  • Quaternary Nitrogen Compound for Use as a Latent Catalyst in Curable Compositions
    Publication number: 20200048411
    Abstract: The present application relates to a quaternary nitrogen compound comprising a nitrogen heterocycle wherein: at least one polymeric substituent is bound to a ring atom of said heterocycle; and, an aromatic photoremovable group (PRG) is directly bound to a quaternary nitrogen ring atom of said heterocycle, the release of said aromatic photoremovable group under UV irradiation yielding a tertiary amine. The application further relates to the use of said quaternary nitrogen compound as a latent catalyst in a curable composition, the curing of which may be catalyzed or co-catalyzed by tertiary amines.
