ABSTRACT:
Positive-working imageable elements comprise a radiation absorbing compound and inner and outer layers on a substrate having a hydrophilic surface. The inner layer comprises a combination of two different polymeric binders one of which has an acid number of at least 30, which combination of polymers provides improved post-development bakeability (more quickly baked or cured at lower temperatures) and desired digital speed with no loss in chemical resistance.
