Abstract
A material for making an electroconductive pattern, the material comprising a support and a light-exposure differentiable element, characterized in that the light-exposure differentiable element comprises a conductivity enhanced outermost layer containing a polyanion and a polymer or copolymer of a substituted or unsubstituted thiophene, and optionally a second layer contiguous with the outermost layer; and wherein the outermost layer and/or the optional second layer contains a monodiazonium salt capable upon exposure of reducing the conductivity of the exposed parts of the outermost layer relative to the unexposed parts of the outermost layer and a method of making an electroconductive pattern.
