PHOTOPOLYMERIC LAYERED COMPOSITE MATERIAL FOR MAKING FLEXOGRAPHIC PRINTING ELEMENTS Russian patent published in 2011 - IPC G03F7/09 

FIELD: physics.

SUBSTANCE: layered composite material contains a photopolymeric relief-forming layer (a), at least containing elastomeric binder, ethylenically unsaturated monomers and a photoinitiator, as well as other additives if necessary. Also, if necessary, the layered composite material contains a photopolymer elastomeric layer of a substrate (b), at least containing elastomeric binder, ethylenically unsaturated monomers and a photoinitiator, as well as other additives if necessary. In each case, the relief-forming layer (a) in photopolymeric state has Shore hardness A from 30 to 70°, and the elastomeric layer of the substrate (b) has Shore hardness A from 75° to Shore hardness D of 70°. The layer of the substrate (b) has Shore hardness A at least 5° higher than that of layer (a).

EFFECT: high adhesion between an adhesion layer and a photopolymeric layer.
