Photopolymerizable flexographic printing elements for printing with uv inks

A photomerizable flexographic printing element for producing flexographic printing forms for printing with UV inks, which comprises at least

• A) a dimensionally stable support and
• B) a photopolymerizable, relief-forming layer comprising at least
• 1) from 40 to 90% by weight of a thermoplastic-elastomeric block copolymer comprising at least one block which consists essentially of alkenylaromatics and at least one block which consists essentially of 1,3-dienes,
• 2) from 1 to 20% by weight of ethylenically unsaturated monomers,
• 3) from 0.1 to 5% by weight of photoinitiator and
• 4) from 1 to 40% by weight of plasticizer,
• where the amounts are in each case based on the total amount of all components of the photopolymerizable layer, and
• wherein at least one of the plasticizers is from 1 to 40% by weight of at least one cyclohexanepolycarboxylic ester of the general formula R1-(COOR2)n where
• n is 2, 3 or 4,
• R1 represents an n-valent cyclohexane radical
• R2 represents, independently of one another, a linear, branched or cyclic, aliphatic hydrocarbon radical having from 3 to 20 carbon atoms.
