Patent

CA 2000051

The invention describes a process for stabilizing a leuco-dye solution in an organic solvent against oxidation in air. In the process, a compound containing at least one 2,2,6,6- tetraalkylpiperidine, 2,2-dialkylpiperidine-6- spiro-cycloalkane or piperidine-2,6-dispiro- cycloalkane grouping is added to the solution. The process is, in particular, used for stabilizing photoresist solutions which, apart from the leuco dye, contain polymerizable compounds and photoinitiators, especially radiation-sensitive trihalomethyl compounds.

a présente divulgation décrit un procédé permettant de stabiliser une solution de leuco-colorant dans un solvant organique contre l'oxydation en présence d'air. Ce procédé prévoit l'addition à la solution d'un composé renfermant au moins un groupement 2,2,6,6-tétraalkylpipéridine, 2,2-dialkylpipéridine-6-spiro-cycloalcane ou pipéridine-2,6-dispiro-cycloalcane. Le procédé est utilisé, notamment, pour stabiliser les solutions de résine photosensible qui, outre le leuco-colorant, renferment des composés polymérisables et des photoamorceurs, en particulier des composés trihalométhylés radiosensibles.
