摘要
A recording material consisting of a base with a ceramic coating and a light-sensitive layer, in which the ceramic layer comprises a silicate compound and aluminum oxide with at least 99.6 wt.% Al and the ceramic layer is bonded to the base by the silicate compound acting as binder. An Independent claim is also included for a process for the production of this material, in which an aqueous dispersion of aluminum oxide and a silicate compound, alone or together with titanium and/or silicon dioxide, is applied to the base by means of a flow device, a roller or a doctor blade and then dried for 50-80 seconds at 150-220 deg C.
