A substantially light-insensitive monosheet thermographic recording
material comprising a support and on one side of the support a
thermosensitive element, the thermosensitive element comprising at least
one substantially light-insensitive silver salt of a carboxylic acid, at
least one reducing agent therefor in thermal working relationship
therewith and at least one binder, the at least one binder comprising at
least one first polymer consisting of vinyl aceto-acetal monomer units
and optionally monomer units selected from the group consisting of vinyl
alcohol, vinyl acetate and itaconic acid monomer units, wherein the
weight ratio of the at least one binder to the light-insensitive silver
salt(s) of a carboxylic acid in the thermosensitive element is greater
than 1.6; and the at least one binder optionally contains less than 40%
by weight of a second polymer consisting of vinyl butyral monomer units
and optionally vinyl alcohol and/or vinyl acetate monomer units.
