摘要: A thermosensitive recording material having a thermosensitive color forming layer containing a specific dispersing agent and binder mixture showing a softening point of at least 70.degree. C. can minimize occurrence of head stain at a thermal head in thermosensitive recording. The combination of sulfonic acid-containing polyvinyl alcohol and polyacrylamide or acrylamide-acrylonitrile copolymer is preferable.
