New Characteristic Additives designed for Imaging Toner - Fine Metallic Soaps & High-Purified Solid Esters -

Abstract

Fine metallic soap particles and high-purified solid esters are the first products in the world. These products are produced by the latest production technologies, and give various interesting features to toner. Fine metallic soap particles are thin and smooth, and have extremely narrow particle size distribution. Further, average particle size of fine metallic soap particles is controlled 0.1∼3 μm (in the case of zinc stearate or calcium stearate). These particles can uniformly coat resin particles as toner, and give high fluidity and anti-blocking characteristic. On the other hand, high-purified solid esters have 60∼85°C melting point and quite narrow melting temperature range. Accordingly, these esters give low-temperature fixing and good keeping stability for toner. Further, these esters include little impurities. So starting temperatures of decomposition are very high. Accordingly, These esters are difficult to product decomposition gas at fixing temperature of toner.
