| 摘要 |
<p>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), <MATH> wherein eta 12-2 is a melt viscosity at an extrusion temperature of the polyester at a shearing rate of 12.2 sec<-1>, and eta 1216 is a melt viscosity at an extrusion temperature of the polyester at a shearing rate of 1216 sec<-1>, of not smaller than 2.0 at a melt extrusion temperature of the polyester, and having eta 1216 of not smaller than 500 poises, and said resin layer being further quickly quenched after it is melt-extruded. <IMAGE></p> |
