A 6,6′-dialkyl-3,3′,4,4′-biphenyltetracarboxylic dianhydride is prepared by brominating a 4-alkylphthalic anhydride at its 5-position, and coupling the bromination product in the presence of a nickel catalyst; A photosensitive resin composition containing a polyimide precursor having repetitive units of general formula (7) is applied onto a substrate, exposed to i-line, developed and heated to form a polyimide relief pattern. wherein Y is a divalent organic group, R7and R8are OH or a monovalent organic group, R9and R10are a monovalent hydrocarbon group, R11, R12and R13are a monovalent hydrocarbon group, a and b are an integer of 0 to 2, c is an integer of 0 to 4, and m is an integer of 0 to 3.
