Abstract
An ink composition for heat transfer printing comprising at least one of carbinol bases of basic dyes or their derivatives, a strong base, a binder and a solvent for dissolving the binder. This ink composition is excellent in storage stability because it contains a carbinol base of a basic dye or its derivative in isolated form as a coloring agent along with a strong base. By using this ink composition, a transfer sheet having high storage stability can be obtained.
