The invention provides a dyeing solution for lithographic printing plates and a dyeing method for waterless lithographic printing plates that show stable plate inspection characteristics with little decrease in dye concentration and less dyeing unevenness even when used for bulk plate processing. The dyeing method for waterless lithographic printing plates is designed so that when used to dye an image area formed on a waterless lithographic printing plate with a dyeing solution containing an organic solvent, the relation of |β−α|<5 (cal/cm.sup.3).sup.1/2 is held wherein β is the SP value of the polymer compound included in the image area and α is the SP value of the organic solvent. The dyeing solution for lithographic printing plates contains (a) a dye, (b) a specific anionic surface active agent, and (c) an organic solvent containing at least one selected from ethers and alcohols.

This disclosure describes manufacture of a mixture and use of same to fabricate different types of electronic components. In one configuration, the mixture includes: first particles, the first particles being an insulator material; second particles, the second particles being electrically conductive metal material; and a combination of the first particles and the second particles suspended in a printable liquid medium, the printable liquid/solid medium (slurry) being curable into a dielectric layer of material. According to one configuration, the printable material is disposed and cured on a substrate. The first particles and second particles are randomly distributed in the cured printed material (dielectric material). The second particles in the cured dielectric material are transformable into one or more electrically conductive paths, electronic components, etc., via application of heat above a threshold value. Thus, a dielectric (insulator) material can be transformed into an electrically conductive path via application of heat.
