<P>PROBLEM TO BE SOLVED: To provide conductive metal nanoparticle compositions with improved conductivity and that do not exhibit a coffee ring effect upon deposition. <P>SOLUTION: The metal nanoparticle composition includes an organic-stabilized metal nanoparticle and a solvent in which the solvent has the following Hansen solubility parameters: a dispersion parameter of about 16 MPa<SP POS="POST">0.5</SP>or more, and a sum of a polarity parameter and a hydrogen bonding parameter of about 8.0 MPa<SP POS="POST">0.5</SP>or less. The metal nanoparticle composition is suitable for printing conductive lines that are uniform, smooth, and narrow on various substrate surfaces. The metal nanoparticle composition is able to form printed conductive features having a coffee ring effect ratio of about 1.2 to about 0.8, a surface roughness of about 15 or less, and a line width of about 200 μm or less. <P>COPYRIGHT: (C)2012,JPO&INPIT |
