Abstract
The performance of phosphor screens can be improved by coating the phosphor dispersion/mixture onto a substrate while the dispersion/mixture contains less than 5% by weight of polymerizable components with a molecular weight less than 300, preferably with less than 5% by weight of polymerizable components having molecular weights less than 500. The polymerizable composition should be photopolymerizable, and other components within the coating to be photohardened which have molecular weights below 300 or 500 should likewise be kept to less than 5% by weight of the composition.
