Application of Light-sensitive Resin System in Preparation of Printing Plate

Abstract

Light-sensitive resin systems are recieving increased attention owing to their broad application, in particular the printing industry.
Light-sensitive resin systems for application in the preparation of printing plate are reviewed.
The system are composed from (1) a light-sensitive group can be attached to a reactive polymer substrate, (2) a light-sensitive difunctional additive can be added to a polymeric substrate.
Whether the exposed area become insoluble or soluble, the systems are ref ered to as negative or positive resists. Light-sensitive systems for negative resists are composed from diazo containing, diazide containing compositions, or poly-vinyl cinnamates, for positive resists diazo quinone containing compositions are known. Also relief imagesare was produced from photopolymerizable acrylic containing compositions.
These resists and reliefimages are produced through photodecomposition, photocrosslinking (photodimerization), or photopolymerization.
