Abstract
A network-like fine metal particle multilayer film has a network-like fine metal particle layer at least on one surface of a film substrate, which has an average total light transmittance of 70% or more, a total light transmittance variation of 5% or less, and a length of 2 m or more. The film is a long network-like metal fine particle multilayer film having high transparency, being suppressed in the occurrence of moiré and having small variations in the total light transmittance.

A network-like fine metal particle multilayer film comprising a network-like fine metal particle layer at least on one surface of a film substrate, which has an average total light transmittance of 70% or more, a total light transmittance variation of 5% or less, and a length of 2 m or more.
A method for producing a network-like fine metal particle multilayer film comprising coating at least one surface of a film substrate with a fine metal particle dispersion such that a fine metal particle layer network is laminated on the film substrate by die coating with a die containing a manifold with a volume of 0.01 cc to 5.0 cc per 10 mm die coating width.
