A process for preparing an image on a substrate by applying a photoimageable composition on a first substrate, wherein the photoimageable composition, having a solids content from 25 to 60 weight percent, contains a partially neutralized acid-containing polymer formed from a precursor polymer having an acid number from 90 to 160 prior to neutralization and wherein 1 to 15% of acid-containing groups of the precursor polymer are neutralized with base; an ethylenically unsaturated monomer; a photoinitiator or photoinitiating system, water; 0-5% by weight a solution polymer, based on the weight of total polymer present in the composition; and 0-25% by weight of an organic solvent based on the total weight of the organic solvent and water; wherein the liquid composition is present as a stable emulsion, and wherein the liquid composition has a Brookfield viscosity, at 25 DEG C, from about 10 to about 2000 centipoise; drying the coated photoimageable composition to form a photoimageable layer on a first substrate; imagewise exposing the layer to form imaged and non-imaged areas; and developing the exposed layer having imaged and non-imaged areas to form an image on the first substrate. The exposed layer may be developed by a wash-off development process, peel-apart development process or by application of a toner which may be in the form of a dry toner or a toning film. Print out images may also be obtained. |
