NOVELTY - A moisture adsorbent comprises amorphous aluminum silicate and hygroscopic salt. The amorphous aluminum silicate has silicon/aluminum ratio of 0.7-1 and peaks of -78 ppm and -87 ppm in solid-state (29)silicon nuclear magnetic resonance spectrum.    USE - Moisture adsorbent is used for sheet-like article and filter material (both claimed) used in dehumidification process. Uses include but are not limited to desiccant air conditioner, packaging material, electric products, housing interior material, heat-exchanging component, non-flammable building material, dehumidifier, fuel cell element, automatic vending machine and heat-transfer system.    ADVANTAGE - The moisture adsorbent has improved stability and high hydrophilicity and moisture absorptivity even at high humidity conditions.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) sheet-like article, which is formed using moisture adsorbent;    (2) filter material, which is formed using moisture adsorbent;    (3) moisture-absorptive release sheet, which contains amorphous aluminum silicate and water-soluble silicate;    (4) manufacture of moisture-absorptive release sheet, which involves forming a sheet comprising amorphous aluminum silicate and water-soluble silicate, and bake-processing at 920 degrees C or less;    (5) moisture-absorptive release structure, which is formed by supporting composition containing amorphous aluminum silicate and water-soluble silicate to honeycomb-like structure;    (6) manufacture of moisture-absorptive release structure, which involves forming honeycomb-like structure supported with composition containing amorphous aluminum silicate and water-soluble silicate, and bake-processing the honeycomb-like structure at 920 degrees C or less;    (7) adsorptive sheet, which has an adsorption layer containing adsorption agent and binder and provided on sheet base material. The adsorption agent contains amorphous aluminum silicate having silicon/aluminum ratio of 0.7-1 and peaks of -78 ppm and -87 ppm by (29)Si solid-state NMR spectrum; and    (8) coating liquid, which contains adsorption agent, binder and organic solvent. The binder is organic solvent-soluble polymer.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional schematic view of moisture absorption-and-desorption testing apparatus.
