Abstract
A laminate obtained by laminating a resin composed chiefly of a polyester on a base material, said resin layer having a melt viscosity ratio (R) defined by the following formula (1), EQU R=.eta..sub.12.2 /.eta..sub.1216 (1) PA1 wherein .eta..sub.12.2 is a melt viscosity at an extrusion temperature of the polyester at a shearing rate of 12.2 sec.sup.-1, and .eta..sub.1216 is a melt viscosity at an extrusion temperature of the polyester at a shearing rate of 1216 sec.sup.-1, of not smaller than 2.0 at a melt extrusion temperature of the polyester, and having .eta..sub.1216 of not smaller than 500 poises, and said resin layer being further quickly quenched after it is melt-extruded.
