Abstract: PURPOSE:To obtain a beautiful purple colored free from change of color and fading by treating solid surface with an aqueous solution of gold salt, irradiating the whole face of the surface with light rays or through an image carrier and removing the gold salt on unexposed part. CONSTITUTION:Solid surface of silk fiber, cellulose fiber subjected to cationic treatment or solid material coated with gelatin is treated with an aqueous solution of a gold salt such as chloroauric acid, sodium chloroaurate or potassium tetracyanoaurate. Then the whole face of the solid surface is irradiated with light rays to seal the metal salt to the whole face. Light rays of negative image are projected to the surface by using a proper image carrier to partially form gold fine particles, the gold salt on an unexposed part is eluted and removed to provide a positive image colored in purple only on the exposed part.

Abstract: PURPOSE:To obtain a specified thiophene polymer in a neutral state and an organic semiconductor in the form a film which is excellent in heat resistance and smoothness, stable in air and useful as a display material and can be obtained without molding, by doping said polymer with an anion. CONSTITUTION:A compound of formula I, for example, synthesized by adding a Grignard reagent obtained by, for example, reacting 2-bromothiophene with metallic Mg to 2,5-dibromothiazole and condensing the mixture together with a supporting electrolyte comprising an anion-forming substance such as tetrafluoroborate, perchlorate, hexafluorophosphate, halide, SO4 or trifluoroacetate ion is electrolytically polymerized in a polar solvent such as propylene carbonate by using gold, platinum or the like as an electrode at a controlled electric quantity in an inert atmosphere. In this way, an anion-doped thiophene of repeating units of formula II (wherein R is a group of formula III, IV or V) having an electric conductivity of 10 -10 S/cm and a desired film thickness can be obtained. If desired, this polymer is converted into a thiophene polymer in a neutral state by removing the dopant by reversing the polarity.
