PROBLEM TO BE SOLVED: To provide an aluminum alloy sheet for a lithographic printing plate which is formed with uniform pits by electrochemical surface roughening treatment and has an excellent strength and thermosoftening resistance. SOLUTION: The aluminum alloy sheet for a lithographic printing plate contains 0.1 to 0.3% Mg, over 0.05 to≤0.5% Zn, 0.2 to 0.6% Fe, 0.03 to 0.15% Si,≤0.02% Cu, and 0.03 to 0.05% Ti and consists of the balance Al and impurities. Over 0.05 to≤0.3% Mn may also be added thereto. COPYRIGHT: (C)2005,JPO&NCIPI
