Definitions
- the invention relates to a printable composition comprising superabsorbent polymer particles, at least one binder, at least one additive and at least one organic solvent.
- the invention further relates to sheet-like materials which are printed on at least one surface with the printable composition and the use of the printed sheet materials for liquid absorption and / or liquid delivery.
- a printable formulation of a superabsorbent polymer is known from DE 195 21 431. It is a two-component swelling paste comprising an aqueous, slightly crosslinked polyacrylic acid and a reactive crosslinker. After joining the two components, the mixture becomes increasingly viscous and must be applied to the materials to be printed within a few hours. This happens e.g. by printing or knife coating on textiles or fabrics such as paper or foils, whereby by means of stencil a uniform pattern can be achieved. Subsequently, the applied polymer must be crosslinked by a thermal treatment.
- Disadvantages of the printable composition described in DE 195 21 431 are that after mixing the two components, only a limited time is available for processing the printable composition and that the crosslinking to the superabsorbent polymer continues during and after the printing process, thereby no polymer particles of defined size can be produced.
- Another disadvantage is the use of an aqueous system which causes swelling of the superabsorbent polymer.
- DE 196 52 762 describes a superabsorbent thermoplastic composition comprising superabsorbent, a binder and, as an additive, a component which is soluble in water.
- the composition contains no solvent.
- This superabsorbent thermoplastic composition is used to make waterproof construction, particularly longitudinally watertight cable constructions.
- a disadvantage of this superabsorbent thermoplastic composition is that it is in a liquid state only at temperatures of 140 to 160 ° C and therefore is not suitable for use in a printing process.
- EP 0 188 959 discloses a composition suitable for coating comprising superabsorbent polymer particles, a water-soluble binder, various additives and an organic solvent, preferably methanol or ethanol. The composition is applied by doctoring onto materials such as textiles, paper or plastic.

- the aqueous solution containing the cellulose ethers and the fixing agent is applied to the fiber materials by spraying, immersion or brushing, followed by fixation by heating.
- a detachment of the absorbent layer upon ingestion of water is prevented according to DE 2 441 781 by fixation by means of binders.
- a disadvantage is the use of aqueous solutions, which leads to swelling of the cellulose ethers already during the production of the absorbent fiber materials.
- DE 195 05 708 discloses sheet-like, superabsorbent materials which comprise at least one superabsorbent polymer and at least one water-soluble polymer formed as a planar matrix.
- the superabsorbent polymer is not contained in a printable composition, but a viscous solution of the water-soluble polymer is first applied to a surface and this is then sprinkled with the superabsorbent polymer. In the subsequent drying can lead to chemical or physical bonds between the water-soluble matrix material and the superabsorbent polymer.
- the superabsorbent polymer may additionally be fixed by treatment with an embossing roller.
- WO 00/64311 describes a hydrophilic, flat material consisting of a matrix in the form of a mesh with individual fibers or an open-pored plastic foam and a superabsorber grafted onto the matrix.

- the object is further achieved by printed sheet materials which are printed on at least one surface with the printable composition. Furthermore, the object is achieved by the use of the printed sheet materials for packaging food, for packaging moisture-sensitive goods, for moisture control in rooms or as a membrane in textiles.
- a composition which can be applied to sheet-like materials by means of conventional printing processes is referred to as "printable".
- the printing ability of the composition according to the present invention is determined in particular by the viscosity. If the viscosity is too low, the composition will run out of the wells of the roll during the gravure process. If it is too high, the composition will not be completely transferred to the sheet material.
- superabsorbent refers to the property of hydrophilic materials to absorb large amounts of water or aqueous liquids and to hold them under pressure even without being dissolved immediately.

- the printable composition of the invention containing superabsorbent polymers offers the following advantages over the prior art. Due to a suitable viscosity, the composition can be easily, quickly and economically printed onto sheet materials by conventional printing techniques. It is also possible to print only limited areas. Due to the organic, water-insoluble binder in combination with the additive, the superabsorbent Bing polymer particles both in the printed layer and fixed with this layer on the sheet material. This fixation and the water insolubility of the binder prevents the detachment of the print layer from the substrate even when larger amounts of water or aqueous liquids are absorbed, thereby ensuring reversible absorption and / or release of aqueous liquids. The use of an organic solvent prevents swelling of the superabsorbent polymer particles in the printable composition prior to printing on the sheet materials.
- the solids content of the composition is from 20 to 50% by weight.
- coating weights amounts of firmly transferable printable composition of from 1 to at least 30 g / m 2 can be achieved hereby.
- the printable composition may contain any superabsorbent polymer particles.

- the choice of the binder or binders for the printable composition depends on the required field of application of the sheet-like materials printed with the superabsorbent composition. For example, when using the printed sheet materials in the food industry, the binder must be suitable for food. This condition is met, inter alia, by special vinyl chloride copolymers or vinylbutyralcopolymers used for direct food contact.
- the printable composition contains as additive or additives plasticizer.
- plasticizers are selected in the industry. Examples of Suitable plasticizers include acetyltributyl citrate, adipate plasticizers, phthalate plasticizers and epoxidized soybean oils. Other additives such as waxes and leveling agents may also be included in the printing composition. Like the binders, these additives are also used for paint production.
- the mentioned plasticizers are hardly volatile organic liquids. They serve to keep the printed on the sheet materials layer consisting of the printable composition elastic and to prevent embrittlement.
- Leveling agents are used to ensure a high flatness of the printed with the inventive printable composition sheet materials.
- bleed disturbances of a printed surface e.g. the paint composition, the drying process, temperature and ventilation and film formation.
- the most common form of flow disturbance is the so-called orange peel effect, which is caused by a surface structure with dimensions of 0.2 to 10 mm.
- leveling assistants are Butylglycolacetate, butyl triglycol, Depanol ', which is a mixture of different p-menthadienes, Depanol N IV ®, which is a mixture of monoterpene hydrocarbons with oxygen containing terpene derivatives, acetic sigsärebutylester such as acetic acid-n-butyl ester, Isobutyl acetate and 1-methylpropyl acetate, 2-ethoxyethyl acetate, ethyl diglycol, ethyl glycol, isononanol, mesityl oxide, 1-methoxy-2-propanol-acetate, methyl butanols such as amyl alcohol and 3-methyl-1-butanol, methyl diglycol, methyl glycol, propylene glycol 1-ethyl ether and propylene glycol-1-methyl ether.
