PROBLEM TO BE SOLVED: To obtain a thermal transfer ink sheet having excellent safety regarding an environmental problem or the like by holding a heat resistant ink containing no lead and no bismuth or transparent glass powder and organic binder as at least components at a support base material. SOLUTION: The thermal transfer ink sheet adapted to formation or the like of a baking label is formed by holding a heat resistant ink containing no lead and no bismuth and containing colored or transparent glass powder and an organic binder as at least components at a support base material. The powder to be used is retained as ink information by fusion bonding in the case of baking a baking sheet and bonding to a baked material of the baking sheet, and fixed to the baking material. The colored or transparent powder containing no toxic component such as the lead and the bismuth is used. The powder to be used preferably contains a phosphoric acid, zinc and alumina as components from points of safety by avoiding its toxicity and low temperature fixability or the like. |
