Abstract: The components and methods disclosed herein are directed to positive type photosensitive resin compositions, which are comprised of an alkynyl containing polymer, a benzophenone type DNQ, and solvents. The alkynyl containing polymer is prepared by the condensation reaction of alkynyl containing dianhydrides and hydroxyl containing diamines, and alkynyl containing end cappers. The advantage of this formulation is that the resulting photosensitive resin composition is comprised of only a polymer, a benzophenone type DNQ PAC, and solvents that generates high resolution patterned films with good thermal and physical properties without using additional additives. This composition also enables film curing at relatively low temperatures without additional additives, simplifying the composition. After curing, the alkynyl units in the polymer chain and the chain ends give the cured film excellent solvent resistance and film retention due to intra and/or inter-molecular crosslinking.
