CONDUCTIVE ELEMENT PRECURSOR AND CONDUCTIVE PATTERN FORMATION

摘要

Black-and-white silver halide conductive film element precursors have, on one or both sides and in order, a UV filter layer, non-color hydrophilic photosensitive layer comprising a silver halide, and a hydrophilic overcoat as an outer layer. The one or two UV filter layers individually contains one or more UV absorbing agents in an amount of up 0.5 mmol/m2 and the total amount in the precursor is up to 1 mmol/m2 to prevent crosstalk during imagewise exposure. These precursors can be imagewise exposed and processed to provide conductive film elements with various conductive silver patterns (or grids) with narrow conductive silver lines on one or both sides. Such conductive film elements can be prepared with reduced yellowness as evidenced by reduced b* values. The resulting conductive film elements are highly transparent and can be used in various devices such as display devices.
