    摘要： This invention relates to polymeric ultraviolet light stabilizers which are the esterification products of (A) phenolformaldehyde condensates, which have at least 12.5 mol % of the positions ortho to the esterifiable hydroxyl group unsubstituted, and (B) a compound capable of esterification with the phenol formaldehyde condensate which contains at least one ring of six carbon atoms characterized by having benzenoid unsaturation. Upon exposure to ultraviolet light, the exposed portion of the ester rearranges to form a polymeric compound which is a barrier to ultraviolet light.

    摘要： This invention relates to a sheet material with electrically conducting properties for use in electrographic printing wherein a water soluble conductive substance comprising at least one member of a class of polymers formed by the reaction of a 1,4dihaloalkene-2 compound and an aliphatic di(tertiary amine) is applied to the sheet material to give a weight ratio in the range of 1:1 to 500:1. This sheet material is then treated further with conventional adjuncts such as film forming resins, pigmented resins, photoconductive compositions, etc.
