    • The present invention relates to an inkjet recording element having good dye keeping properties in time, good image quality, as well as instant dryness. Said inkjet recording element comprises a porous polyester support and at least one ink-receiving layer, said ink-receiving layer comprising at least one aluminosilicate polymer obtainable by a preparation method consisting in treating an aluminum halide with an alkyl orthosilicate only having hydrolyzable functions with an aqueous alkali in the presence of silanol groups, the aluminum concentration being maintained less than 0.3 mol/l, the AI/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 ambient temperature in the presence of silanol groups for long enough to form the aluminosilicate polymer. In addition, the ink-receiving layer does not contain a binder.
    • 本发明涉及一种在时间上具有良好的染色保持性,良好的图像质量以及即时干燥性的喷墨记录元件。 所述喷墨记录元件包括多孔聚酯载体和至少一个油墨接收层,所述油墨接收层包含至少一种铝硅酸盐聚合物,该铝硅酸盐聚合物可通过制备方法获得,所述制备方法包括用仅具有可水解功能的烷基原硅烷处理卤化铝 在硅烷醇基团存在下,碱的浓度保持小于0.3mol / l,Al / Si摩尔比保持在1和3.6之间,碱/ Al摩尔比保持在2.3和3之间; 然后在室温下在硅烷醇基团存在下搅拌所得混合物足够长的时间以形成硅铝酸盐聚合物。 此外,油墨接收层不含粘合剂。
