Conductive element precursor and conductive pattern formation

摘要

A black-and-white silver halide conductive film element precursor has at least one first non-color hydrophilic photosensitive layer comprising a silver halide and a first hydrophilic overcoat disposed over the first non-color hydrophilic photosensitive layer. This first hydrophilic overcoat is the outermost layer and contains one or more immobilized radiation absorbers such as immobilized ultraviolet radiation absorbers, in a total amount of at least 5 mg/m2. 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. In many instances, the precursors have the same or different layers on both sides of a transparent substrate and the resulting conductive film element has the same or different conductive silver patterns on both sides.

1. A black-and-white silver halide conductive film element precursor comprising a transparent substrate comprising a first supporting side and an opposing second supporting side, and having disposed on the first supporting side:
a first non-color hydrophilic photosensitive layer comprising a silver halide coverage of at least 3,500 mg Ag/m2, and a first hydrophilic overcoat disposed over the first non-color hydrophilic photosensitive layer, which first hydrophilic overcoat is the outermost layer on the first supporting side of the transparent substrate, and the first hydrophilic overcoat comprises: (a) one or more immobilized radiation absorbers in a total amount of at least 5 mg/m2, and optionally (b) one or more silver halides in a total amount of at least 5 mg Ag/m2.
