Abstract: The present invention relates to a conductive paste or ink, which may be used to form conductive elements on the surface of a substrate, for example an electrode of a solar cell. The present invention also relates to a solar cell in which the upper electrode exposed to the sun is obtained by using said conductive paste or ink and a method for forming a conductive element on a substrate using said conductive paste or ink.

Abstract: The invention provides a multilayer silver halide color photographic element comprising a support having coated thereon at least two red-sensitive silver halide emulsion layers having different sensitivity to red light, characterized in that the most sensitive of said red-sensitive silver halide emulsion layers comprises a core-shell silver bromoiodide tabular emulsion having a pure bromide core, a total silver iodide content lower than 10% and an aspect ratio higher than 4.

Abstract: Multilayer color photographic element having on a support base blue-, green- and red-sensitive silver halide emulsion layers respectively associated with non-diffusing yellow, magenta and cyan dye-forming couplers, wherein (a) the green-sensitive silver halide emulsion layer comprises three green-sensitive silver halide emulsion layers, respectively uppermost, intermediate and lowermost, sensitive to the same spectral region of visible light, in which the sensitivity of the three green-sensitive silver halide emulsion layers decreases in order from the uppermost silver halide emulsion layer to the lowermost silver halide emulsion layer, (b) each of the three green-sensitive silver halide emulsion layers contains an 1-phenyl-3-anilino-4-phenylthio-5-pyrazolone magenta dye-forming coupler, (c) the weight ratio of the coupler to silver halide (expressed as silver) in the highest sensitivity uppermost green-sensitive silver halide emulsion layer is higher than the weight ratio of the coupler to silver halide (exp

Abstract: Silver halide photographic element comprising a support having coated thereon red-, green- and blue-sensitive silver halide emulsion layers comprising, respectively, cyan, magenta and yellow dye-forming couplers, wherein at least one silver halide emulsion layer comprises a yellow dye-forming DIR coupler having a 1,2,4-triazolyl group attached to the coupling position, said 1,2,4-triazolyl group comprising a hydrolyzable alkoxy- or aryloxy-carbonyl group attached to a benzylthio substituent on the 1,2,4-triazolyl group.Preferably, the yellow dye-forming DIR coupler is represented by the formula ##STR1## wherein R.sub.1 represents an alkyl group, an aryl group or --NHR.sub.5, wherein R.sub.5 represents an alkyl group or an aryl group,R.sub.2 represents an alkyl group or an aryl group, TIME represents a timing group,n is 0 or 1,R.sub.3 represents an alkyl group or a phenyl group, andR.sub.4 represents hydrogen atom or an alkyl group.
