PURPOSE:To provide a laminated sheet having excellent resistance to flexing and deformation and useful as a lithographic printing plate, by laminating an Al foil on a resin sheet consisting of an inorg. filler, a specified modified polyolefin and a polyolefin. CONSTITUTION:A mixture consisting of a polyolefin (A) having an MW of 20,000-1,000,000, such as PE, 0.5-20wt% modified polyolefin (B) obtd. by modifying 100pts.wt. polyolefin with 0.01-30pts.wt. unsaturated carboxylic acid and/or its derivative, such as maleic anhydride, and 20-70wt% inorg. filler having a particle size of 1mm. or below, such as CaCO3, is molded into a sheet to obtain a resin sheet 1 of 0.05-0.5mm. in thickness. An Al foil 2a of 6-200mum in thickness is laminated via an adhesive 3 on one side of the sheet 1. |
