| titleOfInvention | Overhead projectior sheet and record formation |
| abstract | PURPOSE: To desensitize an ink or toner supply part to form a uniform and sharp negative recording by a method wherein an ink or toner containing a desensitizing substance is supplied to a synthetic resin sheet containing thereon or therein a reaction product of a chromogenic substance in a color forming state. n CONSTITUTION: An over head projector sheet having a uniform and sharp negative recording can be obtained by combining a chromogenic substance with a desensitizing substance (a decoloring component) for the substance. As the chromogenic substance for use, the combination of an electron donative color former and an electron accepting developer, the combination of a metal salt and a coordination compound, and the like can be used. The composition ratio of the chromogenic substance is determined to range 0.01-100 moles of the electron accepting developer per 1 mole of the electron donative color former, or 0.01-100 moles of the coordination compound per 1 mole of the metal salt. As the desensitizing substance for use, triocthylphosphate or the like can be used if the electron donative color former and the electron accepting developer are combined as the chromogenic substance, and an organic compound having aminocarboxylic acid groups or the like can be used of the metal salt and the coordination compound are combined. n COPYRIGHT: (C)1990,JPO&Japio |
