PROBLEM TO BE SOLVED: To solve such a problem that an aggregate of a MgO powder being dispersed on a PDP protective film is generated, in a process for coating the PDP protective film with MgO powder, while inking, by means of a slit coater, and to provide a production method for suppressing generation of lumps, and to provide an ink.SOLUTION: An ink is composed of a MgO powder, a first solvent A, and second solvents B, C. The first solvent A evaporates at first, and the second solvents B, C evaporate substantially simultaneously. The first solvent A has the smallest surface-tension, the second solvent B has the largest surface-tension, and the solvent C has a surface-tension substantially equivalent to that of the first solvent A. |
