Definitions

• This invention relates to a method for ink-jet printing of materials. More particularly the present invention relates to a method to provide any given substrate with an ink-receiving layer as normally used in ink-jet printing.
• Ink-jet printing has become a popular printing technique because of its convenience, simplicity and low cost. Especially in those instances where a limited edition of the printed matter is needed, ink-jet printing has become a printing technology of choice.
• the individual ink droplets can be applied to the receiving substrate in several different ways.
• the ink solution can be jetted continuously through a small nozzle towards the receiving layer (Hertz method).
• the ink droplet can also be created "upon demand” by a piezoelectric transducer or a thermal push (Bubble Jet).
• Ink-jet printing can be used both on plain paper substrates and on (transparent) polymeric substrates.
• ink-jet printing lies in the production of transparencies on a transparent polymeric substrate. These elements are primarily intended for use on an overhead projector. More generally, these elements can be used for all kinds of viewing means by transmitted light.
• transparencies can be made by ink-jet printing on a plain polymeric substrate when using a hot-melt ink-jet printing technique.
• a high viscosity ink is melt and jetted upon the plain polymer substrate.
• the ink readily cools down, solidifies and adheres well to the substrate.
• This technique presents some disadvantages : the solidified ink yields small lenses upon the surface of the transparencies which can lead to colour changes during projection with directed light. The surface irregularities can also lead to scratching and damaging of the information contained in the transparencies.
• Ink-receiving layers used in image-recording members comprising a polymeric substrate meeting the necessary different stringent requirements for high quality ink-jet printing are disclosed in e.g. German Patent Application DE 2,234,823, US P 3,889,270, US P 4,503,111, US P 3,357,846, US P 3,889,270, DE 2,925,769, GB 2,050,866, US P 4,474,850, US P 4,547,405, US 4,578,285, WO 88 06532, US P 4,849,286, EP 339 604, EP 400 681, EP 407 881, EP 411 638 and US 5,045,864.
• Image-recording members comprising an ink-receiving layer according to any of the disclosures mentionned above can advantageously be used in ink-jet printing, but still present the drawback that ink-jet printing is only possible on the substrate provided by the manufacturer of the image recording member.
• the objects of the present invention are realized by providing a method for applying an ink-receiving layer to any given substrate comprising the steps of
• step i. of said method is carried out with a sheet or web material of which the temporary support is a polyethyleneterephthalate film.
• the temporary support is a polyethyleneterephthalate film with a thickness between 50 and 70 ⁇ m.
• the web or sheet material to be used in step i. of said method comprises a stripping layer between said temporary support and said ink-receiving layer.
• the web or sheet material to be used in step i. of said method comprises an ink-receiving layer coated from a solution of a non-cellulosic binder of which the pH is adjusted between 7.5 and 11.
• the web or sheet material to be used in step i. of said method comprises an ink-receiving layer that comprises a mordanting agent.
• the end-user who wishes to print any substrate with an ink-jet printing system and water-based inks, laminates a sheet or web material comprising at least three layers, viz. a temporary support, an ink-receiving layer and an adhesive layer with the adhesive layer onto the final substrate of his choice, strips away the temporary support to get a final substrate (with the form, colour, texture etc. of his choice) covered with an ink-receiving layer that enables printing in an ink-jet printing system with a water-based ink.
• composition of said three components of said sheet or web material has to be adjusted one to another so has to enable :

They include, e.g. those supports used in the manufacture of photographic films including cellulose triacetate, cellulose acetate propionate or cellulose acetate butyrate, polyesters such as poly(ethyleneterephthalate), polyamides, polycarbonates, polyimides, polyolefins, poly(vinyl acetals), polyethers and polysulfonamides.
• Polyester film supports and especially poly(ethylene terephthalate) are preferred as temporary support for the image-recording member according to the present invention, because of their excellent properties of dimensional stability.

It is therefore preferred to use poly(ethyleneterephthalate) films with a thickness between 40 and 100 ⁇ m as the temporary support for the sheet or web material according to the present invention, most preferably poly(ethyleneterephthalate) films with a thickness between 50 and 70 ⁇ m are used.

• the ink-receiving layer has a limited thickness.
• the ink-receiving layer, according to the present invention is too thick, the danger exists that, when laminating a sheet or web material comprising at least three layers, viz. a temporary support, an ink-receiving layer and an adhesive layer with the adhesive layer onto a final substrate with a certain relief pattern, said ink-receiving layer wipes out the relief pattern present on the final substrate. Therefore the thickness of said ink-receiving layer is preferably lower than 10 ⁇ m, and most preferably said thickness is between 3 ⁇ m and 7 ⁇ m.
