| 摘要 |
The invention provides a method for producing a PTC ink composition, which is capable of reducing the degree of deformation (curving, warping, curling, etc.) of dried ink after printing while maintaining mass productivity, and the PTC ink composition. According to the method for producing a PTC ink composition of the invention and the PTC ink composition obtained by this method, a non-polar rubber solution prepared by dissolving a non-polar rubber in a non-polar solvent selected from aliphatic hydrocarbons, aromatic hydrocarbons, and mixtures thereof, is added to a conductive particle-containing PTC (Positive Temperature Coefficient) ink composition obtained by dissolving under heat an ethylene-acrylic acid copolymer (EAA) having an acrylic acid content of 20 wt. % or less in decalin, tetralin, or a mixture thereof; and a polar solvent is added to the resulting mixture.
