Stabile flüssige Zusammensetzungen zur Verwendung als Photopromotoren für die Polymerisation, ihre Herstellung und Verwendung

摘要

The present invention refers to new 1-phenylindan carbonyl derivatives based stable liquid compositions suitable for use as photo-promoters for photo-polymerizing compounds or mixtures of compounds containing ethylene double bonds, and their preparation and use. These compositions are highly stable to crystallization, and are thus suitable for storage and marketing.
