Thermoplastic elastomer compositions

A photosensitive flexographic printing element for the production of flexographic printing plates by digital imaging by means of lasers which has an IR-ablative layer with a polyether-polyurethane as binder. A process for the production of flexographic printing plates using an element of this type.

Photosensitive flexographic printing element having an IR-ablative layer comprising polyether-polyurethanes

Photosensitive printing element for preparing flexographic printing plates via computer-to-plate technology with a support, a photopolymerizable layer and an IR-ablatable layer substantially opaque to actinic radiation which comprises at least one heat-combustible polymeric binder, at least one IR-absorbing material and at least one aliphatic diester, and a process for making a flexographic printing plate using such an element.

Flexographic printing element comprising an IR-ablatable layer with improved sensitivity

A process for the production of a photosensitive recording material for producing relief printing plates is described, in which a photosensitive layer is laminated with a composite element comprising a protective cover sheet, a release layer and, if required, a further layer, wherein the surface of the uppermost layer of the composite element or the surface of the photosensitive layer is subjected to a corona treatment immediately before contact. As a result of the corona treatment, the adhesion of the applied layer is substantially increased.

Production of a photosensitive recording material

A multilayer element comprising a substrate, an intermediate layer and a photopolymerizable or photocrosslinkable layer in the stated order is used for producing printing or relief plates. The intermediate layer contains a copolymer of a monomer (A) of the formula (I) or (II) and a copolymerizable monomer (B) ##STR1## where R.sup.1 is vinyl, propen-2-yl, 1-buten-2-yl or styryl or a radical R.sup.2 --O--CO--CH.dbd.CH--, R.sup.2 is an alkyl, aryl, aralkyl or cycloalkyl radical of up to 10 carbon atoms, R.sup.3 is H, methyl or ethyl and n is from zero to 5. The intermediate layer in the multilayer element has improved adhesion in the laminate. It is initially nontacky and does not become tacky until after the application of the photopolymerizable layer, as a result of the interaction with said layer. The improved adhesion in the laminate is retained even after storage and repeated use of the finished printing plates.
