PROBLEM TO BE SOLVED: To prevent the generation of blocking when the softening point of a bonding layer is lowered for the purpose of improving transfer sensitivity by forming a layer having the glass transition point of a specified temperature or above and composed of a resin of a melting viscosity at a specified temperature lower than a specified vlaue as a main component between a metal deposit layer and the bonding layer. SOLUTION: A colored or uncolored ink layer, a metal deposit layer, a heat- resistant layer and a bonding layer are formed on one face of a base in the above-referred order. The heat-resistant layer is composed of a resin having the glass transition point of 65 deg.C or above and the melting viscosity at 160 deg.C of 1×10<3> cPs or under as a main component. The heat-resistant layer is formed between the metal deposit layer and the bonding layer. Blocking is not generated when the softening point of the bonding layer is lowered, namely approximately 50-70 deg.C by the arrangement. When the glass transition point of the resin as the main component is lower than 65 deg.C, the blocking effect gets inferior, and when the melting viscosity of the resin as the main component at 160 deg.C is higher than 1×10<3> cPs, the transfer sensitivity is lowered. |
