| titleOfInvention | Pressure sensitive recording material |
| abstract | (57) [Abstract] [PROBLEMS] To provide a pressure-sensitive recording material which has a suitable absorption for optical character reading from the visible portion to the near infrared portion and forms a colored image with good storage stability and hue. [Structure] In a pressure-sensitive recording material of a system in which a colorless or light-colored color developing agent is brought into contact with an electron-accepting color developing agent to develop a color, the following general formula is used as a color forming agent for image formation for optical character reading. A pressure-sensitive recording material containing at least one phthalide compound and at least one fluoran compound. [In the formula, R 1 and R 2 are an alkyl group having 1 to 8 carbon atoms, a cycloalkyl group having 5 to 7 carbon atoms, an alkoxyalkyl group having 3 to 7 carbon atoms, an aralkyl group, or an aryl group which may have a substituent. And R 1 and R 2 may combine to form a heterocycle. R 3 is a halogen atom, an alkyl group, An alkoxy group or an amino group having a substituent is shown. n shows 0-4. ] |
