Definitions
- This invention belongs to the field of printing inks. More specifically, it is related to printing inks containing volatile substances and which are to be used in the method of engraved steel die printing for the printing of security documents such as checks, shares, airline tickets, banknotes, etc.
- intaglio printing comprises the use of printing ink carrying surfaces, typically printing cylinders or printing plates, where the pattern to be printed is engraved and the engravings are filled with printing ink to be transferred to the printing substrate in order to create the document.
- intaglio printing shall only define as the engraved steel die printing process where chromium plated, engraved steel or nickel plates or cylinders are used, and shall not include the well known rotogravure or gravure printing process.
- this invention does not relate to low viscous printing inks for the conventional gravure printing where a totally different concept of ink formulation is necessary. It is rather related to printing inks in paste form for engraved steel die printing.
- a rotating engraved steel cylinder is supplied with ink by one or more template inking cylinders by which a pattern of inks of different colour is transferred to the printing cylinder. Any excess of ink on the plain surface of the printing cylinder is then wiped off by a rotating wiper cylinder covered by a plastisol, using diluted aqueous sodium hydroxide as an emulsifying medium for the wiped-off excess ink, or a paper/calico wiping device. Then, the printing pattern in the engravings of the printing cylinder is transferred, under a pressure up to about 500 bars, on the substrate to be printed which may be paper or plastic material in sheet or web form.
- Film forming characteristics allowing further manipulation of sheets or webs carrying printed films of up to 200 microns thickness 24 hours after printing or respectively immediately after printing.
- a conventional engraved steel die printing ink for security documents has the following composition, all percentages being by weight and referring to the total of the inks:
- extenders such as CaCO 3 , BaSO 4 , TiO 2 , aluminium silicates
- the volatile organic solvents used are typically mixtures of mineral oils (hydrocarbons) having a boiling range of from about 180° to about 300° C., and low molecular glycol ethers.
- U.S. Pat. No. 4,764,215 suggests to incorporate into a conventional water-wipe intaglio ink a drying oil soap, namely the combination of a metal hydroxide, a hydroxyamine such as triethanol amine, .[.are.]. .Iadd.and .Iaddend.a drying oil.
- a drying oil soap namely the combination of a metal hydroxide, a hydroxyamine such as triethanol amine, .[.are.]. .Iadd.and .Iaddend.a drying oil.
- the drying oil soaps are metal soaps of unsaturated fatty acids stabilized against micelle formation by the hydroxyamine. It is certain that these soaps are low molecular compounds or compositions.
- solvents can often not or not fully be recovered from the exhaust air streams which are emitted from the printing/dryer installations.
- Environmental air and also the air in the printing houses are thus contaminated by solvent vapours.
- the solvents typically used in engraved steel die printing such as high-boiling mineral oils, glycol ethers, etc., are considered to be dangerous for the human health.
- Another object of the invention is to provide engraved steel die printing inks which do not contain more than about 15% and even less than 12% by weight of volatile organic solvents.
- Still another object of this invention is to provide engraved steel die printing inks for the printing of security documents which fulfill all requirements regarding the processability and the printing results which are characteristic for organic solvent-based inks.
- Another object of the invention is to provide engraved steel die printing inks which can perfectly be emulsified in even weaker solutions of caustic soda or even in pure water.
- the invention which, in its broadest aspect, is characterized by the fact that the amount of volatile organic solvents in the printing ink is reduced to about 15% by weight or less, referred to the total weight of the ink, typically but not necessarily by the introduction of water.
- the printing ink of this invention contemplates compositions wherein the solvent concentration, compared to the inks presently available, is reduced. This solvent reduction may be achieved as such, i.e. in incorporating less solvent than before into a printing ink or in replacing part of the amount of organic solvent normally used in known inks by water, or by the combination of these two features.
- the film forming reactions allowing the achievement of this mandatory loss of hydrophilic properties, in order to assure the required chemical resistance of the final prints, are oxypolymerisation, interpolymer neutralisation and formation of three dimensional interpenetrating networks.
- These macromolecular surfactants can be obtained by polymerisation, polyaddition or polycondensation reactions. Their synthesis is well known in the art and does not belong to this invention.
- the hydrophilic macromolecular surfactants to be used according to this invention are nonionic, anionic or cationic as well as zwitterionic ones.
- the functional groups attached to these macromolecules are for example carboxylic or sulfonic acid groups, hydroxyl groups, ether groups or primary, secondary, tertiary or quaternary amino groups.
- the acid groups may be neutralized with amines, alkanolamines or preferably inorganic bases, or combinations thereof.
- Primary, secondary and tertiary amino groups may be neutralized with inorganic or organic acids such as sulfonic acids, formic acid, acetic acid, trifluoroacetic acid and others.
- Zwitteronic compounds comprise equivalent numbers of acidic and basic groups.
- macromolecular surfactant as used herein shall to be understood as defined e.g. by M. B. Rosen in “Surfactants and Interfacial Phenomena” (John Wiley + Sons 1978) but shall also comprise materials beyond this definition behaving merely as protective colloids.
- the materials may be used in concentrations up to about 30% by weight of the ink formulation and act at the surface and interface of the numerous components of the ink which are present as solids or liquids.
- the macromolecular surfactants which are used according to the invention have a .[.number.]. .Iadd.weight .Iaddend.average molecular weight in the range from 1000 to 150,000, preferably of from 3000 to 20,000. They may be selected from the hereafter listed classes of surfactants and their mixtures. In particular, the following groups of surfactants are preferred:
- Macromolecular surfactants of group A-F with monomolecular surfactants of nonionic, anionic or cationic nature are provided.
- the correct selection of the particular macromolecular surfactant composition will depend upon the particular ink composition and may easily be determined by the one skilled in the art by few and simple tests.
- macromolecular surfactants which may be used in the inks of this invention are:
- Alkyd resins and modified alkyd resins phenolic, epoxy, urethane, silicone, acrylic or vinylic modified alkyd resins.
- the acid number is comprised between 10 and 150 mg KOH/g resin.
- Epoxy resins and modified epoxy resins carrying carboxylic acid groups carrying carboxylic acid groups.
- the acid number is comprised between 30 and 200 mg KOH/g resin.
- Block copolymers containing polyether or polyamine sections 1.
- Copolymers based on vinylacetate and other vinylmonomers of different molecular weight and degree of hydrolysis 1.
- relatively high amounts of a water can be incorporated into the ink in replacement of a portion of the normally used amount of volatile organic solvents, in such proportions that the ink contains up to 30% of water, referred to the total weight of the ink. (All percentages given below refer to that total weight of the printing ink if not otherwise indicated.) It is believed that the macromolecular surfactants act as solubilizers or compatibility enhancers for the water to be incorporated. At the same time, and this has already been described, the amount of organic solvent which is typically from 20 to 30%, could be lowered under the mark of 15% and even below 12% and 10% by weight.
- the concentration of the aqueous sodium hydroxyde solution used to clean the plastisol or rubber covered wiping cylinder which wipes off the excess ink from the non-image areas of the engraved steel die before printing can drastically be reduced.
- concentration of the aqueous sodium hydroxyde solution used to clean the plastisol or rubber covered wiping cylinder which wipes off the excess ink from the non-image areas of the engraved steel die before printing can drastically be reduced.
- an aqueous NaOH solution of 0.3 to 1% NaOH is typically used, this amount may be reduced to about 0.1% by weight or the solution may even be replaced by deionized water.
- This advantage of the invention reduces the consumption of hazardous and expensive substances and renders the solution less aggressive.
- an ink of the invention contains up to 20% by weight of a solvent phase, 1% to about 8% by weight thereof being water with organic solvents as the remainder, the total amount of organic solvent being not more than 15%, preferably 12% by weight of the ink.
- another ink of the invention contains up to 30% by weight of a solvent phase, about 8% to about 20% by weight thereof being water, with organic solvents as the remainder, the total amount of organic solvent being not more than 12%, preferably less than 10% by weight of the ink.
- an ink of the invention contains up to 35% of a solvent phase, about 8% to about 30% by weight thereof being water, with organic solvents as the remainder, the total amount of organic solvent being not more than 15%, preferably 12%, most preferably 5% by weight of the ink.
- the inks of this invention are generally prepared as follows. All parts are by weight:
- 10 to 80 parts, preferably 10 to 40 parts, more specifically 15 parts of oleoresinous ink binder (I) are mixed with 10 to 60 parts, preferably 20 parts of a film forming macromolecular surfactant selected from the aforenamed classes A to G to form an ink base (II) which will be used for grinding of pigments and extenders.
- this base (II) 20 to 50 parts of this base (II) are premixed with 50 to 80 parts of pigments and/or extenders on a butterfly mixer as e.g. manufactured by Buhler in Switzerland or Molteni in Italy.
- This premixed paste is then transferred to grinding equipment .[.sudh.]. .Iadd.such .Iaddend.as three roll-mills e.g. 1300 SDVE as manufactured by Buhler of Switzerland or any other grinding equipment such as continuously working ball or bead mills such as cobal mill MS50 manufactured by Frvma in Rheinfelden, Switzerland.
- the grinding process is stopped as soon as a fineness of less than 10 microns is obtained.
- the pigment paste is then transferred to a heavy duty mixer as e.g. a Vollrath VDDX 80, manufactured by Vollrath in West-Germany for the optional introduction of deionized water and other ink additives such as wax compounds, drying catalysts, .[.to.]. antioxidants and other ingredients known to be useful in printing ink formulations.
- the manufacturing process finishes with a 30 to 40 minutes mixing operation under vacuum of 0.01 to 0.1 bar in order to take out any dispersed air.
- the paste ink is presented to the laboratory of quality assurance for final check of colour characteristics, rheology and printing performance.
- the necessary equipment is the same as for conventional printing inks and does not need to be described here.
- the viscosity of this new type of intaglio inks for the engraved steel die printing process is comprised within 1 to 15, more specifically within 3 to 8 Pa.s at 40° C. and a shear rate of 1000 sec -1 .
- the water containing intaglio inks manufactured in the now described manner are products being stable at temperatures within -30° to +50° C. for more than 1 year.
- oleoresinous compounds (I) the following types of resins can be used: medium to long oil content alkyd resins, vinyl-acrylic, siloxane, phenolic resin or urethane modified alkyd resins, addition products of phenolic resin or rosin esters to vegetable oils or polybutadien derivatives, mineral oil soluble copolymers, epoxide resins, epoxide esters of fatty esters or any other film forming conventional binder useful for printing ink formulation.
- the remaining components of the engraved steel die printing inks of the invention are substantially the same as in the inks known heretobefore, with the exception of the reduced amount of oleoresinous components and of the presence of a polar phase as part of the oleoresinous component, allowing stabilisation of water within the ink system without altering chemical and mechanical resistances of the final print.
- the level of these resistances has been strictly recommended by the fifth International Conference on currency and counterfeiting by the International criminal police Organization (INTERPOL).
- the invention now permits .[.to fit in.]. even with the most stringent .Iadd.legislation .Iaddend.to be met in that the content of volatile organic solvents of the printing ink could be decreased under the mark of 12%, even 10%, by weight.
- rosin modified phenolic resin 60 parts are first reacted with 25 parts of raw tung oil at 220° C. for two hours. The product is then dissolved in 15 parts of a mineral oil (boiling range 170°-260° C.). The acid number is situated between 75 and 90 mg KOH/g resin. The .[.number.]. .Iadd.weight .Iaddend.average molecular weight, determined by GPC analysis, is .[.2000.]. .Iadd.2156 .Iaddend.g/mol. Finally, the product is neutralized with an aqueous solution of 25% potassium hydroxyde to a pH of 8. The final acid value is below 10 mg KOH/g resin.
