Abstract
Abstract A thermo-transfer sheet is composed of a base film and an ink layer to be transferred having a softening point of more than 120°C . A label is formed by the thermo-transfer sheet and provided with an image ink layer formed on a thermo-transfer image receiving sheet through a temperature-sensitive adhesive layer and the image ink layer has a softening point of more than 120°C . The thermo-transfer sheet and the thermo-transfer image receiving sheet are prepared and a temperature-sensitive adhesive layer is formed on at least one of the surface of the thermo-transfer sheet or the transfer ink layer of the thermo-transfer image receiving sheet. These sheets are laminated and the laminated sheets are heated by means of a thermal head to thereby transfer the image ink layer having a softening point of more than 120 °C on the thermo-transfer image receiving sheet. According to these processes, a label such as bar code is manufactured with an excellent durability such as friction-proof property, solvent-proof property and heat-proof property.
