In this study, we synthesized novel UV-curable binders and applied for negative photoresist of display device. First, we synthesized UV-curable binders by radical polymerization with a mixture of Styrene/Methyl methacrylate/Methacrylic acid/Glycidyl methacrylate/N-Cyclohexylmaleimide at a fixed composition. Following the first step, we prepared a negative photoresist mixture optimized with photo sensitive initiator and others for the litho test. And then, we studied resolution and film retention with molecular weight of each binders and numerical value of Alkaline Desolution Rate(ADR). As a result of the litho test, we found that if the novel polymers have same numerical value of ADR, the resolution decreased and the film retention increased with the increasing of molecular weight of photoresist binder.
