Definitions

  • the heat-sensitive material of the present invention is produced by applying the coating composition forming the color developing layer to a base material such as paper, synthetic paper, film, etc.
  • the heat-sensitive recording material of the present invention is stable against solvents such as alcohol, etc. in the background.
  • Both the organic acid iron salt and the polyvalent phenol derivative which can be used in the present invention contain an alkyl group having at least 18 carbon atoms, so that their diffusion rate and solubility in the solvents are very small.
  • the cause of the superior oil resistance is based on an irreversible color development reaction between the organic iron salt and the polyvalent phenol derivative. That is, once this color development reaction occurs, a very stable complex is formed, the binding of which is not released when the hair oil, oil materials, etc. are attached. Therefore, the color image is stable.
  • This coating composition was applied in an amount of 6.0 g / m 2 to a base paper with a weight of 50 g / m2, dried and calendered to set a smoothness of 200-600 seconds. A heat sensitive recording material was obtained.
  • This coating composition was applied, dried and calendered in the same manner as in Example 1. A heat sensitive recording material was obtained.
  • This coating composition was applied, dried and calendered in the same manner as in Example 1. A heat sensitive recording material was obtained.
  • This coating composition was applied, dried and calendered in the same manner as in Example 1. A heat sensitive recording material was obtained.
  • the optical density of the non-recorded part is determined using a Macbeth density meter.
  • the residual image density is calculated from the following formula:
