The present invention relates to a method for preparing a hybrid aluminosilicate polymer and the polymer resulting from this method. Said method consists in treating an aluminum halide with a mixture of at least one silicon alkoxide only having hydrolyzable substituents and at least one silicon alkoxide having a non-hydrolyzable substituent, with an aqueous alkali, in the presence of silanol groups, aluminum concentration being maintained at less than 0.3 mol/l, the Al/Si molar ratio being maintained between 1 and 3.6 and the alkali/Al molar ratio being maintained between 2.3 and 3; and then in stirring the resulting mixture at ambient temperature in the presence of silanol groups for long enough to form the hybrid aluminosilicate polymer.

The invention relates to an ink reservoir for ink jet printing. This reservoir includes a solid electrolyte pellet inserted in the wall of the reservoir, which conducts O2− ions when subjected to an electric current. The reservoir allows to control the internal atmosphere of the reservoir above the free surface of the ink that it contains.
摘要:
An inorganic polymeric aluminosilicate material and a method for preparing the same, are disclosed. Instead of having a fibrous structure, the material has a structure consisting of spindles with a length in the range of from 10 to 100 &mgr;m and a width in the range of from 2 to 20 &mgr;m. This polymeric aluminosilicate can be used for the production of antistatic layers.

An ink jet recording element having very good dye keeping properties in time. The recording element comprises a support and at least one ink-receiving layer, the ink-receiving layer comprising at least one hydrosoluble binder and at least one aluminosilicate polymer obtained by a preparation method consisting in treating an aluminum halide with a mixture of at least one silicon alkoxide only having hydrolyzable substituents and at least one silicon alkoxide having a non-hydrolyzable substituent, with an aqueous alkali in the presence of silanol groups, the aluminum concentration being maintained less than 0.3 mol/l, the Al/Si molar ratio being maintained between 1 and 3.6 and the alkali/Al molar ratio being maintained between 2.3 and 3; and then stirring the resulting mixture at a temperature of from 15° C. to 35° C. in the presence of silanol groups for long enough to form the hybrid aluminosilicate polymer.
摘要:
The present invention relates to a material intended for forming or printing images, comprising a support and at least one hydrophilic binder-based layer, and its manufacturing method, said method enabling the gelation process of the hydrophilic binder to be controlled. The material according to the invention is characterized in that in at least one of said hydrophilic binder-based layers, said hydrophilic binder is gelated by complexation with a complexing agent present on a heat-sensitive polymer or copolymer, that is hydrophobic at temperatures higher than its lower critical solution temperature LCST to protect the complexing agent, and water-soluble at temperatures less than its LCST to make the complexing agent accessible, the LCST of the heat-sensitive (co)polymer being higher than the setting temperature of said hydrophilic binder. The material according to the invention can be used as photographic material or as material taking aqueous ink compositions applied by the inkjet printing technique.
