To provide a photosensitive resin composition which can simply and efficiently be produced, can reduce the environmental pollution in its production, and enables high resolving patterning, and a polybenzoxazole resin obtained from the photosensitive resin composition.
The photosensitive resin composition is obtained by compounding a polybenzoxazole precursor composed of a polyhydroxyazomethine with a sensitizer composed of a 1,4dihydropyridine derivative. This photosensitive resin composition is simply and efficiently produced and enables cost-cutting, reduction in environmental pollution, and improvement on corrosion resistance. The polybenzoxazole resin can be obtained in a positive pattern by exposing the photosensitive resin composition and developing the exposed photosensitive resin composition. This resin is patterned at a high resolving degree, has excellent electrical properties and mechanical properties, and can improve reliability.
