Abstract

The invention pertains to a printing form precursor, a method of preparing a printing form from the precursor, and a process of preparing the precursor. The printing form precursor includes a photopolymerizable layer, an elastomeric layer having at least an elastomeric binder and particulate, and an actinic radiation opaque material on, adjacent, or disposed above the elastomeric layer opposite the photopolymerizable layer. The particulate is selected from specific material particles having an average diameter from 1 to 10 micron and a refractive index that is within 0.04 units of an index of refraction of the composition forming the elastomeric layer.
