A photocurable relief image printing element is provided. The relief image printing element comprises at least a backing layer and at least one photocurable layer on the backing layer. The photocurable layer comprises at least one binder, at least one ethylenically unsaturated monomer, at least one photoinitiator, and an effective amount of a syndiotactic 1,2-polybutadine. The presence of the syndiotactic 1,2-polybutadiene results in a photocurable layer that exhibits minimal cold flow and good storage stability.
