The PI solution includes PI molecules and a solvent. The PI molecules have hydrophobic moieties. The solvent include N-methyl-2-pyrrolidone, γ-butyrolactone, butyl carbonate, or a mixture thereof. The PI molecules of the PI solution contain hydrophobic moieties and in coating the PI solution to a substrate, the hydrophobic moieties link with organic compounds on the substrate thereby enhancing affinity of the PI solution with surface of the substrate, improving the issue of PI non-adherence, and the heightening quality of printing the substrate. | 04-23-2015 |
