Definitions

  • the present invention relates to a coating composition in particular for sheet-fed lithographic offset printing paper, as well as to a paper coated with such a coating, and to methods for applying such a coating to a substrate.
  • wood-free coated fine paper is in the field of sheet-fed lithographic offset printing processes. There is a clear trend in this market towards shorter times to re-print and for converting in order to reduce the time of the production process and to facilitate handling.
  • Printers will have a clear advantage when paper can be almost instantly re-printed and converted (i.e. within 0.5 hours) as this is leading to a much higher efficiency of the process.
  • Workflow in the printing industry today has been fully digitized, enabling same-day processing of a complete print-job (like e.g. CD-inserts), provided that the print-process in itself would enable to do so.
  • the only component in the complete workflow that prevents speeding up of the full process is the interaction ink-paper, i.e. sufficient drying before converting.
  • ink drying time is the bottleneck or the rate determining step in the full sheet-fed lithographic offset printing process.
  • the shorter time to converting requires both an adequate physical drying component as well as a sufficient (but not necessarily 100% completed) chemical drying component of printed ink.
  • the physical drying component can e.g. be increased by adjustment of the porosity and/or of the surface energy of coating layers in a way that:
  • An induction period with respect to initial ink setting is necessary to avoid runnability problems on the press and to avoid loss in quality of the printed surface. Adjustment of surface energy appears also to be necessary to obtain superior print quality.
  • the quickset inks involved in general are mainly composed of ink colour pigment, resin, drying oil (which is a vegetable or biological oil) and a high boiling hydrocarbon (mineral) solvent (e.g. for adjusting the total flow characteristics).
  • ink colour pigment which is a vegetable or biological oil
  • drying oil which is a vegetable or biological oil
  • a high boiling hydrocarbon (mineral) solvent e.g. for adjusting the total flow characteristics.
  • such 'set' ink film is sufficiently rigid to withstand limited mechanical forces and enables the sheet to be re-printed on the second side of the sheet very soon after completing the first side.
  • its rigidity usually has not well developed enough for 'safe' instantaneous further handling or converting (e.g. folding, cutting) of the printed paper without damaging printed images. In fact several hours up to a day or more might be needed before these next converting steps can be performed. In order to keep printing process economics viable, it is essential for printers to have this interval time minimised.
  • a well-known present method is to start up an additional chemical drying step of the printed ink layer, a so-called oxidative polymerisation or cross-linking reaction.
  • Both the vegetable drying oil part, e.g. linseed oil and the resin part are partly based upon (preferentially conjugated) unsaturated fatty acids.
  • Oxygen in the air adds to the double bonds of these fatty acids and resins to initially form hydroperoxides. After consecutive degradation of these hydroperoxides the resulting free radicals are very reactive. These radicals attack other fatty acid molecules and attach, forming new (larger) free radicals. This causes polymerisation to finally form a cross-linked ink network.
  • the rate-determining step, formation and degradation of hydroperoxides can appreciably be speeded up by the presence of special catalytic species (so-called primary/secondary/auxiliary driers or siccatives) in the ink.
  • catalytic species such as primary/secondary/auxiliary driers or siccatives
  • fatty acid salts e.g. naphtenates or octoates
  • transition type metals like cobalt
  • the present regular working method of printers therefore is to add so-called drier systems to the ink prior to the printing to speed up chemical drying.
  • This has several drawbacks. For instance a practical point is the appreciable reduction of the so-called 'open time' of the ink system, requesting a printer to clean-up the printing machine at the end of every regular 8h working day cycle, or toxic anti-skinning agents like e.g. oximes have to be added to the ink.
  • Another drawback is that a printer is forced to deal not only with standard ink but also to use several types of (more expensive) printing inks with an added drier system, depending on the absorptive and other printing properties of respective paper qualities.
  • the objective problem underlying the present invention is therefore to provide improvements for the printing process, in particular improvements allowing to reduce the time which has to be waited until the printed sheet-fed paper can be further treated or converted.
  • the present invention solves the above problem by providing a coating for an offset paper comprising a catalyst system for fixing polymerizable or crosslinkable constituents of the offset ink.
  • catalyst system shall be understood a system comprising one or several (as a mixture) catalyts or catalytically active components including additives, ligands, salts etc. supporting the total activity of the catalyst system.
  • the object of the present invention is therefore a coating according to claim 1, a paper according to claim 26, a method according to claim 28 as well as a use according to claim 30.
  • the key feature of the invention is therefore the fact that surprisingly it is possible to incorporate in particular water-dispersible or water-soluble catalytic primary drier systems, preferentially combined with a well-balanced ligand/chelate system, into the top coat layer (or also or in the alternative into a middle coating, e.g. in order to hide sometimes possibly slightly coloured catalyst systems behind the top coat) of for example a wood free coated grade for sheet-fed offset.
  • a middle coating e.g. in order to hide sometimes possibly slightly coloured catalyst systems behind the top coat
  • the catalyst catalyzes the oxidative polymerisation or the crosslinking of unsaturated constituents of offset ink printed onto the coating.
  • the catalyst fixes fatty acid and resin parts of the offset ink.
  • the drying time of offset printing ink applied to such a coating can be reduced below 2h, even below 1h, and in some cases to values equal or below 0.5h.
  • the catalyst is a transition metal complex, wherein preferentially the metal ion of the transition metal complex is selected from the group of Ti, V, Cr, Mn, Fe, Co, Ce, Cu, or a mixture thereof.
  • primary drier catalysts which are based on a transition metal selected from the group of Mn, V, Fe or a mixture thereof, wherein in particular Mn alone proved to be particularly powerful and efficient.
  • secondary driers which are additionally present.
  • Such secondary driers can be based on Pb, Bi, Ba, Al, Sr, Zr e.g. in ionic form as salts, complexes or the like.
  • auxiliary driers are additionally added like e.g. Ca, Zn, Li, K, again in ionic form as salts, complexes or the like.
  • the transition metal complex which is used as the catalyst is a carboxylate and/or a naphthenate complex.
  • carboxylates with an alkyl chain of 2-18 carbon atoms, preferably of 6-12 carbon atoms, which may be unsubstituted or substituted can be shown to be efficient.
  • a particularly suitable system is a 2-ethylhexanoate-complex, in particular a Mn 2-ethylhexanoate-complex.
  • the naphthenic acid anion has an alkyl chain of 1-12 carbon atoms, preferably of 4-8 carbon atoms, and the alkyl chain as well as the cyclopentane unit may be unsubstituted or substituted.
  • the transition metal complex used as the catalyst comprises or is supplemented by at least one bidentate ligand.
  • a bidentate ligand can advantageously be used in combination with the above-mentioned carboxylate or naphthenate ligand system.
  • Particularly useful are bidentate systems which lead to chelate-rings with e.g. 5 atoms.
  • the atoms which are used for providing the link to the metal atom may be selected from the group N, O, S, and/or P or combinations thereof. Therefore, useful bidentate systems include organic molecules with appropriate sp3 or sp2 hybridised N-atoms and/or O-atoms which are available for forming a bond to the metal atom.
  • ligands in the form of a diamine or alkanolamines like for example selected from the group 2,2'-bipyridine, 2-aminomethylpyridine, 2-hydroxymethylpyridine, or 1,10 phenanthroline, which may be substituted or unsubstituted.
  • the ligands are preferably substituted by side groups, which increase the stability and/or increase the solubility or dispersibility of the catalyst system in water, which is important since coatings are deposited onto a substrate on a water basis.
  • a particularly suitable system is given by a catalyst consisting of or comprising a Mn 2,2'-bipyridine system, in which e.g. Mn is present as a salt complex and additionally bpy is present, typically in slight molar excess.
  • Mn is present as a salt complex and additionally bpy is present, typically in slight molar excess.
  • a system can be provided as a combined system with a Mn carboxylate or a Mn naphthenate, suitable is for example a combination of Mn 2-ethylhexanoate with (Mn) 2,2'-bipyridine.
  • the catalyst i.e. the metal part of the primary drier complex
  • the catalyst is present in the coating in 0.01 - 0.5 weight-% of the total dry weight of the top paper coating, preferably in 0.05-0.2 weight-% of the total dry weight of the coating.
  • the transition metal complex preferentially comprises at least one bidentate ligand and the ratio of metal to ligand is in the range of 1:1 - 1:8.
  • additives for increasing the solubility/dispersibility of the transition metal complex and the ligands present can e.g. be chosen from alcohols or glycol-ethers like e.g. 1-methoxy-2-propanol or propylene-glycol-monomethyl-ether. Those additives can either be added to the coating formulation or they can be added to the solution/dispersion of the transition metal complex prior to its introduction into the coating formulation.
  • the present concept can be applied to any (aqueous) coating formulation. It however proves to be advantageous if the coating has a high degree of porosity and an appropriate morphology of the porosity and/or appropriate surface energy of pore walls.
  • the coating comprises 100 parts in dry weight of pigment substantially supplemented by 5-20 parts in dry weight binder and additives like lubricants, thickener etc., wherein the pigment part comprises ultra-fine CaCO 3 and/or kaolin or clay wherein up to 10-20 parts may be substituted by synthetic solid or vacuolated polymeric pigments which may e.g.
  • SMA Styrene maleic acid copolymeric latexes
  • SMI styrene malimide copolymeric latexes
  • the catalyst is only added to the top coating, it may however also be added to layers which are beneath the top coat.
  • the top coat comprising the catalyst system typically has a thickness in the range of 10-30g/m 2 , preferably in the range of 10-15 g/m 2 .
  • the present invention additionally pertains to a paper coated with a coating as given above, preferentially as a top coat.
  • Beneath such a top coat there is preferably an additional coating, which in particular supports the physical absorption process of the ink in the layers structure.
  • Possible is a formulation of the additional middle coating as follows: 100 parts in dry weight fine CaCO 3 ; 5-10 parts styrene butadiene synthetic binder; 1 part lubricant; 1 part modified starch; 1 part PVA; 1 part CMC.
  • the present invention relates to a method for the production of a coating as given above, wherein the transition metal complex is added, preferentially as an aqueous solution or dispersion, to a stirred coating formulation, and the final coating formulation is coated onto a paper substrate.
  • the coating process can be carried out using regular techniques like a blade coater, a roll coater, a spray coater, a curtain coater or other coater systems, and the paper may be calendered after the coating process.
  • a chelating agent preferably in excess to the transition metal content (on a molar basis) is added to the coating formulation, wherein the chelating agent is added as an aqueous solution or dispersion and may contain one or several additives (cosolvents using the sulubilization principle) to increase the solubility/dispersibility or to increase the stability of the catalyst system.
  • the present invention relates to the use of a catalyst for fixing polymerizable or crosslinkable constituents of the offset ink as an additive for a coating.
