Abstract: Zinc salts have been found to provide anticorrosion properties when incorporated into silver nanowire containing films. Such salts may be incorporated into one of more silver nanowire containing layers or in one or more layers disposed adjacent to the silver nanowire containing layers.

Abstract: The present invention provides heat-developable, photothermographic elements comprising a support bearing at least one photosensitive, image-forming layer comprising:(a) a photosensitive silver halide;(b) a non-photosensitive, reducible silver source;(c) a reducing agent for silver ions;(d) a binder; and(e) a spectrally sensitizing amount of a compound having the central nucleus: ##STR1## wherein: Z is S, O, Se or N--R.sup.3 ;R.sup.1 and R.sup.2 represent an alkyl group of from 1 to 20 carbon atoms other than carboxy-substituted alkyl, preferably an alkyl group of from 1 to 8 carbon atoms, and most preferably an ethyl group; andR.sup.3 is H or alkyl group;X and Y are thioalkyl groups of from 1 to 20 carbon atoms;n=0 to 4;m=0 to 4; the sum of n plus m equals at least 1;D.sup.1 to D.sup.7 each independently represents a methine group and adjacent methine groups selected from D.sup.2, D.sup.3, D.sup.4, D.sup.5 and D.sup.6 may form cyclic groups;p=0 or 1; andA.sup.- is an anion.

Abstract: Photothermographic elements of the photothermographic type may be sensitized to the infrared with sensitizing dyes of the formula: ##STR1## wherein: R.sup.1 represents a (CH.sub.2).sub.n --COO.sup.- group of from 1-20 carbon atoms, or an alkyl group of from 1 to 20 carbon atoms; andn is an integer from 1 to 20.
