PHOTOSENSITIVE COMPOSITIONS AND ELEMENTS FOR FLEXOGRAPHIC PRINTING

摘要

The invention relates to the use of effective amounts of UV absorbers in a thermoplastic, elastomeric, composition layer of a photosensitive printing element to produce enhanced exposure latitude, as well as a method of producing a printing plate with the printing element. The UV absorbers most likely act as internal scavengers of scattered UV light and thereby enhance the exposure latitude of the printing element. The invention also relates to the photosensitive composition of the element.
