PURPOSE:To provide a transfer sheet enabled in simple, safe and accurate transfer and facilitated in the reading of a transferred letter, consituted from a carbon transfer sheet having a carbon ink layer containing a specific amount of fatty amide and a carbon receiving layer. CONSTITUTION:A mixture consisting of a colorless-light colored electron donating org. compound [e.g., 3,3-(P-dimethyl-aminophenyl-6-dimethyaminophthalide)] or a phenolic hydroxyl group containing compound (e.g., bisphenol A) and 3- 80wt% pref., 5-50wt% fatty amide (e.g., stearyamide) solid at a room temp. is melted to be applied to a substrate sheet such as paper and the obtained coating layer is solidified by cooling to obtain a carbon transfer sheet 1 having a carbon ink layer 3 formed thereon. In the next step, the obtained sheet is combined with a carbon receiving sheet 2 having a fine random embossed pattern applied thereto to obtain desired copying sheet. |
