Abstract
A photosensitive composition which is suitable for free radical polymerization systems initiated by ultraviolet light, particularly useful in UV-curing coating and image transfer systems such as printing plates and photoresists. Among the above mentioned applications, systems in which the photosensitive layer has no protective film to insulate it from the air shows the greatest improvement in photosensitivity.
