PURPOSE:To improve yellowing properties due to the light of a background in a thermal recording material excellent in image preservability. CONSTITUTION:In a thermal recording layer containing an imino compd. and an aromatic isocyanate compd., the content of the aromatic urea compd. in the thermal recording layer is set to 20 pts.wt. or less per 100 pts.wt. of the aromatic isocyanate compd. By this constitution, yellowing properties against the light of a background are reduced. |
