Abstract

PURPOSE:To obtain a thermosensitized recording material excellent in waterproof quality and fitted for facsimile, etc. by adding an isocyanate compound to the combination of polyvinyl alcohol, starch oxide and etherificated starch as a binder. CONSTITUTION:To the leuco dye as a color former (A) and a phenolic compound as a color developer (B), polyvinyl alcohol (preferably of 300-2,500 in the polymerization degree and 80-100mol% in the saponification degree), starch oxide and/ or etherificated starch (a), as well as an isocyanate compound (containing two or more isocyanate radical in one molecule, such as trirange isocyanate) (b), preferably of 10-150wt% are added as binders (C), thereby the aimed material being obtained. In addition, toluene is best fitted as a solvent to be used when the ingredient (b) is added, and it is preferable that the dissolution is performed by adding 50- 300wt% of the ingredient (b) to the solvent.
