An object of the present invention is to provide a novel electroless plating substrate which is used as a pre-electroless plating treatment step, which can be easily handled by a small number of steps and can be easily formed by photolithography. Paint.nThe solution of the present invention is a photosensitive primer which is applied to a substrate by electroless plating to form a primer for a metal plating film, which comprises: (a) at the molecular end a hyperbranched polymer having an ammonium group and having a weight average molecular weight of 1,000 to 5,000,000, (b) a metal fine particle, (c) a polymerizable compound having three or more (meth)acryl fluorenyl groups in the molecule, And (d) a photopolymerization initiator. |
