Abstract
A process for producing a cigarette paper exhibiting a low ignition propensity, includes applying a first aqueous solution containing divalent cations to a base wrapping paper on a whole of its one surface, and applying a second aqueous solution containing a water-soluble gellable substance capable of gelling under the action of the divalent cations to at least a part of the surface of the base wrapping paper having the first aqueous solution applied thereto to thereby cause the gellable substance to gel and thus form a combustion-inhibiting substance consisting of the gel.
