Patent ID: 8252364

Claim:
A method of forming a metal pattern, comprising the steps of: (I) forming on a substrate a polymer layer in a pattern form by using a compound which has a polymerizable group and a functional group that interacts with an electroless plating catalyst or a precursor thereof; (II) adding the electroless plating catalyst or precursor thereof to the polymer layer; and (III) forming a metal layer in the pattern form by electroless plating, wherein the step (I) further comprises: a step (I-3-1) of forming on a base material a photosensitive layer containing a light to heat conversion substance selected from the group consisting of a dye, a pigment, and a metal fine particle that have a maximum absorption wavelength in an energy exposure wavelength region of 760 to 1,200 nm, and a binder, and forming a polymer layer by using a compound which has a polymerizable group and a functional group that interacts with an electroless plating catalyst or a precursor thereof directly onto the entire surface of the photosensitive layer; and a step (I-3-2) of forming, in the pattern form, a polymer layer that interacts with the electroless plating catalyst or precursor thereof by irradiating the polymer layer with radiation in the pattern form and ablating the photosensitive layer.
