Title:
TRANSPARENT CONDUCTIVE LAMINATE, TOUCHSCREEN, AND METHOD FOR MANUFACTURING TRANSPARENT CONDUCTIVE LAMINATE
Document Type and Number:
WIPO Patent Application WO/2016/002169
Kind Code:
A1
Abstract:
This transparent conductive laminate (10) is obtained by laminating together the following, in this order: a first undercoat layer that is between 20 and 35 nm thick, inclusive, and has an index of refraction between 1.61 and 1.80, inclusive; a second undercoat layer that is between 38 and 60 nm thick, inclusive, and has an index of refraction that is greater than or equal to 1.51 but lower than that of the first undercoat layer; and a transparent conductive layer that is between 31 and 38 nm thick, inclusive, and has an index of refraction of at least 1.81. When the transparent conductive layer (6) is patterned and a PET film is laminated thereto with a layer that comprises an adhesive and has an index of refraction of 1.47 interposed therebetween, the color difference (ΔE) between the region where the transparent conductive layer is present and a region where the transparent conductive layer is not present is less than or equal to 1 and the brightness difference (ΔL) between said regions is between −0.4 and 1, inclusive.
