Abstract

A metallic nanoparticle dispersion includes metallic nanoparticles, a liquid carrier, and a dispersion-stabilizing compound according to Formulae I, II, III or IV, wherein Q represents the necessary atoms to form a substituted or unsubstituted a five or six membered heteroaromatic ring; M is selected from the group consisting of a proton, a monovalent cationic group and an acyl group; R1 and R2 are independently selected from the group consisting of a hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted alkaryl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl or heteroaryl group, a hydroxyl group, a thioether, an ether, an ester, an amide, an amine, a halogen, a ketone and an aldehyde, R1 and R2 may represent the necessary atoms to form a five to seven membered ring; R3 to R5 are independently selected from the group consisting of a hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted alkaryl group,…
