<P>PROBLEM TO BE SOLVED: To provide a film and the like for preventing bird injury, having a simple structure, capable of generating a very strong evading reaction in birds even in the flat planar state, and exhibiting the evading effect for a long period of time. <P>SOLUTION: The film 1 for preventing bird injury includes a metal-evaporated layer with a hologram forming surface on one surface of a base material, and a colored layer 30 with colored transparent printed layers on the hologram forming surface of the metal-evaporated layer. The colored layer 30 includes band-shaped colored transparent printed layers of three colors including red 31a, yellow 31b and green 31c; and the respective colored transparent printed layers are repeatedly disposed. The colored layer has such color arrangement that the yellow band-shaped colored transparent printed layer 31b is disposed between the green band-shaped colored transparent printed layer 31c and the red band-shaped colored transparent layer 31a. The relation among widths of the respective band-shaped colored transparent printed layers is; the width of the yellow layer<the width of the red layer<the width of the green layer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
