Abstract
A material for making a conductive pattern, the material comprising a support and a heat-differentiable element, the heat-differentiable element comprising an outermost layer containing a polyanion and an intrinsically conductive polymer and optionally a second layer contiguous with the outermost layer, characterized in that the outermost layer and/or the optional second layer contains hydrophobic thermocoagulable latex particles in a weight ratio range with respect to the intrinsically conductive polymer in the range of 20:1 to 1:5, the hydrophobic thermocoagulable latex particles are capable upon heating of increasing the conductivity of the heated parts of the outermost layer relative to the unheated parts of the outermost layer and/or changing the removability of the heated parts of the outermost layer relative to the unheated parts of the outermost layer and the heat-differentiable element does not comprise a di- or polyhydroxy organic compound or an aprotic compound with a dielectric constant, ∈, ≧15; a method of making a conductive pattern on a support therewith; and a use of the material for making a conductive pattern in making an electronic circuit in the production of an…
