A donor element useful in an assemblage for imaging by exposure to light comprises a support layer, a light-to-heat conversion layer disposed adjacent the support layer containing a light absorber, and a transfer layer disposed adjacent the light-to-heat conversion layer opposite the support layer. The donor element also includes a release-modifier disposed between the support layer and the transfer layer.

Donor element with release-modifier for thermal transfer

A donor element useful in an assemblage for imaging by exposure to light comprises a support layer formed by a stretching process, a light-to-heat conversion layer disposed adjacent the support layer containing a light absorber, and a transfer layer disposed adjacent the light-to-heat conversion layer opposite the support layer. The light-to-heat conversion layer is coated on the support prior to completion of the stretching process.

A composite film is described which consists of a primary unfilled polyester layer and a secondary polyester layer containing from 1 to 8% by weight, based on the weight of the secondary polyester layer, of finely divided silica particles having a volume weighted mean particle size diameter D&lsqb;4,3&rsqb; of from 2.3 to 6.2 micrometers. The composite film is used in backlit displays such as illuminated signboards and provides uniform light transmission while maintaining the same strength of illumination at all points over the area of the display.
