<p><P>PROBLEM TO BE SOLVED: To provide a laminated steel sheet for a two-piece can capable of preventing the peeling and breakage of a laminate resin layer even if a can body enhanced in processing degree like an aerosol two-piece can is manufactured. <P>SOLUTION: The laminated steel sheet for the two-piece can, wherein the height (h), maximum radius (r) and minimum radius (d) of a final formed product satisfy the relation of 0.1≤d/R≤0.25 and 1.5≤h/(R-r)≤4 with respect to the radius R of a circular sheet before forming becoming equivalent to the final formed product in weight, has a polyester resin coating layer comprising a resin which is obtained by the polycondensation of a dicarboxylic acid component and a diol component and characterized in that the dicarboxylic acid component is based mainly on terephthalic acid, an isophthalic acid component is contained or not contained in another copolymerizing component, the diol component is based mainly on ethylene glycol and/or butylene glycol and diethylene glycol and cyclohexane diol are contained or not contained in another copolymerizing component, the copolymerizing component is less than 8 mol% as a molar ratio and the coefficient of surface orientation is 0.06 or below. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
