Disclosed is a filler for a heat-sensitive recording paper comprising finely divided amorphous silica having a BET specific surface area of 10 to 100 m.sup.2 /g and a bulk density of 0.14 to 0.30 g/cc, said finely divided amorphous silica having such a secondary particle size distribution that secondary particles having a size smaller than 4 microns, as measured by the centrifugal precipitation method, occupy at least 90% by weight of the total particles. This filler is excellent in the effects of preventing the background coloration, improving the lubricating property, preventing the adhesion of scum and improving the image density.

A multilayer glass structure constructed by joining the edge portions of a plurality of glass sheets by a sealant through spacers having an adsorbent filled therein. According to this invention, the adsorbent comprises a combination of a granular zeolite composed of a core of a synthetic zeolite/clay binder mixture containing the synthetic zeolite in an amount larger than its average content in the granular zeolite and a shell of a synthetic zeolite/clay binder mixture containing the clay in an amount larger than its average content in the granular zeolite, with granular activated carbon having on its surface 1 to 20% by weight, based on the activated carbon, of a coating of a synthetic resin latex. The adsorbent can effectively adsorb water vapor and the vapor of an organic solvent evaporated from the sealant, and prevent dew deposition on the glass surface. Moreover, it does not yield dust even when the glass structure is handled under severe conditions.

Disclosed is an abrasion-resistant granular zeolite formed from a mixture of a synthetic zeolite and a clay binder, said granular zeolite comprising a core composed of a synthetic zeolite clay binder mixture containing the synthetic zeolite at a content higher than the average synthetic zeolite content in the granular zeolite and a shell composed of a synthetic zeolite-clay binder mixture containing the clay binder at a content higher than the average clay binder content in the granular zeolite. This granular zeolite is excellent in both the zeolitic characteristics such as adsorbability and ion exchange capacity and the mechanical strength characteristics such as abrasion resistance and compression strength.
