The material comprises a support and at least one ink-receiving layer, wherein the ink-receiving layer comprises at least one carrageenan and at least one polymer comprising hydroxyl groups. Preferably, the carrageenan is selected from among the group comprising the ?-carrageenans, the ?-carrageenans or a combination of these compounds.

Abstract: The present invention relates to a new coating method of a material intended for inkjet printing enabling high coating speeds while reducing or eliminating coating faults. The coating method of a material intended for forming images by inkjet printing comprises heating a composition intended to form the ink-receiving layer, the composition comprising at least one polysaccharide, polyvinyl alcohol, guar gum and inorganic particles having neutral or positive surface charge; treating a support by corona discharge; coating the composition directly on the treated support, using a coating machine in which the support runs; cooling the resulting coated, treated support to obtain the thermoreversible gelation of the composition; and drying the coated, treated support.

Abstract: The present invention relates to an image receiver element comprising a support having on at least one surface thereof a porous absorbent coating layer comprising an inorganic colloidal particulate material, having a negatively charged surface, in a binder matrix, wherein the binder matrix comprises a hydrophilic gelator, a fluorinated compound, and at least one polymer comprising hydroxyl groups. The present invention also relates to a receiver for inkjet printing comprising a support having on at least one surface thereof a porous absorbent coating comprising a colloidal particulate material, having a negatively charged surface, in a binder matrix, wherein the binder matrix comprises a hydrophilic gelator, guar gum, a fluorinated compound, and polyvinyl alcohol. Carrageenan is the most preferred thermoreversible hydrophilic gelator.

Abstract: A tire tread including a tread pattern formed by a plurality of motifs in relief defined by grooves oriented in the transverse direction and in the longitudinal direction of the tread, each of these motifs including a contact face and lateral faces, a plurality of these motifs in relief being connected two by two by at least two rubber connecting elements molded during the molding of the tread. These connecting elements define, with the opposing walls of the motifs in relief to which they are connected, a cavity which closes in contact with the roadway to trap and compress a volume of air once the wear of the tread reaches an appropriate level of wear. For each cavity thus formed at least one rubber element defining the cavity includes at least one orifice which passes completely through said rubber element to cause the volume of the cavity to communicate with a groove.

Abstract: The present invention relates to a method for processing a color reversal photographic film that enables the amount of silver and tin (II) ions present in the washing water to be reduced, in order to obtain effluents that can be discharged to the drains and satisfy the regulations in force. The method according to the invention comprises the mixing with stirring of the washing water with a composite material comprising a polymer matrix in the form of an imogolite gel in fiber form comprising at least, on the fiber surface, an organic radical having an —SH function or an —S(—CH2)n—S— radical, with n between 0 and 4; the settling of said mixture, and the recovery of a supernatant having greatly reduced quantities of silver and tin (II) ions, enabling direct discharge to the drains.

Abstract: A method and device for opening a drink can provided with a frangible obturator which can be pushed back inside the can using a tongue that is fixed in a horizontal position in the middle of the lid by means of a rivet on which the tongue can pivot as a lever to produce an opening which is later closed by a movable case that is adapted on the tongue which is pivoted around the river in order to move onto the opening.

Abstract: The present invention concerns a separative membrane, as well as a separation device containing this membrane, and a method for using this device. The membrane of the present invention comprises a support, the hydrophobicity of one of whose faces has been modified, the opposite face having an active layer comprising an inorganic hydrogel material and an ion carrier. This membrane has improved selectivity.

Abstract: The invention concerns a cap (8) for closing a container such as a drink can opened (6) by a breakable seal (5) by means of a pull strip (7) on the lid, the said cap (8) being removably mounted on or around the said pull strip (7) to constitute a movable tab pivoting about the rivet (9) on the lid (4) to be clipped on the peripheral lip (12) crimping the lid (4) on the body (1) of the container. It is characterised in that the clipping means comprise two resilient linking tabs (13, 14) symmetrically arranged in the median horizontal plane P of the cap (8) on either side of the longitudinal axis of symmetry S to form a space (15) in which a lug (16) extends from a horizontal strip (17) holding together the two release tabs (13, 14). The invention also concerns the use of the cap (8) as an advertising vector or an element of a game.

Abstract: The present invention concerns a method for modifying the transfer characteristics of a porous organic or inorganic membrane, in whicha) on the said membrane, at least one layer is formed by applying at least one homogeneous solution obtained by mixing one or more rare-earth or alkaline-earth fluoroalkoxides in an anhydrous organic solvent at room temperature and in an inert atmosphere,b) hydrolysis is effected by placing the coating formed at a) in contact with a quantity of water at least equal to the stoichiometric quantity required to hydrolyse the fluoroalkoxides,c) the membrane is rinsed with water to eliminate the soluble salts formed. The membranes thus modified are useful for the regeneration of photographic solutions, in particular black and white developers, or for the separation of organic compounds from aqueous effluents.
