<p><P>PROBLEM TO BE SOLVED: To provide a film in which brittleness of a crystalline polylactic acid is conquered, which excels in impact resistance, laminating properties, interlayer adhesive properties, and ornament properties having high transparency and vividness, and to provide an ornament material or a packaging material with a small environmental load and a near-infrared ray cut film of very high transparency. <P>SOLUTION: The laminated film of this invention comprises a layer which makes a polylactic acid based polymer as a principal component (layer A) and a layer which makes a resin having a structure represented by structural formula (1) as a principal component (B layer) which are made to be arranged by turns in the thickness direction, wherein the difference of inplane average indexes of refraction between layer A and layer B is 0.01 or more, and includes 20 or more layers, wherein the thickness of one layer is from 0.03 micrometers or more to 0.5 micrometers or less. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
