ABSTRACT:
A stabilizer, applied either as a coating over the sub-base layer of a presensitized planographic plate or blended into the sensitizer layer thereof, prevents degradation of the sensitizer enabling such plates to be stored over prolonged periods of time without loss of image quality or printing performance. The stabilizer is an aryl sulfonic acid or derivative thereof and, preferably, a haloaryl sulfonic acid or alkali metal salt thereof. In a particularly preferred presensitized plate, a p-chlorobenzene sulfonic acid coating is directly applied to a silicated anodized aluminum plate base and forms a separate layer interposed between the silicate sub-base and a water soluble diazo resin sensitizer layer.
