摘要: 阴图PS版感光层主要是由成膜树脂和感光树脂组成.感光树脂一般是二苯胺或取代二苯胺重氮树脂.成膜树脂类型较多.就成膜角度看,能溶于合适溶剂的线型聚合体均可为成膜树脂.实际上并非如此,很多聚合体虽能与重氮树脂有共同的溶剂,并且本身可形成强度甚好的膜,以后可被显影除去,但并不能选作成膜树脂,主要原因是这些聚合体在光照下不能与重氮树脂光交联.

Abstract: Pbotocrosslinhng of four kinds of negative PS plate coatings consisting of diazo-resin of diphenylamine and binder-resins has been studied.The results show that the photocrosslinking could only take place in the coatings which contain binder-resins involving hydroxygroup;The tentative mechamism of photocrosslinking has been proposed.The relationship of crosslinking and diazo-resin content in coating was also disscused.

Key words: photocrosslinking, diazo-resin, binder-resin, negative PS plate
