Abstract
(EN)
New compounds of formula (I) are described, wherein n is > 1; X is O or NR4; L is a n-valent linking group defined in claim 1 and R1 is H, halogen, C1-C25-alkyl, C3-C25-alkenyl, unsubstituted or by C1-C4-alkyl substituted C5-C8-cycloalkyl; R2 and R3 independently of each other are C1-C4alkyl, or together with the carbon atom they are bonded to, form a carbocyclic C5-C7 ring, especially C5-C7cycloalkylene; and m is 1-20, especially 2-4. Compounds of formula (I) are active as Dox-scavengers in color photographic material.
(FR)
L'invention concerne de nouveaux composés représentés par la formule (I) dans laquelle: n désigne 1; X désigne O ou NR4; L désigne un groupe de liaison n-valent défini dans la revendication 1; R1 désigne H, un halogène, un alkyle en C1-C25, un alcényle en C3-C25, un cycloalkyle en C5-C8 non substitué ou substitué par un alkyle en C1-C4; R2 et R3 désignent indépendamment un alkyle en C1-C4, ou pris avec l'atome de carbone auquel ils sont liés, forment un cycle en C5-C7 carbocyclique, en particulier un cycloalkylène en C5-C7; et m est compris entre 1 et 20, et notamment entre 2 et 4. Les composés représentés par la formule (I) sont actifs comme capteurs de révélateurs oxydés dans une matière photographique en couleur.
