A multilayer white polymeric film having a core layer with an optical transmission density greater than 2.0, a white polyester outer layer on either side of the core layer and an ink receptive layer on the outer surface of the white polyester layers.

Opaque polyester film as substrate with white coatings on both sides

A thermal transfer printing receiver sheet for use in association with a compatible donor sheet, the receiver sheet comprising a receiving layer to receive a dye thermally transferred from the associated compatible donor sheet, and further comprising a release medium and adhesion-promoting medium and an antistatic medium, wherein said release medium, said adhesion-promoting medium and said anti-static medium are, independently, present as a coating on at least part of at least one surface of the receiving layer or present in the receiving layer; use thereof as a clear printable overlaminate; and a laminated multilayer film comprising one or more of said receiver sheet(s) and a backing sheet comprising a film-forming material.

Multilayer film

A polyester film having an opaque first polyester layer having an optical density greater than 2.0 and a second white polyester layer, wherein the film is made by coextrusion. The opaque first layer preferably contains carbon black. The film is suitable for use as a base for a photographic sheet.

Polyester film

Receiver sheet for thermal dye transfer printing

A release film comprises a polymeric film substrate and a polymeric abherent layer. The abherent layer comprises a polyurethane resin which is the reaction product of:

Release film comprising polycarbonate-silicone-urethane resin

Receiver sheet

A thermal transfer printing receiver sheet for use in association with a compatible donor sheet. The receiver sheet comprises in order (i) a supporting substrate comprising a layer of a synthetic polymer having a deformation index, at a temperature of 200.degree. C. and under a pressure of 2 megapascals, of at least 4.5%, (ii) a polymeric intermediate layer having a Transmission Optical Density/film thickness (in mm) ratio of from 7.5 to 17.5, and (iii) a dye-receptive receiving layer to receive a dye thermally transferred from the donor sheet.

A thermal transfer printing (TTP) receiver sheet has a dye-receptive receiving layer to receiver a dye thermally transferred from a donor sheet, and a substrate comprising a layer of a synthetic polymer having a deformation index, at a temperature of 200.degree. C. and under a pressure of 2 megaPascals, of at least 4.5%.

A TTP receiver sheet having a backing layer comprising a polymeric resin binder and a non-film forming inert particulate material of mean particle size from 5 to 250 nm.

A thermal transfer printing (TTP) receiver sheet has a substrate, dye receptive receiving layer and a release medium associated with the receiving layer, the release medium being a dye-permeable polyurethane resin which is the reaction product of (i) an organic polyisocyanate, (ii) an isocyanate-reactive polydialkylsiloxane, and (iii) a polymeric polyol.

A thermal transfer printing (TTP) receiver sheet for use in association with a compatible donor sheet, comprises a supporting substrate having, on at least one surface thereof, (a) a dye-receptive receiving layer to receive a dye thermally transferred form the donor sheet, said receiver sheet additionally comprises, on at least one surface thereof, (b) an antistatic layer, said antistatic layer preferably being on a second surface of said substrate. The antistatic layer preferably comprises (a) a polychlorhydrin ether of an ethoxylated hydroxyamine and (b) a polyglycol amine, the total alkali metal consent of components (a) and (b) not exceeding 0.5% of the combined weight of (a) and (b).
