<p>Disclosed herein is a transfer material for use with a printer, which comprises a biaxially oriented polyester film which simultaneously satisfies the following expression (I) to (III): 12.0 </= F5 </= 17.0 (I) sigma </= 0.06 x F5 - 0.5 (II) Ep >/= 4 x 10<3> x DELTA np + 250 (III) wherein F5 represents the F5 value (kg/mm<2>) in the machine direction of said polyester film, sigma represents a heat shrinkage (%) in the machine direction of said polyester film after heat treatment at 100 DEG C for 30 minutes, Ep represents a Young's modulus (kg/mm<2>) in the machine direction, and DELTA np represents a degree of plane orientation of said polyester film, and a transfer ink layer formed on one surface or both surfaces of said polyester film. The transfer material according to the present invention is of great value in industry because the transfer material is excellent in durability and free from problems such as longitudinal tear and plastic strain. Also, the transfer material of the present invention has a capability of reducing the thickness without impairing the printing property thereof.</p> |
