Abstract
A thermosensitive record medium comprising a base sheet coated with a thermosensitive mixture resulting by mixing together a crystal violet lactone and a phenolic compound in a binding and dispersing agent comprising at least 5% of nonionic cellulose ether. The use of this binder improves the stability of the mixture avoiding any unusual color reaction.
