<P>PROBLEM TO BE SOLVED: To provide a transparent laminated film wherein an antireflection coating is provided on a substrate of a plastic film, which is equipped with the antireflection function of having excellent visible-light transmission properties and adequately reducing outside light reflection, and which makes unevenness in a reflection hue and lightness inconspicuous. <P>SOLUTION: In this transparent laminated film, a multi-layered thin film is formed on the substrate of the plastic film, and the unevenness of the reflection hue and the reflection lightness is decreased. In a CIE-Lab colorimetric system, a reflection hue represents an achromatic color (-1≤a<SP>*</SP>and b<SP>*</SP>≤2); a transmission hue represents an achromatic color (-2≤a<SP>*</SP>and b<SP>*</SP>≤2); and the lightness of the reflection is set at 2.5≤L≤3.5. In the CIE-Lab colorimetric system, the reflection hue represents a blue system (1≤a<SP>*</SP>≤10 and -15≤b<SP>*</SP>≤-3); the transmission hue represents the achromatic color (-2≤a<SP>*</SP>and b<SP>*</SP>≤2); and the lightness of the reflection is set at 2≤L≤3. <P>COPYRIGHT: (C)2004,JPO |
