Definitions

  • the invention has for its object to treat paper and cardboard so that all types of systems containing an organic solvent, for example the dispersed or dissolved in an organic solvent printing ink, coating material or a varnish, especially a low-viscosity gravure ink as little as possible to punch or punch through the paper or cardboard.
  • an organic solvent for example the dispersed or dissolved in an organic solvent printing ink, coating material or a varnish
  • a low-viscosity gravure ink as little as possible to punch or punch through the paper or cardboard.
  • the less these colors penetrate the lower the consumption and the nicer the print gloss of the treated surface.
  • the color depth also increases.
  • This problem of knocking the printing ink into the paper is pronounced in all printing processes, but especially in gravure printing processes, since gravure printing inks have to have a significantly lower viscosity compared to other printing inks (high pressure, offset printing).
  • Gravure printing is one of the most widespread types of printing for all types of mass printing. For economic and postal reasons, there has been
  • the line of the coated varieties In order to have a good level of gravure ink on the paper surface, the line of the coated varieties must have a minimum thickness of about 6.5 - 7 g / m2 and page, for double-sided coated gravure paper this results in a coating at 50 g / m2 total weight.
  • Base paper of around 36 g / m2. From today's perspective, this is a lower limit, since it is only the fibers of the coating base paper that contribute to the physical strength values of the printing paper.
  • the uncoated rotogravure papers are neither in the whiteness nor in the gloss of those that can be produced Printed matter equivalent to coated gravure papers.
  • the consumption of gravure printing ink is about 2 1/2 to 3 times that of the coated paper, because the porosity and thus the absorbency of the gravure printing paper is much greater.
  • punching through and shining through the print on the back is a particular problem with these papers when the basis weight is further reduced.
  • EP-A-016 465 a process for the production of coated paper and cardboard is known, in which an aqueous coating slip with particles of at least one aqueous plastic dispersion and inorganic pigments is applied to the coating paper or cardboard and dried.
  • This coating slip should only penetrate to a small extent into the paper or the cardboard, thus preventing the coating slip from striking through and ensuring a smooth and trouble-free coating process.
  • Suitable quaternary organic ammonium salts are, in particular, those of the following formulas (1) to (8) wherein R is C8-C22-alkyl, C8-C22-alkenyl or a group of the formula- (AO) y -C8-C22-alkyl, R1 C1-C4-alkyl or benzyl, R2 is hydrogen, C1-C22-alkyl, C1- C22-alkenyl or a group of the formula - (AO) y -B or the formula - (AO) y -C8-C22-alkyl, R3 is hydrogen, C1-C4-alkyl or a group of the formula - (AO) y -B , A is C1-C4 alkylene, B is hydrogen or a group of the formula -COR, y is a number from 1 to 25 and X is an anion; wherein X, R, R1 and R2 have the meanings given above; where
  • Suitable organic amines for component Ic) are those amines on which the quaternary ammonium salts listed above are based. These amines have the following formulas (1 ⁇ ) to (8 ⁇ ), the individual substituents having the same meaning as in the formulas (1) to (8)
  • the compounds of the formula 1 are preferred. Also preferred are the partially neutralized amines of the formula 1 ⁇ in a mixture with C12-C18 fatty acids as component Ic).
  • substituents consist of C8-C22-alkyl or C8-C22-alkenyl groups
  • substituents consist of C8-C22-alkyl or C8-C22-alkenyl groups
  • groups which differ from natural fatty acids and their Derive mixtures such as tallow fatty acid, coconut fatty acid, oleic acid, palmitic acid, stearic acid.
  • Possible anions are, for example, chloride, bromide, sulfate, methosulfate, dimethophosphate, phosphate or anions of organic acids such as acetic acid, propionic acid, trichloroacetic acid, lactic acid, citric acid, tartaric acid, tartronic acid, oxalic acid, malonic acid.
  • the agent according to the invention preferably contains 15 to 25% by weight of the sum of the two components I and II.
  • the preferred quantitative ratios of the two components I and II to one another are 5 to 15% by weight for component I and accordingly 85 to 95% by weight .-% for component II.
  • Component Ib) preferably consists of 70% by weight of the quaternary ammonium salt and 30% by weight of the other portion (s). The same ratio is preferred for component Ic).
  • 0.05 to 0.5 mol, preferably 0.1 mol, of an acid per 1 mol of organic amine are used. Suitable acids for this purpose are the customary mineral acids and organic carboxylic acids.
  • component Ic) it has proven to be advantageous to use a non-ionic emulsifier. Instead of only one of the components Ia, b or c can also be used in various mixtures of these individual components.
  • Suitable polymers include, for example, polysaccharide derivatives containing anionic groups, such as e.g. Carboxymethyl cellulose, carboxymethyl starch, carboxymethyl guar, xanthan or polymers containing synthetic anionic or polar groups, e.g. Polyacrylates, anionic polyacrylamides, copolymers of acrylic acid and maleic anhydride, of styrene and maleic anhydride or of styrene and acrylic acid or also polyvinyl alcohols and polyvinyl acetates.
  • oxidized starch is preferred. Up to 70% by weight of these polymers can also be replaced by the white pigments commonly used in paper production, such as titanium dioxide, kaolin, calcium carbonate.
  • the claimed agents are produced by simply stirring the base batches of the required components.
  • the agent according to the invention can be added during the paper production in the mixing plant or material center and in an amount of 2 to 8, preferably 5 to 7% by weight, based on the finished paper.
  • the addition can in particular also take place within the filler slurry by first stirring the polymer into the filler slurry and then adding the quaternary organic ammonium compound. This mixture is then added to the fabric.
  • the agent according to the invention is preferably applied to the surface of the base paper. This is done with the help of suitable devices before calendering. If the paper machine is designed accordingly, the agent according to the invention can also be applied in the dryer section of the machine. After application to the surface, it is dried.
  • the order quantities for the order on the surface are generally 0.1 to 10 g / m2, preferably 0.6 to 3 g / m2.
  • the agent according to the invention is suitable for the treatment of all types of paper, such as are required in gravure printing, web offset printing, sheet-fed offset printing and letterpress printing.
  • the agent according to the invention is particularly interesting for gravure and web offset papers.
  • two types of paper are suitable for gravure printing, namely the highly filled, satin-coated, mostly wood-containing gravure printing paper in basis weights between 40 to about 80 g / m2 (SC paper) and the coated, wood-containing or wood-free, highly satined gravure printing paper in basis weights between 45 and approximately 135 g / m2.
  • Web offset printing is usually wood-containing uncoated or coated, so-called LWC paper with basis weights between 40 and 80 g / m2.
  • both wood-containing and wood-free papers with basis weights of 60 g / m 2 and up, which are sized or coated on the surface, are generally used.
  • the compounds according to the invention are also of interest for the treatment of paper for letterpress printing (letterpress printing, newspaper printing). It is particularly important here that papers which are treated with the agent according to the invention require less color when printing.
  • the organic groups in the quaternary ammonium salts and amines prevent further penetration of the printing ink by adsorption of the organic solvent or mineral oil contained in the printing inks and thus penetration of the back of the paper. At the same time, the affinity of the printing ink for paper is improved.
  • the use of the polymer such as oxidized starch is necessary because the organic quaternary ammonium salts alone exert a softening effect on the paper fibers and thus significantly reduce the tear length of the paper. This undesired effect of the quaternary ammonium compound is prevented by salt formation between the quaternary ammonium compound and the polymer. The softening effect and thus the reduction of the tear length is missing.
  • the advantages which can be achieved with the agent according to the invention on printing papers can be represented as follows: reduction of bleeding through and translucency, increase in color depth or blackness, reduced ink consumption, increase in gloss, reduction of missing dots, increase in conductivity. Web offset printing also showed an improvement in pick resistance.
  • the reduction in ink consumption also makes it easier to deink a paper treated with an agent according to the invention and then printed.
  • the fiber obtained during deinking has a much better whiteness.
  • the described agent also has advantages for carbonless carbonless papers that work with microcapsules. The problem with all of these capsule papers is that approximately half of the capsule content released is sucked back into the dispensing sheet and does not contribute to the color reaction at all. By treating the paper with the agent according to the invention, this sucking back of the capsule contents is reduced and the transfer factor is increased significantly.
