Abstract: PURPOSE: To enable clear white and colored discharge printing in exhibiting an excellent resist printing property without using a reducing agent by utilizing a viscous solution of a polyamide derivative having thermal reversibility as a resist agent. CONSTITUTION: A viscous aqueous solution of a polyacrylamide derivative having thermal reversibility phase transversal to hydrophilic property at a low temperature and hydrophobic property at a high temperature is prepared, the aqueous solution is printed to a natural or a synthetic fibers cloth according to a normal method and a discharge printing colored glue is overprinted (or dipped dyed) at a temperature higher than a phase transition point of the thermally reversible compound. By using the thermally reversible poste, an excellent resist printing effect is exhibited without using a reducing agent and clear white removing or colored discharge printing can be performed.

Abstract: PURPOSE:To obtain an organic semiconductor stable in air and excellent in heat resistance, film smoothness, variety of developed colors, etc., by doping a specified polymer obtained by introducing a heterocyclic group other than a thiophene group into the molecular chain of a thiophene polymer with an anion. CONSTITUTION:The purpose organic semiconductor is prepared by doping a polymer consisting of repeating units of formula I (wherein R is formula II, III or IV) with an anion (e.g., tetrafluoroborate ion or perchlorate ion). Said polymer is produced by electrolytically polymerizing a compound of formula V, VI or VII. Although the polymer obtained by the electrolytic polymerization has been doped with the anion of the supporting electrolyte used, the dopant can be removed by reversing the polarity in the electrolytic polymerization to give a polymer in a neutral state. The obtained polymer can be suitably used as an electrode material, a solar battery material or the like.
