Definitions
- the invention relates to a recording material for the ink jet printing process with a substrate and an ink receiving layer which is applied to at least one side of the substrate, the ink receiving layer containing an amine-epichlorohydrin condensation product and an inorganic pigment.
- the invention further relates to a method using the new recording material for recording by the discontinuous ink jet printing method.
- Reaction products made on the basis of amine compounds and epihalohydrins are known as auxiliaries for the ink-receiving layers of ink-jet recording materials.
- JP-A-11 277 888 proposes an auxiliary with a linear cationic resin, which as a reaction product of an amine component containing a secondary amine, improves the water insensitivity of print images produced by means of ink jet printers and which should be distinguished by excellent print quality is formed with another amine component containing at least two amino groups and an epihalohydrin.
- JP-A-11 277 887 is also a water resistance-increasing aid with a structural formula of the linear cationic resin which is different from the above-discussed document and which has a comparable effect, but which, according to the description text, is expanded to reduce the so-called "ink bleeding"
- the viscosity of the 20% strength aqueous solution each containing the proposed aid is given as 50 to 500 mPa * s (B-type; 30 ° C.).
- JP-A-10 152 544 it is the object of JP-A-10 152 544 to provide an ink jet recording paper which allows only slight "ink bleeding" in printed images produced with aqueous inks and moreover enables a high color concentration and excellent water resistance of the printed images
- the object is to be achieved by adding to the coating composition in the form of a branched cationic resin which is present as a reaction product of ammonia with at least one preferably primary, secondary or tertiary amine and an epihalohydrin.
- Polyalkylene polyamine and alkanolamine are also preferred as the amine 10% what- The aqueous solution of this cationic resin is 1 to 30 m Pa.s, measured according to Brookfield (60 rpm / 25 ° C).
- JP-A-09 240 139 proposes the application of a branched cationic resin with the aim of presenting a production process for ink jet recording papers on which the color droplets of aqueous ink run little and on which printed images with high color density and excellent water resistance are made possible , which is formed as a reaction product of a polyalkylene polyamine with an epihalohydrin and optionally also with an aliphatic amine component.
- the viscosity of a 10% aqueous solution containing the proposed cationic resin is given as 30 m Pa * s, measured according to Brookfield (60 rpm / 25 ° C.).
- the excellent ink-jet recording property and the superior offset printability of a recording material with its particularly well-bonded surface are to be achieved, which moreover is characterized by high water resistance.
- the object is achieved with a linear cationic resin in the ink-receiving layer, examples of this cationic resin including Dimethylamine-epichlorohydrin polycondensation products are called.
- the ink-receiving layer also contains binders and optionally pigments.
- the document does not contain any indications of advantageous properties of the pigments in the ink-receiving layer. This document also does not disclose advantageous mixing ratios of the cationic resin to other constituents of the ink-receiving layer.
- EP-A-0 602 326 discloses a quaternary salt of a linear dimethyl laminate-epichlorohydrin adduct with a degree of polymerization between 2 and 2000 as a low molecular weight ink fixing agent in the recording layer of an ink jet recording paper.
- a (meth) acrylamide diallylamine In addition to increasing the ink fixability, copolymer should avoid color deviations in printed images.
- suitable inorganic and organic pigments are those whose particle size is in a range below 4 ⁇ m.
- pigment-based recording inks were hardly used in place of inks based on organic dyes, in particular acidic azo dyes.
- the problem with this type of recording ink is the low lightfastness of the organic dyes, combined with the problem of fading and discolouring printed images, which until now could only be solved unsatisfactorily by means of UV absorbers in the recording inks and by means of color stabilizers in the inkjet recording materials.
- the pigment-based recording inks which are now used more frequently are much more light-stable than the previously discussed inks based on organic dyes, but there is the problem of "ink bleeding" in the case of the recording inks based on pigments, among which the running of directly adjacent, differently colored printing patterns directly after one another
- the recording material according to the invention has been developed for use with pigment-based recording inks and significantly reduces the problem of "ink bleeding".
- the continuous process provides an ink jet ejected under pressure from a nozzle, which splits into very small droplets due to the surface tension at a certain distance from the nozzle.
- the droplets are electrically charged and then, depending on the print image to be generated, are either deflected into a collecting container by the electric field of electronically controlled deflection plates or placed on the recording material.
- the ink droplets are only generated depending on the print image to be produced and are ejected from a nozzle when an image point is to be generated on the recording material.
- This is a type of "drop-on.”
- -demand printer uses the piezoelectric effect in which an electrically controlled piezo element removes an ink droplet from the reservoir of the Separate the recording ink and eject this droplet from a nozzle.
- "BubbleJef" printers use an electrically controlled heating element that creates the smallest amounts of aqueous ink in a vapor bubble. The resulting vapor pressure expels the droplet.
- the invention relates to recording materials which can be used in both batch processes.
- the new recording material is to guarantee an excellent fixation of the applied inks and thus reduce the so-called "ink bleeding".
- the alignment of the new recording material with pigmented inks is intended to enable the printed images applied to be highly lightfast.
- pigmented inks are preferably used in poster printing and the posters created in this way are exposed to direct sunlight, for example as billboards, it is preferable to provide a new recording material that is characterized by great stability against any tendency to yellowing. Finally, the recording material is intended to ensure an acceptable wet-wipe resistance of printed images.
- the inventors recognized that the object was achieved by a recording material for the ink jet printing process with a substrate and an ink receiving layer applied to at least one side of the substrate, the ink receiving layer being an amine-epichlorohydrin condensation product as well contains an inorganic pigment, characterized in that
- the ink receiving layer has at least one ink fixing agent which consists of a medium-molecular branched amine-epichlorohydrin condensation product,
- the inorganic pigment is at least 80% by weight with a particle size in a range between 6 and 12 ⁇ m and
- the ink fixative pigment ratio is in a range of 1: 2 to 1: 6.
- the amine-epichlorohydrin condensation product is of medium molecular weight, provided that as a 10% strength aqueous solution it has a viscosity in a range from 20 mPas to 50 mPas. The aforementioned viscosity is determined according to Brookfield (spindle 1/100 rpm / 25 ° C).
- the basis of the invention is the choice of the amine-epichlorohydrin condensation product as at least one ink fixing agent, which is optionally integrated into the ink receiving layer together with other ink fixing agents. It is essential to the invention that the amine-epichlorohydrin condensation product is in a medium molecular branched form. Other versions of the amine-epichlorohydrin condensation product have proven unsuitable for various reasons; for example, the use of a low molecular weight, unbranched amine-epichlorohydrin condensation product is forbidden, because recording materials containing it have an excessive odor formation due to the free amine.
- the inventors also recognized that the ink fixer-pigment ratio must be in a range of 1: 2 to 1: 6 based on the weight percent of pigment and ink fixer in the ink-receiving layer, with the weight percent on all ink-fixers incorporated in the ink-receiving layer or obtain pigments.
- the object on which the invention is based can, however, only be achieved completely and convincingly if, at the same time as the features set out above, the inorganic pigment is at least 80% by weight with a particle size in a range between 6 and 12 ⁇ m is present, determined as a D50 value (Malvern - that is, the determination is made according to the pigment manufacturer's instructions using a laser measuring device from Malvern, type Master-Sizer S).
- the ink fixative-pigment ratio of 1: 2 to 1: 6 according to the invention is limited on the one hand by an increasingly decreasing wet wipe resistance, which is no longer acceptable with larger amounts of ink fixative beyond an ink fixative-pigment ratio of 1: 2, and on the other hand by an increasingly deteriorating "ink bleeding" behavior, which can be rejected as convincing for smaller amounts of ink fixative beyond an ink fixative-pigment ratio of 1: 6.
- the inventors recognized that the novel recording material had particularly good properties when the ink fixative-pigment ratio was in a range from 1: 3 to 1: 5.5 inclusive, based on the weight percent of Pigment and ink fixer in the ink-receiving layer - lies, with the weight percent again relating to all ink fixers or pigments incorporated in the ink-receiving layer.
- the ink-receiving layer of the recording material according to the invention comprises a proportion of binder and co-binder in a range from 10 to 55% by weight.
- Aqueous polymer dispersions of ethylene-vinyl acetate and in particular styrene-butadiene latex, polyacrylates and solutions of partially or completely saponified polyvinyl alcohol, which are used alone or in combination, have proven particularly useful.
- the pigment content of the ink-receiving layer of the recording material according to the invention is in a range between 30 and 70% by weight. It is preferred if the inorganic pigment is at least 80% by weight with a particle size in a range between 6 and 12 ⁇ m, determined as the D50 value (Malvern). Aluminum hydroxide, silica (acid) gel and precipitated silica have proven particularly effective. The three last-mentioned pigments can each be modified with aluminum or with aluminum oxide, as well as unmodified. It is possible that the ink receiving layer as the ink fixing agent has only a medium molecular branched amine-epichlorohydrin condensation product.
- the simultaneous use of further ink fixing agents in addition to the medium-molecular branched amine-epichlorohydrin condensation product is also possible, whereby - without being limited to this - one or more of the following compounds selected from polydiallyl-dimethyl-ammonium chloride , cationic polyacrylamides, cationic polyacrylates, polyvinylamines, polyethyleneimine and polydicyandiamides, provided that these additional ink fixing agents are present in a quantity not exceeding 30% by weight, in particular in an amount not exceeding 10% by weight, based on the total amount of the ink fixing agent.
- the total proportion of ink fixing agent in the ink-receiving layer is in a range between 5 and 30% by weight, preferably in a range between 5 and 20% by weight, this total proportion being part of the application of ink-receiving layers high area-related mass within the above range tends to be chosen towards the lower limit.
- Other components such as, for example, sodium hydroxide solution, optical brighteners and defoamers, are added as necessary and make up up to 5% by weight of the ink-receiving layer, the individual proportions in the ink-receiving layer adding up to 100% by weight ,
- the area-related mass of the ink-receiving layer should not be chosen too low, since otherwise the wet smear resistance will decrease too much and the “ink bleeding” can be reduced too little.
- the area-related mass is up the ink receiving layer is primarily limited from an economic point of view.
- the ink-receiving layer in two layers positioned one above the other, a lower layer being connected to the substrate or to a preparation layer applied to the substrate in accordance with a preferred embodiment, while an upper layer is applied to the lower layer .
- Particularly good results can be achieved if the first layer has a mass per unit area between 4 and 12 g / m 2 , preferably between 6 and 8 g / m 2 , and the second layer prefers a mass per unit area between 2 and 10 g / m 2 has between 4 and 6 g / m 2 .
- the two layers also have the same auxiliary components in accordance with the disclosures to be found in this document. If the ink-receiving layer is only formed as a single layer, a mass per unit area of this layer of between 4 and 15 g / m 2 is recommended, a range between 5 and 10 g / m 2 and very particularly a range between 7 and 9 g / m 2 being particularly preferred ,
- At least one preparation layer is arranged between the substrate and the single or, in a preferred embodiment, the first layer of the ink-receiving layer, which preferably has a mass per unit area in a range from 0.1 to 2.0 g / m 2 .
- the preparation layer can be designed as a simple application of starch.
- the recording material according to the invention comprises, on the side opposite to the side with the ink-receiving layer, a backside coating which can be designed as an ink-receiving layer or as a simple starch application.
- a starch application it is used to ensure good grip so that there are no transport problems in the inkjet printers. With the help of a simple application of starch, improved printability can be achieved, particularly in the offset printing process.
- the starch application designed as a back coating preferably has a mass per unit area in a range from 0.1 to 2.0 g / m 2 .
- the substrate is a paper web.
- the invention further encompasses a method of discontinuous ink jet recording using a pigment based recording ink and a recording material.
- the recording material comprises a substrate and an ink-receiving layer which is applied to at least one side of the substrate, the ink-receiving layer containing an amine-epichlorohydrin condensation product and an inorganic pigment, and wherein
- the ink receiving layer has at least one ink fixing agent which consists of a medium-molecular branched amine-epichlorohydrin condensation product, •
- the inorganic pigment is at least 80% by weight with a particle size in a range between 6 and 12 ⁇ m and
- the ink fixative pigment ratio is in a range of 1: 2 to 1: 6.
- the invention also encompasses a method for recording according to the discontinuous inkjet printing method with a recording ink based on pigment and with a recording material according to the invention, which can be designed according to one of the further embodiments described above.
- the new process provides for the printing of the new recording material with "drop-on-demand” printers, which either use the piezoelectric effect or, as a "bubble jet” printer, use an electrically controlled heating element to eject the smallest droplets of ink.
- a paper web is produced from bleached and ground hardwood and coniferous cellulose pulps with the addition of conventional admixtures in usual quantities with a mass per unit area of 82 g / m 2 .
- the paper web is given a starch preparation of 0.3 g / m 2
- a starch preparation of 1 g / m 2 is applied.
- a medium-molecular branched amine-epichlorohydrin condensation product is used as the ink fixative in the coating slip of Example 1.
- the coating slip according to Comparative Example 2 has otherwise identical components instead of Amine-epichlorohydrin condensation product a polydiallyl-dimethyl-ammonium chloride.
- the coating slips are applied to the front of the paper web described above in its production at 8.5 g / m 2 . In this way, a sample of example 1 according to the invention and comparative example 2 is produced.
- Ink fixative B medium molecular weight, not branched (36.5 m Pa * s)
- Ink fixative C medium molecular weight, branched (35 m Pa * s)
- the numbers in parentheses in the above list of the ink fixatives represent the viscosity of the amine-epichlorohydrin condensation product as a 10% strength aqueous solution, measured according to Brookfield (spindle 1/100 rpm / 25 ° C.).

- the coating slips are applied to the paper web described above in their manufacture.
- the ink fixing agent-pigment ratio was varied.
- the samples produced in this way are to be examined with regard to their “ink bleeding” behavior and the wet smudge resistance of printed images applied.
- the printed images are drizzled with water. After a contact time of 2 seconds, wipe a finger several times under constant pressure over the printed image.
- the printed image should be as possible little, ideally not to be blurred at all.
- Example 15 and example 16 in order to reduce the proportion of ink fixative - based on 500 parts by weight (lutro) of basic formulation 2 - a smaller amount of ink fixative and thus a larger amount of all other components are introduced into a container with constant stirring.
- Example 17 according to the invention and Comparative Example 18 a larger one is used to increase the proportion of ink fixative - based on 500 parts by weight (lutro) of basic formulation 2 Amount of ink fixative and thus a smaller amount of all other components entered into a container with constant stirring.
- Table 2 shows the ink-fixant-pigment ratios set and the visually assessed “ink-bleeding" behavior of the samples and the wet-wipe resistance of the printed images. Examples according to the invention are again identified by “EB” and comparative examples by “VB”:
- the examples according to the invention illustrate particularly clearly that the recording material according to the invention has succeeded convincingly in providing an inexpensive recording material for the inkjet printing process which guarantees an excellent fixation of the applied inks, in particular when printed with pigment-based recording inks, and thus the so-called “ Ink-bleeding "is reduced, which is not the case with the comparative examples.
