    • The present invention relates to an inkjet recording element having good dye keeping properties in time and good image quality. Said inkjet recording element comprises a porous polyester support and at least one ink-receiving layer, said ink-receiving layer comprising at least one hydrosoluble binder and at least one aluminosilicate polymer obtainable 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/A 1 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 hybrid aluminosilicate polymer.
    • 本发明涉及一种在时间上具有良好的染色保持性和良好的图像质量的喷墨记录元件。 所述喷墨记录元件包括多孔聚酯载体和至少一个油墨接受层,所述油墨接收层包含至少一种水溶性粘合剂和至少一种铝硅酸盐聚合物,所述铝硅酸盐聚合物可通过制备方法获得,所述制备方法包括:将卤化铝与 至少一个仅具有可水解取代基的硅烷氧化物和至少一种具有不可水解取代基的硅烷氧化物,在硅烷醇基团存在下,碱水溶液中,铝浓度保持在0.3mol / l以下,Al / Si摩尔 保持在1和3.6之间,碱/ A 1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时间以形成混合硅铝酸盐聚合物。
