More Information
Summary:Photocurable molding, impregnating and coating compositions based on unsaturated polyester resins containing UV sensitizers, wherein the sensitizers are acylphosphine oxide compounds of the general formula A preferred sensitizer is 2,4,6-trimethylbenzoyldiphenylphosphine oxide which is employed with or without conventional UV sensitizers, preferably benzil-dimethylketal. The compositions can be cured to give moldings and coatings.
