Abstract: A recording material which comprises a polymeric substrate having two surfaces, wherein one surface is coated with a sealing layer comprising a particulate polymer having a film forming temperature of between 60° C. and 160° C. and an average particle size between 1 ?m and 50 ?m together with at least one binder, and at least one ink receiving layer; and the opposite surface is coated with an adhesive layer covered by a release liner. A related printing method whereby an image printed on the recording material is heated after printing to seal the sealing layer to provide a protected surface.

Abstract: There is described a recording medium and related ink jet printing method which comprises the steps of: 1) printing onto a receiving medium which comprises a substrate coated with at least one ink receiving layer comprising polymeric particles having film forming temperatures between 60° to 140 ° C. and a binder, and 2) heating the printed image to form a stable image-protecting coating. Preferably the printed image is heated by passing through a laminator. Alternatively the printed image is heated by passing through a laminator in conjunction with a second, inert releasing sheet which is held against the top surface of the print material. The second sheet may be used to produce a particular appearance to the final image such as high gloss or a security pattern. The receiving layers of the invention provide bright images after printing and fusing which show a high level of scratch and rub resistance even when wet.

Abstract: A recording medium comprising a substrate coated with at least one ink receiving layer and at least one protective layer which comprises polymeric particles having film forming temperatures between 60 to 140° C., preferably between 100 to 120° C., and at least one binder. In the related printing method, the printed medium is heated to form a stable image protecting coating.

Abstract: There is provided an aqueous ink jet ink composition suitable for use in continuous ink jet printers comprising:

Abstract: There is provided a pigmented aqueous ink set including: (a) A concentrated black ink having a pigment concentration up to 10% by weight; and (b) at least one dilute ink having a pigment concentration below that of the concentrated ink; wherein all the inks additionally includes an aqueous carrier medium and at least one of the set of inks includes a combination of carbon black and Pigment Blue 60.

Abstract: A pigmented aqueous ink jet ink composition is provided which comprises a sarcosinate compound of the formula: R—CO—NMe—CH2—COOM In which R is a ballasting group comprising at least ten carbon atoms and M is hydrogen, an alkali metal cation, an ammonium cation or a substituted ammonium cation. Preferably the ink is prepared by dispersing the pigment in the presence of the sarcosinate compound in water, together with optional co-solvents or other components, and then diluting this dispersion to form the ink.

Abstract: There is provided a pigmented aqueous ink set which comprises: (a) a cyan ink which comprises at least one pigment which is a phthalocyanine compound; (b) a magenta ink which comprises at least one pigment which is a quinacridone compound; (c) a yellow ink wherein the pigment is C.I. Pigment Yellow 155; (d) a green ink wherein the pigment is selected from the group consisting of C.I. Pigment Green 7, 36, and mixtures thereof; (e) an orange ink wherein the pigment is selected from the group consisting of C.I. Pigment Orange 34, 36, 43, 61, 64, 71, and mixtures thereof; together with optionally (f) a black ink which comprises a black pigment. Preferably there is also present at least one water soluble organic cosolvent. The pigmented ink set is suitable for use in ink jet printing.
