Abstract
A thermal-transfer laminate film includes a base film, an untransferring release layer, and an image protection layer. The untransferring release layer is provided on the base film and includes a first thermoplastic resin having a first I/O value. The image protection layer is provided on the untransferring release layer and includes a second thermoplastic resin having a second I/O value, an absolute value of a difference between the first I/O value and the second I/O value being larger than 0.40.
Claims5
A thermal-transfer laminate film, comprising:

A thermal-transfer sheet, comprising:
- a base film;
- an untransferring release layer that is provided on the base film and includes a first thermoplastic resin having a first I/O value;
- an image protection layer that is provided on the untransferring release layer and includes a second thermoplastic resin having a second I/O value, an absolute value of a difference between the first I/O value and the second I/O value being larger than 0.40 and smaller than 0.75;

2 more elements
An image forming apparatus, comprising:
- a conveyor mechanism configured to convey a to-be-recorded medium in a predetermined direction;
- a thermal-transfer sheet including
- an untransferring release layer that includes a first thermoplastic resin having a first I/O value,
- an image protection layer that includes a second thermoplastic resin having a second I/O value, an absolute value of a difference between the first I/O value and the second I/O value being larger than 0.40 and smaller than 0.75, and
- an ink layer that is thermally transferred onto a surface of the to-be-recorded medium to form an image;
- a travel mechanism configured to cause the thermal-transfer sheet to travel;
- and
- a thermal-transfer head configured to cause one of the ink layer and the image protection layer of the thermal-transfer sheet to be thermally transferred onto the surface of the to-be-recorded medium.
