Definitions

• the present invention relates to a printing medium which for Use for printing with inks is suitable.
• the Registration a print medium for inkjet printers, which prints with high quality allowed at low cost.
• EP-A-736 392 describes a printing medium which is based on a base material has a porous, ink-receiving layer, which made of alumina hydrate with a boehmite structure and a binder is composed.
• a similar medium is described in EP-A-749 845 described, the ink-receiving layer by the pore size is defined.
• EP-A-655 346 there is an ink jet recording sheet described which coated a carrier and one thereon Ink receiving layer comprises, said ink receiving layer mainly from non-spherical, cationic, colloidal Silicon dioxide is composed.
• the definition of the invention is open to coating.
• the surface layer contains in the preferred embodiments, a binder e.g. from a optionally modified polyvinyl alcohol or similar products consists. In the examples are compositions with such binders and optionally cationic resins (for the fixation of pigments) disclosed.
• inorganic brine such as colloidal Silicon dioxide, aluminum oxide, zirconium oxide, yttrium oxide or mixtures of which, in the form of sols together with silanols (obtained by hydrolysis corresponding mono-, di- or trialkoxysilanes) or others Reaction products of silanes, optionally with functional Groups are provided, are suitable for recording media for the To produce inkjet printing.
• Brines are colloidal liquids in which there are inorganic particles in the size of 5 - 200 nm.
• a combination of colloidal acidic or basic Silicon dioxide solutions and silanes, possibly with functional Groups have been provided for the production of Coating agents used, for example metal articles, Plastic etc. have a high surface hardness and a high chemical Give resistance.
• compositions have not yet been used for coating a recording medium for ink jet printing suggested.
• the subject of the present application is accordingly a medium for inkjet printers as defined in the claim section.
• Another subject is a manufacturing process for such media.
• Colloidal solutions such as brine from silicon dioxide, zirconium dioxide or yttrium oxide, are offered commercially ready for use.
• Typical SiO 2 products are KLEBOSOL® (ciostowne Hoechst FR) and LEVASIL® (Bayer DE).
• aqueous SiO 2 / Al 2 O 3 dispersions AEROSIL® (Degussa-Hüls AG DE), metal oxide sols (Al 2 O 3 , cerium oxide, zinc oxide, SiO 2 , tin oxide doped with Sb, tin oxide, yttrium oxide, zirconium oxide, particle size 5-10 nm), NYACOL® (Nyacol Products, Ashland MA US).
• one or two of the silicon-functional groups X can be replaced by lower alkyl, such as CH 3 , resulting in products with one or two mono- or difunctional silicon-functional groups.
• the silane is adjusted to a suitable pH, for example to pH 3-4, using concentrated formic acid.
• a coating composition for the Use in the present invention is preferably an aqueous one colloidal silicon dioxide dispersion to a silane, e.g. to a trialkoxysilane, given.
• the silane is at least partially hydrolyzed.
• the solution obtained is then applied to the support, for example using a dipper.
• the applied medium is then dried at an elevated temperature, a medium for inkjet printing being obtained.
• Inkjet media produced in this way have excellent properties: the applied ink is immediately dry, does not cause sticking, has a good gloss and is waterproof.
• the ratio of a sol of SiO 2 and / or Al 2 O 3 to the silane can be 1: 1 to 1:50 (solid to solid or based on the active content), preferably 1: 5 to 1:15, particularly preferably 1:10 .
• organic or inorganic pigments can also be added to the sols.
• a typical example of an organic pigment is Antara (emulsion of a copolymer of styrene and vinypyrrolidone from ISP, New Jersey, US), while various metal oxides can be used as inorganic pigments.
• the carrier material for the printing medium can be paper, coated paper (one or more absorbent layers, barrier layer, polyethylene layer, etc.), a woven or non-woven textile layer or a film made of plastic, such as polyester, vinyl, etc.
• the coating solution can additionally contain polymers, polymer dispersions, plasticizers, organic or inorganic fixatives for dyes and color pigments, optical brighteners, wetting agents, antifade additives, catalysts or crosslinking agents.
• the medium is usually dried at one Temperature in the range of 70 to 150 ° C, preferably at one temperature of 90 ° C. Drying can take place in a drying cabinet in the laboratory.
• test images used in the examples below were taken with a commercially available printer "EPSON Stylus Photo” printed out, the print according to the settings “Glossy Film” or “Glossy Paper” was varied.
• the base paper (MultiCopy Stora 90 g / m 2 ) was not treated.
• KLEBOSOL 30H50 was applied to BURGO with a 08 mm Meierstick Glossy paper applied.
• the TESLIN film (Teslin 110 g / m 2 , PPG Industries Inc.) was not treated.
• Example 1 10 g SYLYSIA 435 dispersion (20% pigment in distilled water, dispersed for 5 min with an Ultra-Turrax turbine) and 10 g MOWIOL 28-99 solution (10% dissolved in distilled water) were mixed. Two layers of 10 g / m 2 were applied dry to the BURGO glossy paper with a 08 mm Meier stick. The coating composition of Example 1 was applied dry to this base layer, 20 g / m 2 , using a 04 mm Meier rod, 7 g / m 2 .
