Five different forms,four ratioes and three kinds of alkali developable photosensitive resins were systhesized. Especially this paper studied their alkali developable as well as the light curing speed. Along with adding the ratio between photosensitive resin and maleic anhydride,alkali developable was better and the light curing speed was faster. When the ratio was more than 1:0.7,the resin had better alkali developable. Photoimage etching ink made up by alkali developable novolak epoxy acrylic resin had better alkali developable.
