  • Heat-sensitive recording materials and recording process of using the same
    Patent number: 4165741
    Abstract: Heat-sensitive recording materials having a recording layer comprising a soluble heat-sensitive organic high molecular weight compound which is folded to show a granular state on a support, and a recording process for obtaining images which comprises imagewise applying heat to the recording layer to insolubilize the high molecular weight compound and removing by dissolving the portion of the recording layer where the high molecular weight compound is not insolubilized.
