Abrégé
(EN)
A negative-working lithographic printing plate precursor have an outermost imageable layer that includes an oxygen scavenger and shelf-life stabilizer that is represented by either Structure (I) or Structure (II) below: wherein Ar is a phenylene or naphthylene group, R1 and R2 are independently alkyl, alkenyl, alkynyl, phenyl, phenoxy, -R5OH, -CH2-C(=O)-R3, or -CH2-Q=O)O-R4 groups, R3 is hydrogen or an alkyl or phenyl group, R4 is an alkyl or phenyl group, R5 is an alkylene group, R6 and R7 are independently hydrogen or an alkyl, -R5OH, -R5C=O)-R8, or -R5C=O)OR9 group, R8 is hydrogen or an alkyl group, and R9 is an alkyl group, provided that the oxygen scavenger has no more than one carboxyl group.

Le précurseur de plaque d'impression lithographique négative ci-décrit a une couche ultrapériphérique imageable qui comprend un intercepteur d'oxygène et un stabilisant pour augmenter sa durée de vie et est représenté soit par la Structure (I), soit par la Structure (II) ci-dessous : dans ces Structures, Ar est un groupe phénylène ou naphtylène, R1 et R2 sont indépendamment des groupes alkyle, alcényle, alcynyle, phényle, phénoxy, -R5OH, -CH2-C(=O)-R3, ou -CH2-Q=O)O-R4, R3 est un atome d'hydrogène ou un groupe alkyle ou phényle, R4 est un groupe alkyle ou phényle, R5 est un groupe alkylène, R6 et R7 sont indépendamment un atome d'hydrogène ou un groupe alkyle, -R5OH, -R5C=O)-R8, ou -R5C=O)OR9, R8 est un atome d'hydrogène ou un groupe alkyle, et R9 est un groupe alkyle, à condition que l'intercepteur d'oxygène ne contienne pas plus d'un groupe carboxyle.
