摘要： PURPOSE:To provide an image forming method capable of forming a pattern even with a weaker white light by making a soluble conjugate polymer film on a base plate, and then irradiating the polymer film with the light in a solvent gas. CONSTITUTION:An image forming method comprises forming a soluble conjugate polymer film on a base plate, then irradiating the film formed on the base plate with white light in a solvent gas, thereby making a light irradiation part insoluble, and, as occasion demands, solving and removing the non-irradiation part with the solvent to which the soluble conjugate polymer is soluble. As the soluble conjugate polymer, polyalkyl thiophene, polyalkyl pyrrole, and polyalkyl aniline are used, and as the solvent gas, hydrocarbon halide, ethers, esters, and aromatic hydrocarbons are used.

摘要： PURPOSE:To provide the polychromatic picture forming method, which generates colors in different color tones by printings of many times, with regard to the polychromatic heat-sensitive recording material, whose manufacturing process is simple, and which has excellent resolution and dot reproducibility and excellent picture preserving property. CONSTITUTION:A heat-sensitive recording material has a heat-sensitive coloring layer, whose main components are aromatic isocyanate compound and imino compound, on a supporting body. The absorbing wavelength band of the hue, which is colored when the imino compound is singly heated, is at least 600nm or more in the imino compound. The absorbing wavelength band of the hue, which is colored by mixed heating of the aromatic isocyanate compound together with the imino compound, is less than 600nm in polychromatic heat recording material, i.e., the aromatic isocyanate compound. Different heat energies are applied by printings of many times using the polychromatic heat- sensitive recording material. Thus, the polychromatic picture image forming method for forming different hues on the same surface is obtained.

This thin film is used without being dissolved and is used as a planographic printing plate. Polyalkyl thiophene is preferably used as the soluble conjugation system polymer and the more specific examples thereof include poly-3-propyl thiophene, poly-3-hexyl thiophene, etc. The images having the large area are easily formed in this way.
