Abstract
The fire-protection glazing includes at least two glass panes, between which a transparent layer of a fire-protection layer is arranged, wherein the fire-protection layer includes a hydrogel. The educts of the fire-protection layer include water-soluble, non-toxic monofunctional monomers in an acid environment as well as at least one bifunctional or polyfunctional monomer and, as the case may be, an initiator, in an aqueous salt solution or in an aqueous salt dispersion. The monofunctional and the bifunctional or polyfunctional monomers are not toxic, not carcinogenic and not mutagenic.
