Electromagnetic wave reflective film and method for producing same

摘要

Method for producing an electromagnetic wave reflective film by a first selective reflection layer forming process of using a transparent substrate; applying a first selective reflection layer forming coating solution on the transparent substrate to form a first selective reflection layer forming layer; irradiating the first selective reflection layer forming layer with ultraviolet rays at a dose in the range of 25 mJ/cm2 to 800 mJ/cm2; and thereby forming a first selective reflection layer; and a second selective reflection layer forming process of: using a second selective reflection layer forming coating solution; applying the second selective reflection layer forming coating solution on the first selective reflection layer so as to be in direct contact therewith to form a second selective reflection layer forming layer; irradiating the second selective reflection layer forming layer with ultraviolet rays; and thereby forming a second selective reflection layer.

1. A method for producing an electromagnetic wave reflective film, the method comprising steps of:
a first selective reflection layer forming process of: using a transparent substrate; applying a first selective reflection layer forming coating solution containing a rodlike compound represented by the following structural formula (I), a first chiral agent that imparts rotatory properties to the rodlike compound, and a first leveling agent, on the transparent substrate to form a first selective reflection layer forming layer; irradiating the first selective reflection layer forming layer with ultraviolet ray at a dose in the range of 25 mJ/cm2 to 800 mJ/cm2; and thereby forming a first selective reflection layer; and a second selective reflection layer forming process of: using a second selective reflection layer forming coating solution containing a rodlike compound represented by the following structural formula (I), a second chiral agent that imparts rotatory properties to the rodlike compound, and a second leveling agent; applying the second selective reflection layer forming coating solution on the first selective reflection layer so as to be in direct contact therewith to form a second selective reflection layer forming layer; irradiating the second selective reflection layer forming layer with ultraviolet ray; and thereby forming a second selective reflection layer:
