Abstract:
The invention relates to a conductive polymer composition comprising A) graphite and/or at least one graphite compound, B) at least one binding agent and C) at least one polyurethane dispersion resin, in addition to a multilayered electrode material containing one such polymer composition, and also a method for producing said electrode material and the use thereof.
Abstract:
In order to improve contrast in diazofilms, the diazo compounds in the light-sensitive layer which are to be activated by exposure for colour formation are supplemented by diazo compounds in the case of which nitrogen remaining at the exposed locations and bubbles causing light scatter are produced after the action of light followed immediately by a heat treatment.

Abstract:
Electrode materials suitable for electrochemical cells containing a) a polymeric binder which is composed essentially of polyisobutene having a limiting viscosity number of from 551 to 661 g/cm3 and b) a solid which is capable of reversibly taking up or releasing lithium ions in an electrochemical reaction.
Abstract:
Electrodes suitable for electrochemical cells are produced by a) applying a mixture comprising alpha ) a solid III which can reversibly take up or release lithium ions in an electrochemical reaction and beta ) a binder IV, or a compound which can be converted into a binder IV, to an electrically conductive support V by means of a coating apparatus II with essentially linear relative motion (R) of the support V relative to the coating apparatus II in such a way that an uncoated zone remains on the support V at each of the two margins of the coating apparatus II running parallel to the relative motion (R) and b) cutting the support V at an angle of from 5 to 85 degrees to the normal to the direction of relative motion (R) to give essentially parrallel strips.
