<p><P>PROBLEM TO BE SOLVED: To provide a waterproof laminated sheet which has a good printing aptitude even when a regenerated resin containing a low molecular weight substance is mixed in the inner layer. <P>SOLUTION: In the waterproof laminated sheet good in printing aptitude, at least two layers made of thermoplastic resins are laminated on at least one side of a substrate layer formed by a sheetlike support, the crystallinity of a thermoplastic resin used in the outermost layer is higher by at least 15% than that of a thermoplastic resin of a main component used in a layer contacting the inside of the outermost layer, and the regenerated thermoplastic resin is mixed in a layer other than the outermost layer. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
