Abstract
A thermal transfer sheet includes a support film and a transfer layer provided on one surface of the support film. The transfer layer at least includes a decorative layer and an adhesive layer provided on an obverse side of the decorative layer. The adhesive layer includes a first adhesive layer and a second adhesive layer laminated on the first adhesive layer. The first adhesive layer is positioned on an obverse side of the second adhesive layer. The first adhesive layer is made of a first resin having thermal plasticity and has a lower viscosity than the second adhesive layer. The second adhesive layer is made of a second resin having thermal plasticity and has a higher glass-transition point than the first adhesive layer. Monomer units constituting the first resin and monomer units constituting the second resin are partly or entirely identical.
