Abstract: The article presented the progress of image reversal components composing napthoquinone diazide compounds. The title image reversal components can be classified into three categories. The mechanism of first category is mainly based on decarboxylation,esterification and/or imide reaction;and that of the second is because of crosslinking reaction of binder resin and crosslinker or deblocking reaction in the presence of an acid which was produced by napthoquinone diazide compounds.The third category can be image reversed by near-UV and high energy exposure.The first and third image reversal components can be applied to photoresist and the second can be applied to printing plate possibly.

Key words: napthoquinone diazide compounds, image reversal, resist, printing plate
