The present invention relates to a radically polymerizable composition comprising a hydroxylamine ester used to manufacture color filters. The invention further relates to novel hydroxylamine esters. The invention further relates to the use of hydroxylamine esters in all liquid crystal display components requiring post-baking. The present invention relates to a radically polymerizable composition comprising: (a) at least one alkaline developable resin; (b) at least one acrylate monomer; (c) at least a photoinitiator; (d) at least one hydroxylamine ester compound of formula (I) wherein Ra represents an acyl radical; one of Rb and Rc represents hydrogen and the other one represents a substituent; or Rb and Rc both represent hydrogen or identical or different substituents; or Rb and Rc together represent oxygen; or Rb and Rc together form a ring; R1-R4 each represent C1-C6 alkyl; and R5 and R6 each represent independently of one another hydrogen, C1-C6 alkyl or C6-C10 aryl; or R5 and R6 together represent oxygen.
摘要:
The invention relates to a process for the preparation of secondary nitroxide radicals from their corresponding secondary amines by oxidation with an organic peracid, comprising the steps a) adding to a reaction vessel a secondary amine, optionally together with an organic solvent and in one batch a base selected from the group consisting of alkali metal, alkaline earth metal or ammonium bicarbonates and alkaline earth metal or ammonium carbonates or mixtures thereof in the form of a solid together with water or as an aqueous slurry; b) dosing a peracid under stirring to the reaction mixture in an amount of 1.0 to 2.5 mol per mol of secondary amine; and c) isolating the organic phase.
摘要:
Organic materials which possess outstanding stability to oxidative, thermal or light-induced degradation comprise as stabilizers at least one compound of the formula (I) wherein the general symbols are as defined in claim 1. The compounds of formula I are especially useful as stabilizers for protecting polymers and lubricants against oxidative, thermal or light-induced degradation and as scavengers for oxidized developer in color photographic material.
