PHYSICAL DEVELOPER, METHOD OF PREPARING CONDUCTIVE PATTERN, ELECTROMAGNETIC WAVE SHIELDING MATERIAL, FITTER FOR PLASMA DISPLAY AND PANEL FOR PLASMA DISPLAY

摘要

A method of preparing a conductive pattern, in which micro patterning can be realized and in which a conductive pattern with high conductivity and light transmission can be obtained at low cost; a physical developer for use in the method that has an enhanced storability; and, obtained by the above method of preparing a conductive pattern, an electromagnetic wave shielding material, fitter for plasma display and panel for plasma display. The physical developer is one for use in preparation of a conductive pattern, characterized in that it is produced by mixing of a reducing agent with a silver compound in the presence of a buffering agent and has a pH value of 2 to 4.
