Abstract
A process is described for eliminating or substantially reducing the surface tack on relief printing plates and the like articles fabricated from radiation-sensitive polymerizable resins, particularly photopolymerizable resin compositions. The process comprises immersing the article, after curing, in an aqueous solution or dispersion comprising a water-soluble or water dispersible ethylenically unsaturated monomer (acrylic, methacrylic acids and derivatives thereof preferred) and optionally a photoinitiator and exposing the immersed plate to actinic radiation.
Claims23
A method of removing tack from the surface of a cured radiation-sensitive polymerizable resin composition which comprises the steps of immersing said composition in an aqueous solution comprising a water-dispersible polymerizable ethylenically unsaturated monomer and exposing said composition, while immersed in said solution, to actinic radiation.
A method of removing surface tack from a relief printing plate which has been fabricated from a photosensitive polymeric composition, said method comprising the steps of
- immersing said plate in an aqueous solution comprising a water-dispersible polymerizable ethylenically unsaturated monomer and a photoinitiator;
- and
- exposing said plate, while immersed in said aqueous solution, to actinic radiation.
