Abstract
Procedure for protecting organic materials that are deteriorated by ultraviolet radiation from the action of ultraviolet radiation, characterized by incorporating bis-oxalic acid amidoesters of the materials to be protected, or applied to the surface of these materials. a filter layer containing bis-oxalic acid amidoesters corresponding to the formula A1-O-CO-CO-NH-W1-NH-CO-CO-O-R1 where A1 and B1 are the same or different and represent an alkyl, alkenyl, cycloalkyl, aralkyl or aryl group, which groups may eventually contain still other substituents and must not shift the absorption maximum of these compounds to values of more than 370 millimeters, and W1 means a phenylene, diphenylene or naphthylenic radical or a radical **(See formula)** in which case the phenylene groups of these radicals can bear one or two Z1 substituents with the meaning of an alkyl or alkoxylic group with 1 to 4 carbon atoms, of a halogen atom or of a SO2H group, m means the numbers 0, 1 or 2 and X1 represents an alkylene group with 1 to 4 carbon atoms or a bridging member -O-, -S-, (see formula) or -SO2-.
