High-resolution flexographic printing plate and means for producing same

A recording element which is suitable for the production of high-resolution flexographic printing plates by means of digital information transmission, that can be imagined with actinic laser radiation or that is imaged, said recording element comprises or consists of the following layers arranged one above the other in the stated sequence:

• (A) a carrier film, optionally provided with an adhesive layer on the side provided with a photopolymerizable layer/relief layer,
• (B) a photopolymerizable layer/relief layer which is soluble in organic solvents and/or aqueous solvents and which is crosslinkable by actinic radiation,
• (C) optionally an actinic radiation transparent intermediate layer or an actinic radiation transparent intermediate film as a separating element, which may optionally be provided with an adhesive layer on the side provided with a photo-polymerizable layer/relief layer,
• (D) a recordable template layer comprising a monomeric diazonium compound which is photosensitive to actinic laser radiation and undergoes a change in actinic density by development or
• (Da) an imaged template layer in which the monomeric diazonium compound is destroyed by actinic laser radiation in at least an area and has an increased actinic density in at least one unexposed area due to development.
