Abstract (en)
[origin: EP0325231A2] The heat-sensitive recording material contains a fluorane leuco dye and a divinyl compound and, if desired, a fluorene leuco dye in the colour development layer, in which a basic colourless or weakly coloured chromogenic dye and an organic colour developer are used. The recording material in accordance with the invention has superior optical readability in the near ultra-red region, improved thermal responsiveness and improved resistance to light, oils and climatic influences.
