Title:
FUNCTIONAL FILM
Document Type and Number:
Japanese Patent JP2010099979
Kind Code:
A
Abstract:
To provide a functional film in which deterioration caused by a change in color is suppressed even containing a heat ray shielding agent including a tungsten compound.
The functional film containing at least a heat ray shielding layer 110 is characterized in that the heat ray shielding layer 110 contains the tungsten compound as a heat ray shielding agent and the heat ray shielding layer 110 or other layers 121, 122 contain ultraviolet absorbing agents having maximum absorbing wavelengths within a range from 315 to 420 nm and an ultraviolet absorbing agent b having the maximum absorbing wavelength within a range not higher than 310 nm.
