Process for preparing an aqueous developable photosensitive element

A process for preparing a photosensitive element comprising:

• (a) polymerizing an elastomeric monomer as a latex dispersion in water to form an elastomeric core, wherein at least 10% of the elastomeric monomer is unpolymerized;
• (b) copolymerizing the unpolymerized elastomeric monomer with an ethylenically unsaturated monomer or oligomer having acidic functionality to form a core shell microgel binder;
• (c) removing the water;
• (d) mixing the microgel binder with (i) at least one ethylenically unsaturated monomer or oligomer, and (ii) a photoinitiator system, to form a photosensitive mixture;
• and
• (e) applying the mixture from step (d) to a support to form a layer,
• wherein step (c) can be carried out after step (b) or step (d), or simultaneously with step (d).
