Preparation of ozone resistant printing plates |
摘要 |
Process for improving ozone resistance of photosensitive flexographic relief printing plates prepared from at least 30% by weight of a block copolymer as defined, at least 1% by weight of at least one addition polymerizable ethylenically unsaturated compound, and a polymerization initiator wherein there is applied to the dry relief surface of said plates a solvent solution containing at least 1% by weight of a nickel or zinc dialkyldithiocarbamate compound where alkyl is from 1 to 4 carbon atoms. The treated plates which possess improved ozone resistance are useful for flexographic printing.
