Disclosed are a novel electron-accepting compound which is a benzenesulfonamide
derivative having a specific structure, a heat-sensitive recording material having
a heat-sensitive recording layer containing the above electron-accepting compound,
a heat-sensitive recording material having a heat-sensitive recording layer containing
at least two specific benzenesulfonamide derivatives, a heat-sensitive recording
material having a heat-sensitive recording layer containing a benzenesulfonamide
derivative and a diphenylsulfone derivatives a heat-sensitive recording material
having a heat-sensitive recording layer containing a specific benzenesulfonamide
derivative and an ultraviolet absorbent or an aromatic isocyanate compound, and
a heat-sensitive recording material having a substrate containing a recycled paper
pulp or a non-wood pulp.
These heat-sensitive recording materials are excellent in thermal response,
retainability of ground/recorded image, saturation density and retainability of
an image portion against light.
