Method for modification of surface of pressure-sensitive adhesive with

This invention relates to a conducting organic polymer formed by doping an organic polymer with a protonic acid having a dissociation constant value pKa of less than 4.8, wherein the organic polymer has, as the main repeating unit, a compound represented by the general formula: ##STR1## wherein, m and n, respectively, show the molar fraction of the quinonediimine structural unit and phenylenediamine structural unit in the repeating unit, and 0&lt;m&lt;1, 0&lt;n&lt;1, and m+n=1; and the organic polymer is soluble in an organic solvent in the undoped state, and has an intrinsic viscosity �.eta.! of more than 0.4 dl/g measured in N-methyl-2-pyrrolidone at 30.degree. C. This invention also relates to a film formed of the conducting organic polymer and a conducting organic polymer composition.
