The invention has for its primary object to provide a solid composition having excellent wet-surface writing properties and high safety. The object is accomplished by the provision of a solid composition characterized by its comprising a colorant, a gelation agent, a resin component and at least two kinds of solvent, each of the resins having the following attribute a) or b): a) the solvent has an HLB value (X) of X ≤ 6.5 or b) the solvent has an HLB value (X) and a solubility parameter value (Y) satisfying the relation of Y ≤ 18 - X (on condition that 6.5 < X, 0 < Y). |
