Polyester compounds which are hardenable by ultraviolet radiation in the presence of an alpha-substituted benzoin ether
Abstract
Abstract The present invention relates to compounds which contain at least one activated carbon-carbon double bond and which can be polymerized by ultraviolet irradiation and to mixtures of such compounds to which special benzoins substituted in the Alpha position are added as photosensitizers. While the addition of known photosensitizers of this kind to the polymerizable compounds has the disadvantages that the compositions are insufficiently reactive when irradiated with ultraviolet rays and especially their stability in dark storage is quite unsatisfactory, these disadvantages are avoided by the use of Alpha -substituted benzoin ethers as photosensitizers according to the invention.
