ABSTRACT:
A process of forming a polyimide pattern on a base plate, which comprises exposing imagewise a layer of photosensitive polyimide precursor on the base plate, removing unexposed areas by developing and curing the resultant pattern of the polyimide precursor, characterized by employing a developer containing (A) at least one solvent selected from the group consisting of N,N-dimethylacetamide, N-methyl-2-pyrrolidone, N,N-dimethylformamide, dimethylsulfoxide and .gamma.-butyrolactone, (B) methanol and (C) at least one solvent represented by the formula;
