<P>PROBLEM TO BE SOLVED: To provide a developing sheet for pressure-sensitive copying which features rapid color developing speed, especially, early color developing speed, excellent color developing properties coupled with desensitization effect, and is manufactured by an on-machine process. <P>SOLUTION: This developing sheet for pressure-sensitive copying comprises a base and a developing layer formed on one of the main surfaces of the base. The developing layer is formed of a coating material obtained by blending an electron-acceptive coating material, a binder and a pigment. The electron-acceptive developing agent has a weight average particle diameter of 0.5 to 1.0 μm and a melting point of 100 to 160°C. In addition, the sheet is manufactured by an on machine process covering a continuous operating sequence of base making, coating material application and drying of a coating layer. <P>COPYRIGHT: (C)2007,JPO&INPIT |
