A process for preparing a substantially transparent conductive layer configuration
on a support, the layer configuration comprising in any order at least a first
layer containing an intrinsically conductive polymer optionally containing structural
units represented by formula (I):
##STR1##
wherein n is larger than 1 and each of R1 and R2 independently
represents hydrogen or an optionally substituted C1-4 alkyl group or
together represent an optionally substituted C1-4 alkylene group or
an optionally substituted cycloalkylene group, preferably an ethylene group, an
optionally alkyl-substituted methylene group, an optionally C1-12 alkyl-
or phenyl-substituted ethylene group, a 1,3-propylene group or a 1,2-cyclohexylene
group; and a second layer consisting of a non-continuous layer of conductive silver,
the process comprising the step of: preparing the second layer by a photographic
process; and light emitting diodes, photovoltaic devices, transistors and electroluminescent
devices comprising a layer configuration prepared according to this process.
