Provided are 4-(alkoxyhydroxy)styryl triazine photoinitiator compounds having the formula: ##STR1## wherein n is 3 or 4, as well as photopolymerizable compositions and photographic elements containing such photoinitiator compounds. These photoinitiator compounds improve the reproduction quality of photographic elements such as lithographic printing plates since the photosensitive compositions in which they are incorporated are resistant to surface blooming.
