Pressure-sensitive copying paper
专利汇可以提供Pressure-sensitive copying paper专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain dark transcribing coloration image on ordinary paper by utilizing dual capsule where one of the coloration material or the developing material is treated as the core of the capsule and the core is wrapped by other materials. CONSTITUTION:Solvent or dispersion is treated as the core material where the coloration material and developing material are added to the nonvolatile oil such as plant oil, animal matter oil, mine oil and composite oil. In order to make a dual capsule, combining coloration material and developing material, capsuling method using in-situ method is employed. Microcapsule composed of the cell of polymer such as urea-formaldehyde polymer is utilized and the viscosity of the core material is arranged between 40-15,000cps. when applying to the supporting body as applied fluid using air-knife coater, the applied fluid is painted to the part of supporting body using ordinary carbone printer, where the applied fluid is obtained by uniformly mixing the dual capsule at the melting temperature of wax after drying the capsule by atomizing.，下面是Pressure-sensitive copying paper专利的具体信息内容。
