    摘要： Antihalation layers or filter layers for photographic materials containing a combination of the following dyes: (I) Condensation products of alkoxyaldehydes with pyrazolones in which the dye molecule contains an acid group, a diffusion-preventing radical and in addition an alkoxy substituted phenyl ring, (II) tri- or pentamethine oxonoles of alkyl substituted thiobarbituric acids preferably in form of their silver salt and (III) color lakes of aurin tricarboxylic acid. Said antihalation layers or filter layers absorb predominantly in the blue and green region of the spectrum and can be decolorized as completely as possible even if a filter is processed automatically in a roll development machine with a very rapid through-put.
