A hydroxylamine-gallic compound composition comprises a hydroxylamine compound, at least one alcohol amine compound which is miscible with the hydroxylamine compound and a gallic compound. A process for removing photoresist or other polymeric material or a residue from a substrate, such as an integrated circuit semiconductor wafer including titanium metallurgy, in accordance with this invention comprises contacting the substrate with a hydroxylamine compound, an alcohol amine compound which is miscible with the hydroxylamine compound and a gallic compound for a time and at a temperature sufficient to remove the photoresist, other polymeric material or residue from the substrate. Use of a gallic compound in place of catechol in the composition and process reduces attack on titanium metallurgy by, e.g., about three times.
