PURPOSE: To obtain a printing paint composition for an inert thermoplastic elastomer, increased in the stability of adhesion to an elastomer, by using the same polymer as that of the object to be printed or a polymer of a molecular structure similar to that of the object as a base for the paint composition.

CONSTITUTION: The same polymer as that of the object to be printed or a polymer having a molecular structure similar to that of the object as a base of a coating is dissolved in a solvent, and a pigment and various additives are added to the solution to obtain a printing paint composition for a thermoplastic elastomer.
