Zusammenfassung:A heat-sensitive recording material having i) a carrier substrate and ii) a heat-sensitive recording layer. The heat-sensitive recording layer contains a color former and a color developer mixture and the color developer mixture contains a) N/-[2-(3-phenylureido)phenyl]benzole sulfonamide (compound of formula (I)). The compound of formula (I) is present in a crystalline form, which has an absorption band in the IR spectrum at 3401±20 cm−1, and b) N-(4-methylphenylsulfonyl)-N-(3-(4-methylphenylsulfonyloxy)phenyl)urea (compound of formula (II)).
