A method is provided for the production of zinc acrylate which possesses an essentially fine constitution, permits easy pulverization into a fine powder, and, when kneaded with a rubber composition, attains uniform diffusion in a state very rarely inducing fast adhesion or formation of cluster. The fine zinc acrylate powder is obtained by a method which comprises causing acrylic acid and a higher fatty acid of 12-30 carbon atoms to react with zinc oxide in an organic solvent while continuing dispersion of the zinc oxide in the organic solvent in the presence of an anionic surfactant.

Method for production of zinc acrylate

An apparatus for thermal development of thermal fixation of a flexible sheet of photosensitive material. The apparatus includes a heating roller provided with a heating lamp inside said heating roller, a plurality of conveyance rollers disposed in pressure contact with the heating roller, so that when the sheet is put in between the heating roller and the conveyance rollers, the sheet is heated to undergo the processing, and guides, provided in pressure contact with the peripheral surface of the heating roller, for holding the sheet against the peripheral surface of the heating roller.
