Title:
TRANSLUCENT ELECTROMAGNETIC WAVE SHIELDING MEMBER AND ITS PRODUCING METHOD
Document Type and Number:
Japanese Patent JP2002057490
Kind Code:
A
Abstract:

To provide a translucent electromagnetic wave shielding member, exhibiting both superior translucence and electromagnetic wave shielding effect and having no possibility of lowering contrast, and to provide its producing method.

In the translucent electromagnetic wave shielding member, a print pattern 10, having line width of 5-40 μm and satisfying formula (1): 1≤Sk/Ss≤9 (1) [in the formula, Ss is the total surface area of a printed region on the surface of a transparent substrate, Sk is the total surface area of unprinted region] is formed on the surface of the transparent substrate 2, by printing a conductive ink composition containing conductive powder. The print pattern 10 is then fired at 250-600°C to constitute an electromagnetic wave shield pattern 1. The print pattern is formed through intaglio offset printing.
