Patent number: 6902268Abstract: 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.Type: GrantFiled: November 15, 2000Date of Patent: June 7, 2005Assignees: ILFORD Imaging Switzerland GmbH, ILFORD Imaging UK LimitedInventors: Jeffrey Ronald King, Karen Taylor, Simon Richard John Leggett, Stefan Schüttel, Roger Leslie Brentnall
