Title:
LAMINATE, TRANSPARENT CONDUCTIVE LAMINATE, TOUCH PANEL, AND METHOD FOR PRODUCING LAMINATE
Document Type and Number:
WIPO Patent Application WO/2013/021965
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a laminate which is provided with a multilayer film having a refractive index modulation function on at least one surface of a supporting base and which has high transparency and high electrical conductivity in cases where a transparent conductive layer is laminated on the outermost surface of the multilayer film, said laminate exhibiting good adhesion of the transparent conductive layer to the multilayer film without highlighting the patterning of the transparent conductive layer, while being suppressed in coloring of transmitted light; a transparent conductive laminate which is obtained by laminating a transparent conductive layer on the laminate; and a touch panel which uses the transparent conductive laminate.
A laminate of the present invention comprises, on at least one surface of a supporting base, a multilayer film that is composed of two layers having different refractive indexes, and is characterized in that: the two layers constituting the multilayer film are a first layer and a second layer; the first layer, the second layer and the supporting base are sequentially laminated in this order; the first layer contains inorganic particles A; and the number average particle diameter (DA) of the inorganic particles A and the thickness (T1) of the first layer satisfy the following condition.
0.9 ≤ (T1/DA) ≤ 2.0
