Abstract: The invention relates to a single-use detector of aromatic compounds, with:—a first part (20) comprising a light conversion layer (26), and a photosensitive layer (28) in one piece with the light conversion layer, to be capable of being exposed by exposure light (54) capable of being produced by the light conversion layer in response to excitation light (50), the light conversion layer containing an imprinted polymer precursor (32), capable of combining with a target aromatic compound to form a dye (34) that converts the excitation light into exposure light in a wavelength domain different from that of the exposure light and,—a second part (40) of developer, capable of being applied temporarily to the photosensitive layer (28) of the first part (20) to demonstrate a possible exposure of the photosensitive layer. Application to the detection of explosives.

Abstract: The present invention relates to a method for improving the ozone stability of an inkjet recording element. The present invention consists in using at least one alkyl sulfonic acid or one of its alkyl sulfonate salts in an inkjet recording element, said element comprising a support and at least one ink-receiving layer comprising at least one hydrosoluble binder and inorganic particles, for improving the ozone stability of said element. Preferably, the alkyl group is linear and comprises 3 to 8 carbon atoms.

Abstract: The present invention relates to a method for improving the ozone stability of an inkjet recording element. The present invention consists in using at least one sulfonic polystyrene or one of its sulfonate salts in an inkjet recording element, said element comprising a support and at least one ink-receiving layer including at least one hydrosoluble binder and inorganic fillers, for improving the ozone stability of said element.
