Description
Foreliggénde oppfinnelse vedrører trykkfarver, spesielt for dyptrykk. The present invention relates to printing inks, especially for gravure printing.
Kjente trykkfarver for dyptrykk inneholder vanligvis en ferniss og ett eller flere pigmenter. Bindemidlet fremstilles vanligvis av linolje eller alkydharpiks eller en fast harpiks såsom en oljeoppløselig fenol- eller1 maleinsyreharpiks, opp-løst i et oppløsningsmiddel med høyt kokepunkt, såsom et petroleumdestillat med kokepunkt i området 230 310°C, eller kombinasjoner av disse sammen med tørremidler eller sikkativer såsom coboltoctoat, i meget små mengder. De farvede pigmenter er vanligvis kombinert med inerte ekstendere, såsom kalsiumcarbonat, bariumsulfat eller andre lignende materialer som er velkjent innen trykkerifaget. Den således sammensatte trykkfarve er ved romtemperatur vanligvis stiv og har generelt en myk kittlignehdé konsistens. Når trykkfarven påføres papiret under trykkeprosessen, vil noe trekke inn i papiret og oxyderes, hvilket forårsaker at trykkfarven størkner eller herdner. Imidlertid vil den ikke størkne raskt nok etter trykkeprosessen, og hvis de trykkede ark stables på hverandre, kan trykkbildet smitte av til undersiden av tilstøtende ark. For å unngå dette problem blir trykkede ark ofte stablet med mellomliggende papirer som skal absorbere den trykkfarve som ellers ville avsettes på baksiden av til-støtende trykkede ark. Alternativt kan det trykkede papir lagres på en rull av paraffinvokset papir og vikles inn i rullen under trykkeprosessen. Known printing inks for intaglio printing usually contain a varnish and one or more pigments. The binder is usually prepared from linseed oil or alkyd resin or a solid resin such as an oil-soluble phenolic or maleic acid resin, dissolved in a high-boiling solvent, such as a petroleum distillate with a boiling point in the range of 230-310°C, or combinations of these together with drying agents or siccatives such as cobalt octoate, in very small amounts. The colored pigments are usually combined with inert extenders such as calcium carbonate, barium sulfate or other similar materials well known in the printing art. The printing ink thus composed is usually stiff at room temperature and generally has a soft putty-like consistency. When the ink is applied to the paper during the printing process, something will soak into the paper and oxidize, causing the ink to solidify or harden. However, it will not solidify quickly enough after the printing process, and if the printed sheets are stacked on top of each other, the printed image may bleed to the underside of adjacent sheets. In order to avoid this problem, printed sheets are often stacked with intermediate papers to absorb the ink that would otherwise be deposited on the back of adjacent printed sheets. Alternatively, the printed paper can be stored on a roll of paraffin waxed paper and wound into the roll during the printing process.
Ved foreliggende oppfinnelse tilveiebringes en trykkfarve som er fast ved romtemperatur, men som smelter ved oppvarmning, omfattende The present invention provides a printing ink which is solid at room temperature, but which melts when heated, comprising
a) 13 - 34 vekt% voks a) 13 - 34% by weight wax
b) eventuelt en med vokset forlikelig harpiks c) 6-19 vekt% av en ytterligere voksforlikelig komponent som herder i luften og er valgt fra gruppen av tørrende b) optionally one with a wax-compatible resin c) 6-19% by weight of a further wax-compatible component which hardens in the air and is selected from the group of drying
oljer og alkydharpikser og blandinger av disse, og oils and alkyd resins and mixtures thereof, and
d) resten - til 100 vekt% - av pigmenter, drøyemidler og ytterligere bestanddeler, hvilken trykkfarve er kjenne-tegnet ved at harpiksen h) er en hydrocarbohharpiks som - når den er tilstedeværende - finnes i en vektandel på mindre enn det dobbelte av vokset, og at trykkfarven dessuten inneholder et tørremiddel, hvorved den kan anvendes for dyptrykk av verdipapirer, idet den efter størkning blir permanent usmeltelig ved oxydasjon av den oxyderbare komponent c) under innvirkning av tørremidlet. d) the rest - up to 100% by weight - of pigments, retarding agents and additional components, which printing ink is characterized by the fact that the resin h) is a hydrocarbon resin which - when present - is found in a proportion by weight of less than twice that of the wax, and that the printing ink also contains a drying agent, whereby it can be used for intaglio printing of securities, as it becomes permanently infusible after solidification by oxidation of the oxidizable component c) under the influence of the drying agent.
Vanligvis vil det anvendes 50 - 82 vekt% av pigmentet og ekstenderen og 18 - 50 vekt% av det oxyderbare bindemiddel. Alternativt kan det anvendes 60 - 82 vekt% av pigmentet og ekstenderen og 18 - 40 vekt% av det oxyderbare bindemiddel. Usually 50 - 82% by weight of the pigment and extender and 18 - 50% by weight of the oxidizable binder will be used. Alternatively, 60 - 82% by weight of the pigment and extender and 18 - 40% by weight of the oxidizable binder can be used.
Hensikten med den foreliggende oppfinnelse er å tilveiebringe en trykkfarve som vil størkne eller herdne nesten øyeblikkelig, etter at den er påført papiret under dyptrykk-prosessen. Derved vil det oppstå minimal avsetning, om i det hele tatt noen, av trykket på baksiden av det etterfølgende ark eller tilstøtende papiroverflater hvis papiret oppvikles på en rull etter trykking ved rotasjonstrykking. Trykkfarven må bli permanent usmeltbar for at den ikke skal smelte når lufttemperaturen stiger, spesielt hvis det fremstilles sikker-hetspapirer såsom pengesedler, reisesjekker etc. Når trykkfarven én gang har størknet, må derfor den oxyderbare komponent av bindemidlet forårsake en permanent herdning. Hvis den oxyderbare komponent velges omhyggelig, og konvensjonelle sikkativer innarbeides, vil oxydasjonen finne sted i løpet av ca. 8 timer, hvilket forårsaker at trykkfarven blir permanent usmeltbar. Vokskomponenten i trykkfarven forårsaker at trykkfarven størkner meget raskt. The purpose of the present invention is to provide a printing ink which will solidify or harden almost instantly, after it has been applied to the paper during the gravure printing process. Thereby, there will be minimal, if any, deposition of the print on the back of the subsequent sheet or adjacent paper surfaces if the paper is wound onto a roll after printing by rotary printing. The printing ink must become permanently infusible so that it does not melt when the air temperature rises, especially if security papers such as banknotes, traveller's checks etc. are being produced. Once the printing ink has solidified, the oxidizable component of the binder must therefore cause a permanent hardening. If the oxidizable component is chosen carefully, and conventional siccatives are incorporated, the oxidation will take place within approx. 8 hours, causing the printing ink to become permanently infusible. The wax component in the printing ink causes the printing ink to harden very quickly.
De fleste vokser kan innarbeides i trykkfarven ifølge foreliggende oppfinnelse, og disse kan være paraffinvoks, bivoks, spermacetvoks, carnaubavoks såvel som estere av høyere fettsyrer og flerverdige alkoholer såsom glycerol. Polymere vokser såsom polyethylenvoks, er også egnet. Andre vokser som kan anvendes, er eksempelvis amider av fettsyrer. Generelt oxyderes ikke vokser til harde materialer, men amider av umettede fettsyrer kan herdne i luften. Det vil forståes at den valgte vokstype må tilfredsstille de nedenfor angitte Most waxes can be incorporated into the printing ink according to the present invention, and these can be paraffin wax, beeswax, spermacet wax, carnauba wax as well as esters of higher fatty acids and polyhydric alcohols such as glycerol. Polymeric waxes such as polyethylene wax are also suitable. Other waxes that can be used are, for example, amides of fatty acids. In general, waxes do not oxidize to hard materials, but amides of unsaturated fatty acids can harden in the air. It will be understood that the chosen type of wax must satisfy those stated below
betingelser. conditions.
Umettede oljer som kan anvendes i trykkfarven ifølge foreliggende oppfinnelse,, kan være vegetabilske oljer såsom linolje, treolje (kinesisk), dehydratisert ricinusolje eller perillaolje, men valget av olje er ikke kritisk så lenge . bindemidlet tilfredsstille r de detaljerte betingelser som angitt nedenfor. Disse tørrende oljer er ofte varmebehandlet og har en moderat viskositet. Også alkydharpikser kan inklu-deres i lakken for å tilveiebringe oxyderbarhet. Unsaturated oils that can be used in the printing ink according to the present invention can be vegetable oils such as linseed oil, wood oil (Chinese), dehydrated castor oil or perilla oil, but the choice of oil is not critical as long. the binder satisfies the detailed conditions set out below. These drying oils are often heat treated and have a moderate viscosity. Alkyd resins can also be included in the varnish to provide oxidizability.
En del av vokskomponenten kan erstattes med en fast, smeltbar hydrocarbonharpiks.som er forlikelig med vokset, i den hensikt å kontrollere viskositeten. Med "hydrocarbonhar-piks" menes her harpikser slik disse er omtalt i Kirk-Othmer: "Encyclopedia of Chemical Technology",, Second Edition, 1966, vol. 11, sider 242 - 262. A portion of the wax component can be replaced with a solid, fusible hydrocarbon resin, which is compatible with the wax, in order to control the viscosity. By "hydrocarbon resins" is meant here resins as these are discussed in Kirk-Othmer: "Encyclopedia of Chemical Technology", Second Edition, 1966, vol. 11, pages 242 - 262.
Vokstypen må velges omhyggelig, idet der tas hensyn til trykketemperaturen. Det valgte voks er fortrinnsvis et som ikke. inneholder anti-oxydant. Under dyptrykkprosesser vil trykkemaskinen generelt arbeide ved meget høye .hastigheter, og der er et visst samspill mellom valsene på pressene. Dette betyr, at der utvikles varme ved trykkprosessen muligens opp til 50°C. Det er derfor nødvendig å formulere trykkfarven slik at den har konvensjonelle egenskaper ved driftstemperaturen for pressene. Viskositeten av det oxyderbare bindemiddel som inngår i.disse trykkfarver, bør derfor være innen' området for det som er vanlig for "lakk" for konvensjonelle platetrykkfarver, dvs. 0,5 - 15 poise,. målt ved tryknings-temperaturen. Smeltede vokser har vanligvis lav viskositet, og en viss tilsetning av harpikser til vokset er ønskelig for å øke viskositeten. Trykkfarven påføres trykkepressens valser vanligvis i smeltet tilstand, og konvensjonell dyp-trykkstrykking finner sted. Selv om trykkfarven .er smeltet, må den utvise normale trykkfarveegenskaper, dvs, viskositet og "lengde", ved driftstemperaturen. Straks trykkfarven når papiret, størkner den. Papiret har romtemperatur, hvilket forårsaker at vokset i trykkfarven størkner på papiret straks dette forlater pressen. Ved formulering av trykkfarven fore- trekkes det å anvende blandinger av vokser for å oppnå deønskede optimale egenskaper. The type of wax must be chosen carefully, taking into account the printing temperature. The chosen wax is preferably one that does not. contains anti-oxidant. During gravure printing processes, the printing machine will generally work at very high speeds, and there is a certain interaction between the rollers on the presses. This means that heat develops during the printing process, possibly up to 50°C. It is therefore necessary to formulate the printing ink so that it has conventional properties at the operating temperature of the presses. The viscosity of the oxidizable binder included in these printing inks should therefore be within the range of what is usual for "varnish" for conventional plate printing inks, i.e. 0.5 - 15 poise. measured at the printing temperature. Melted waxes usually have a low viscosity, and some addition of resins to the wax is desirable to increase the viscosity. The printing ink is applied to the rollers of the printing press usually in a molten state, and conventional gravure printing takes place. Although the ink is molten, it must exhibit normal ink properties, ie, viscosity and "length", at the operating temperature. As soon as the printing ink reaches the paper, it solidifies. The paper is at room temperature, which causes the wax in the printing ink to solidify on the paper as soon as it leaves the press. When formulating the printing ink, it is preferred to use mixtures of waxes to achieve the desired optimal properties.
Den gjenværende del av trykkfarven utgjøres av de samme komponenter som for konvensjonelle dyptrykksfarver. Sikkativer er vanligvis innbefattet, og disse kan være kobber-nafthenat, manganoctoat eller blyoctoat, i mengder på 0 - 2,5, vanligvis ca. 0,5 vekt%. Pigmentene som anvendes, er konvensjonelle sådanne, og ekstenderne er fortrinnsvis kalsiumcarbonat, bariumsulfat,.magnesiumcarbonat og zinkoxyd. The remaining part of the printing ink is made up of the same components as for conventional gravure printing inks. Siccatives are usually included, and these may be copper naphthenate, manganese octoate or lead octoate, in amounts of 0 - 2.5, usually approx. 0.5% by weight. The pigments used are conventional, and the extenders are preferably calcium carbonate, barium sulphate, magnesium carbonate and zinc oxide.
Pigmentene utgjør generelt opptil 30% av den totale mengde av pigment og ekstender.. De farvede pigmenter til-fører generelt ikke tilstrekkelig konsistens, så det er nød-vendig å fortykke trykkfarven ved hjelp av en ekstender slik at trykkfarven får den korrekte viskositet. The pigments generally make up to 30% of the total amount of pigment and extender. The colored pigments generally do not add sufficient consistency, so it is necessary to thicken the printing ink with the help of an extender so that the printing ink has the correct viscosity.
Ved fremstillingen av trykkfarve vil vokskomponenten i bindemidlet vanligvis settes til en forblanding av den oxyderbare komponent, dvs. harpiksen eller oljen, og pigmentet. Ekstenderen tilsettes deretter, og hele satsen blandes med sikkativet og males deretter sammen. Det må naturligvis forståes at når farven er fremstilt, må den ikke komme i kontakt med luft. Hvis den oxyderes, vil den bli ubrukelig. In the production of printing ink, the wax component in the binder will usually be added to a premix of the oxidizable component, i.e. the resin or oil, and the pigment. The extender is then added, and the entire batch is mixed with the siccative and then ground together. It must of course be understood that when the color is produced, it must not come into contact with air. If it oxidizes, it will become useless.
Foreliggende oppfinnelse skal ytterligere beskrives under henvisning til de etterfølgende eksempler, hvori alle deler er angitt som vektdeler hvis intet annet er angitt, The present invention shall be further described with reference to the following examples, in which all parts are stated as parts by weight if nothing else is stated,
og hvor bestanddelene med samme betegnelse i de forskjellige eksempler er de samme. and where the components with the same designation in the different examples are the same.
Eksempel 1 Example 1
De to pigmenter ble malt inn i alkydharpiksen til en stiv pasta som utgjorde forblandingen, alkydharpiksen anvendt^i dette eksempel markedsføres under handelsnavnet "Surkyd 1092". Det rubinrøde pigment markedsføres under han delsnavnet "Rubine Toner 8972". The two pigments were ground into the alkyd resin to a stiff paste which constituted the premix, the alkyd resin used in this example being marketed under the trade name "Surkyd 1092". The ruby red pigment is marketed under the part name "Rubine Toner 8972".
Paraffinvoksen og hydrocarbonharpiksen, som markeds-føres under handelsnavnet "A 100", ble blandet sammen i smeltet tilstand i en blander med en oppvarmet beholder, The paraffin wax and the hydrocarbon resin, marketed under the trade name "A 100", were mixed together in a molten state in a mixer with a heated container,
og til denne blanding i varm tilstand ble tilsatt først 10 vektdeler av forblandingen og deretter 30 vektdeler kritt og 0,05 vektdeler coboltoctoat (6% cobolt). Alle bestanddelene ble malt sammen i en oppvarmet trevalsemølle, hvilket ga en trykkfarve med et smeltepunkt på ca. 53°C. and to this mixture in a hot state were added first 10 parts by weight of the premix and then 30 parts by weight of chalk and 0.05 parts by weight of cobaltoctoate (6% cobalt). All the ingredients were ground together in a heated wooden roller mill, which produced a printing ink with a melting point of approx. 53°C.
Hydrocarbonharpiksen, "A 100", er angitt å være et aromatisk hydrpcarbon, 100% ikke-flyktig uten løsningsmiddel. Smeltepunkt 95 - 105°C (Ring og Ball), løselig i tørrende oljer og uløselig i alkoholer, se "Surface Resin Index" 1974, side 20 (publisert av The British Resin Manufacturers Association). The hydrocarbon resin, "A 100", is stated to be an aromatic hydrocarbon, 100% non-volatile with no solvent. Melting point 95 - 105°C (Ring and Ball), soluble in drying oils and insoluble in alcohols, see "Surface Resin Index" 1974, page 20 (published by The British Resin Manufacturers Association).
Eksempel 2 Example 2
De følgende komponenter tole sammenblandet til en trykkfarve med.et smeltepunkt på ca. 73°C. The following components are mixed together to form a printing ink with a melting point of approx. 73°C.
Alkydharpiksen selges under handelsnavnet "Esterkyd A2". Alle bestanddeler ble blandet sammen i en oppvarmet beholder og valset i en varm trevalsers farvemølle. The alkyd resin is sold under the trade name "Esterkyd A2". All ingredients were mixed together in a heated container and rolled in a hot three-roll dye mill.
Eksempel 3 Example 3
Den anvendte alkydharpiks var den samme som anvendt i eksempel 1. The alkyd resin used was the same as used in example 1.
De to pigmenter ble malt inn i alkydharpiksen til en stiv pasta som utgjorde forblandingen. En trykkfarve ble deretter fremstilt på samme måte som angitt i eksempel 1 ved å blande de følgende bestanddeler med 6,8 vektdeler av forblandingen: The two pigments were ground into the alkyd resin to a stiff paste which made up the premix. A printing ink was then prepared in the same manner as indicated in Example 1 by mixing the following ingredients with 6.8 parts by weight of the premix:
Bestanddelene ble blandet sammen i en oppvarmet beholder og deretter malt i en varm mølle. The ingredients were mixed together in a heated container and then ground in a hot mill.
Denne trykkfarve hadde et smeltepunkt på,ca.,56°C. Det vil sees at trykkfarven ifølge dette eksempel inneholder en blanding av vokser istedenfor et enkelt voks slik som i eksempel 1 og 2. I hvert av eksemplene 1-3 anvendes en harpiks som den oxyderbare komponent. Imidlertid kan det istedet anvendes en olje eller en olje/harpiksblanding, og eksempler på slike trykkfarver er som følger: This printing ink had a melting point of approx. 56°C. It will be seen that the printing ink according to this example contains a mixture of waxes instead of a single wax as in examples 1 and 2. In each of examples 1-3 a resin is used as the oxidizable component. However, an oil or an oil/resin mixture can be used instead, and examples of such printing inks are as follows:
Eksempel 4 Example 4
Det anvendte voks selges under handelsnavnet "V-wax", og sikkativet markedsføres under handelsnavnet "Cobalt 254". The wax used is sold under the trade name "V-wax", and the siccative is marketed under the trade name "Cobalt 254".
Denne trykkfarve ble fremstilt ved den samme metode som angitt i eksempel 2 og hadde et smeltepunkt på ca. 4 7°C. This printing ink was produced by the same method as stated in example 2 and had a melting point of approx. 47°C.
Eksempel 5 Example 5
Alkydharpiksen selges under handelsnavnet "Terlon 7", oleamidet var et umettet amid av oljesyre, det blå pigment selges under handelsnavnet "Irgalite Blue BCA", og det gule krompigment selges under handelsnummeret "26437". The alkyd resin is sold under the trade name "Terlon 7", the oleamide was an unsaturated amide of oleic acid, the blue pigment is sold under the trade name "Irgalite Blue BCA", and the yellow chrome pigment is sold under the trade number "26437".
Denne trykkfarve tole fremstilt på samme måte som angitt i eksempel 2 og hadde et smeltepunkt på ca. 62°C. This printing ink was prepared in the same way as stated in example 2 and had a melting point of approx. 62°C.
I hvert av eksemplene 1-5 har vekten av pigmentet og ekstenderen oversteget vekten av det oxyderbare bindemiddel. Selv om dette generelt er foretrukket, kan imidlertid vekten av det oxyderbare bindemiddel økes, og det angis nå to eksempler hvori vekten av oxydertoart bindemiddel overstiger vekten av pigment + ekstender. In each of Examples 1-5, the weight of the pigment and extender exceeded the weight of the oxidizable binder. Although this is generally preferred, the weight of the oxidisable binder can be increased, and two examples are now given in which the weight of oxidizable binder exceeds the weight of pigment + extender.
Eksempel 6 Example 6
Alkydharpiksen var den samme som anvendt i eksempel 1. The alkyd resin was the same as used in Example 1.
Denne trykkfarve ble fremstilt på samme måte som angitt i eksempel 2 og hadde et smeltepunkt på ca. 59°C. This printing ink was produced in the same way as stated in example 2 and had a melting point of approx. 59°C.
Eksempel 7 Example 7
Alkydharpiksen er den samme som anvendt i eksempel 1. Siliciumdioxydet var erholdt ved hydrolyse av silicium-tetraklorid. The alkyd resin is the same as used in example 1. The silicon dioxide was obtained by hydrolysis of silicon tetrachloride.
Denne trykkfarve ble fremstilt på samme måte som be-skrevet i eksempel 2 og hadde et smeltepunkt på 57°C. This printing ink was produced in the same way as described in example 2 and had a melting point of 57°C.
