Process for the production of registration layers and their use in the preparation of flexographic printing forms.

摘要

A process which produces flexible registration layers composed of a photosensitive mixture containing
(A) at least one elastomeric binder,
(B) a mixture of (B1) at least one photopolymerizable organic compound compatible with (A) and containing at least two olefinic double bonds, and (B2) at least one mono-olefinically unsaturated photopolymerizable organic compound whose homopolymer has a glass transition temperature which is below room temperature,
(C) at least one photo initiator and also, optionally, (D) further standard auxiliaries and additives.
These registration layers are suitable for producing flexographic printing forms.
