Patent ID: 7879525

Claim:
A photoresist laminated product comprising a support, including copper within at least a portion of the upper surface of the support laminated on the surface of the support, and a photoresist layer consisting of a positive photoresist composition including (a) a resin that undergoes a change in alkali solubility under the action of acid, (b) a compound that generates acid upon irradiation, and (c) a corrosion inhibitor, wherein said corrosion inhibitor (c) is represented by a general formula (IV); [wherein, R 10 represents a hydrogen atom or a mercapto group, R 11 and R 12 each independently represent, a halogen atom, a hydrogen atom, a hydroxyl group, an amino group, a mercapto group, a substituted or unsubstituted hydrocarbon of 1 to 10 carbon atoms, a substituted or unsubstituted alkyloxy group of 1 to 10 carbon atoms, or a hydrocarbon-substituted amino group of 1 to 10 carbon atoms], wherein the proportion of the corrosion inhibitor (c) is within a range from 0.01 to 5 parts by weight, per 100 parts by weight of the resin (a).
