Title: Flexographic relief printing plate treatment to give tack-free surface - using bromine in plate based on styrene!-isoprene! block copolymer
Inventor: TAUBITZ CHRISTOF DIPL CHEM DR
IPC: G03F7/40
Filed: 1978-05-29
Abstract: Prodn. of tack-free surfaces on flexographic relief printing plates is effected by treating the tacky surface with Br2, which can be in the form of an (aq.) soln. or a Br-releasing complex cpd. The reliefs are made by selective exposure with actinic light of a polymer monomer mixt. contg. a styrene-isoprene block copolymer with >=2 blocks of 30-95 wt.% isoprene with a mol.wt. of 2000-100,000 and of 5-70 wt.% styrene with a mol. wt. of 20,000-1,200,000, followed by removal of the unexposed areas. The plates are uniformly tack-free and do not become tacky again, even after use for large editions (e.g. over 1,000,000). The characteristic yellow colour of the Br2 solns. allows their concn. and hence effectiveness to be assessed, even in yellow safety light, and the spent solns. can easily be rendered harmless by treatment with Na2S2O3.
