Title:
SUBSTRATE WITH ELECTRICALLY CONDUCTIVE LAYERS, AND TOUCH PANEL
Document Type and Number:
WIPO Patent Application WO/2020/203447
Kind Code:
A1
Abstract:
The present invention provides a substrate with electrically conductive layers that has good color and excellent migration resistance, and a touch panel in which the substrate is used. A substrate with electrically conductive layers that has at least a second electrically conductive layer (A-2), a second insulating layer (OC-2), a first electrically conductive layer (A-1), and a first insulating layer (OC-1) on a substrate (S-1). The substrate with electrically conductive layers satisfies all of equations (1) to (3) when the b* value of the substrate (S-1), as defined by the L*a*b* color system provided by the International Commission on Illumination 1976, is b*(S-1), the b* value of the first insulating layer (OC-1) is b*(OC-1), and the b* value of the entire substrate with electrically conductive layers is b*(T). (1): -4.3 ≤ b*(T) ≤ 2.0
(2): 0.8 ≤ b*(S-1) ≤ 5.0
(3): 1.5 ≤ b*(T) - b*(OC-1) ≤ 5.5
