Abstract
A high gloss photo media that has a gloss at 20 degrees equal to or greater than 40% includes a photo media substrate that includes a gloss-enhancement film on a front side of a photo base material. A curl control material is on a back side of the photo base material opposite the front side. The gloss-enhancement film being a multilayer that includes an adherent layer and a layer of one of a polyester composition and a polypropylene composition. A thickness of the gloss-enhancement film is at least 20 microns. The high gloss photo media further includes an image receiving layer on the gloss-enhancement film.
Claims15
A high gloss photo media comprising:
- a photo media substrate comprising a photo base material having a front side and a back side opposite the front side;
- a layer of a curl control material on the back side of the photo base material;
- and a gloss-enhancement film on the front side of the photo base material, a thickness of the gloss-enhancement film being at least 20 microns, the gloss-enhancement film being a multilayer comprising an adherent layer and a layer of one of a polyester composition and a polypropylene composition;
- and
- an image receiving layer on the gloss-enhancement film, the photo media having a gloss at 20 degrees that is equal to or greater than 40%.
A high gloss photo media comprising:
- a photo media substrate comprising:
- a layer of a polymer composition on a back side of a photo base material to control curl;
- and
- a gloss-enhancement film comprising an adherent layer and either a layer of polyethylene terephthalate (PET) or layers of polypropylene and poly(ethylene vinyl acetate) (PP and EVA) on a front side of the photo base material to enhance gloss of the photo media substrate, an amount of the curl control polymer composition being from 1.5 to 3 times an amount of the gloss-enhancement film, a thickness of the gloss-enhancement film being at least 28 microns;
- and
- an image receiving layer on the gloss-enhancement film, the photo media having a gloss at 20 degrees that is equal to or greater than 40%.
A method of preparing high gloss photo media, the method comprising:
- applying a curl control composition on a first side of a photo base material;
- applying a gloss-enhancement film to a second side of the photo base material, the gloss-enhancement film comprising an adherent layer and a layer of either a polyester composition or a polypropylene composition that are one of laminated, extruded and extrusion laminated to the photo base material, a thickness of the gloss-enhancement film being at least 20 microns;
- and
- applying an image receiving layer on the gloss-enhancement film, the photo media having a gloss at 20 degrees equal to or greater than 40% and a distinctness of image that is equal to or greater than 3.6 mm−1.
