Abstract
A dye diffusion thermal transfer carrier material comprises a base material and an intermediate layer which contains a film forming binder with a minimum film forming temperature of at least 25.degree. C., and a pigment of hollow polymer micropellets in which the micropellets have an interior space that has a volume that is between 10 and 55% of the total volume of the micropellet body.
Claims15
A dye diffusion thermal transfer carrier material for carrying a dye receptor layer, comprising:
- a base material;
- and
- a layer on said base material which is adapted to receive the receptor layer thereon and which contains a film forming binder with a minimum film forming temperature of at least 25.degree. C., and a pigment in the form of hollow polymer micropellets in which the micropellets have an interior space with a volume that is between about 10 and 55% of the total volume of the micropellet body, and wherein the amount of said micropellets in said layer is about 4-30 wt %.
