ULTRAVIOLET-ABSORBING FIRE-PROOF AND -RESISTANT TRANSPARENT PLATE

摘要

An ultraviolet-absorbing fire-proof and -resistant transparent plate consituted of a plurality of transparent base sheets spaced in the direction of plate thickness, one or more expandable layers which lie between (or among) the base sheets and contain a heat-sensitive expanding agent, and an ultraviolet-absorbing layer which has amide linkages of an aminosilane compound and lies on at least one of the base sheets.
