ABSTRACT:
A solvent composition which comprises a fluorinated solvent containing no chlorine atom in its molecule, a hydrocarbon solvent and a glycol ether and which is free from phase separation, wherein the compositional ratio of the fluorinated solvent and the hydrocarbon solvent is a compositional ratio such that a two component mixture composed solely of the fluorinated solvent and the hydrocarbon in such a compositional ratio would separate into two phases.
