摘要： The novel transparent polyolefin or polyamide article disclosed is stabilized against the effects of light, oxygen, heat and agressive chemicals by addition of 0.005-0.30% by weight the polymeric substrate of a hydroxyphenyl triazine UV absorber, and is characterized by its thickness between 1 and 500 μm. Preferred polyolefin articles thus stabilized are agricultural films containing as further stabilizer a sterically hindered amine. The novel compositions act as selective UV filter especially useful in agriculture.

摘要： A color photographic material is described containing a compound of formula (I) wherein, if n=1, R 1 is, inter alia, a radical of formula (II), and, if n=2, R 1 is unsubstituted or C 1 -C 4 alkyl- or hydroxy-substituted phenylene or naphthylene; or -R 12 -X-R 13 -, and other residues are as defined in claim 1. The compound of formula (I) is effective as scavenger of the oxidized form of the developer (Dox scavenger), especially when contained in an interlayer between light sensitive layers. Selected compounds of this class can also be used as additives, for example as dye stabilizer, in color photographic materials, or as an antioxidant for organic materials.

摘要： Disclosed is a process for preventing migration of the oxidized developer in a colour photographic material from one colour sensitive layer to another by incorporating a compound of Formula (I) into the material. wherein, if n = 1, R 1 is, inter alia, a radical of formula II and, if n = 2, R 1 is unsubstituted or C 1 -C 4 alkyl- or hydroxy-substituted phenylene or naphthylene; or -R 12 -X-R 13 - , and other residues are as defined in claim 1. The compound of the formula I is acting as a scavenger of the oxidised form of the developer (Dox scavenger) and is preferably contained in an interlayer between light sensitive layers. Selected compounds of this class can also be used as additives, for example as dye stabilizer, in colour photographic materials, or as an antioxidant organic materials. Also disclosed is a digital recording material containing a compound of formula (IV) (p. 179). Also disclosed are compounds of formula (IV) (p. 179) as additives in a digital recording material. Also disclosed are compounds of formula (V) or (VI) (p. 181), used of compounds (V) or (VI) as a stabilizer for organic material against deterioration by light, oxygen and/or heat and also a process for stabilizing an organic material against deterioration by light, oxygen and/or heat by incorporating a compound (V) or (VI) into the organic material.
