact with the metal layer; an exposure step for pattern-exposing the photosensitive layer from a side opposite to the substrate side; a development step for executing development on the exposed photosensitive layer by using an alkaline developing agent and forming a resist pattern; an etching step for performing etching on a portion of the metal layer at a region where the resist pattern is not disposed or a plating step for performing plating on said portion; and a resist stripping step for stripping the resist pattern. The method further comprises, if comprising the plating step, a removal step for removing the metal layer exposed in the resist stripping step and forming a conductor pattern on the substrate. The method further comprises, between the bonding step and the exposure step or between the exposure step and the development step, a temporary support body stripping step for stripping the temporary support body. The photosensitive layer includes a crosslinkable alkali-soluble resin, an ethylenically unsaturated compound, and a photoinitiator.
