Fremgangsmåte til fremstilling avMethod for the production of
plantrykkformer med laserstråler.planographic printing forms with laser beams.
I IN
Oppfinnelsen vedrører en fremgangsmåte til fremstilling av plantrykkformer, hvor en aluminiumsbærer dekket med et opptegningssjikt inneholdende en diazoforbindelse bestråles billedmessig med en laserstråle og derved frembringes i opptegningssjiktet oleofile eller uoppløselige billedsteder. The invention relates to a method for producing planographic printing forms, where an aluminum carrier covered with a recording layer containing a diazo compound is irradiated imagewise with a laser beam and thereby produces oleophilic or insoluble image locations in the recording layer.
I US-patent 3.664.737 omtales en trykkplate som har et UV-lysfølsomt sjikt, fortrinnsvis et diazosjikt på en alu-miniumbærer og som bestråles med laser. US patent 3,664,737 mentions a printing plate which has a UV light-sensitive layer, preferably a diazo layer on an aluminum carrier and which is irradiated with a laser.
I tysk patent 2.448.325 og DOS 2.543.820 omtales fremstillingen av trykkplater ved laserbestråling av ikke lys-følsomt opptegningssjikt, idet de bestrålte steder av opptegningssjiktet blir permanent oleofile, eller hvis sjiktet allerede var oleofilt blir- uoppløselige i en egnet fremkallingsvæske. Som bære-materiale nevnes bl.a. anodisert aluminium. German patent 2,448,325 and DOS 2,543,820 refer to the production of printing plates by laser irradiation of a non-light-sensitive recording layer, the irradiated areas of the recording layer becoming permanently oleophilic, or if the layer was already oleophilic, becoming insoluble in a suitable developing liquid. As a carrier material, e.g. anodised aluminium.
I en eldre tysk søknad P 27 25 308 foreslås videre med laserstråler å billeddanne en forsensibilisert trykkplate med en bærer av eventuelt anodisert aluminium og et lysfølsomt sjikt som inneholder en negativt arbeidende diazoniumforbindelse. In an older German application P 27 25 308, it is further proposed to use laser beams to image a pre-sensitized printing plate with a carrier of possibly anodized aluminum and a light-sensitive layer containing a negatively working diazonium compound.
Det er tidligere kjent en fremgangsmåte til fremstilling av plantrykkformer, hvor et opptegningsmateriale med en sjiktbærer av anodisk oksydert aluminium.og et opptegningssjikt på oksydsjiktet bestråles billedmessig med en laserstråle, og derved gjøres de bestrålte deler av opptegningssjiktet oleofilt og resp. eller uoppløselig, og deretter utvaskes eventuelt ikke-bestrålte områder av opptegningssjiktet med en fremkallervæske, idet denne fremgangsmåte erkarakterisert vedat det anvendes en sjiktbærer med et oksydsjikt som har en sjiktvekt på minst 3 g/m 2. A method for the production of planographic printing forms is previously known, where a recording material with a layer carrier of anodically oxidized aluminum and a recording layer on the oxide layer is image-wise irradiated with a laser beam, thereby making the irradiated parts of the recording layer oleophilic and resp. or insoluble, and any non-irradiated areas of the recording layer are then washed out with a developer liquid, this method being characterized by the use of a layer carrier with an oxide layer which has a layer weight of at least 3 g/m 2 .
Oppfinnelsens oppgave er å øke følsomheten av et opptegningsmateriale i henhold til ovennevnte fremgangsmåte med lysfølsomt sjikt i forhold til laserstråling, og resp. eller øke trykningsydelsen av hermed fremstilte trykkformer. The task of the invention is to increase the sensitivity of a recording material according to the above-mentioned method with a light-sensitive layer in relation to laser radiation, and resp. or increase the printing performance of printing forms produced thereby.
Oppfinnelsen vedrører en fremgangsmåte til fremstilling av plantrykkformer i henhold til ovennevnte fremgangsmåte. Fremgangsmåten ifølge oppfinnelsen erkarakterisert vedat det anvendes et opptegningssjikt som inneholder en negativt arbeidende lysherdbar diazoforbindelse og en aminharpiks. The invention relates to a method for producing planographic printing forms according to the above-mentioned method. The method according to the invention is characterized by the use of a recording layer which contains a negatively working light-curable diazo compound and an amine resin.
Negativt arbeidende lysherdbare diazoforbindelser som er egnet til anvendelse ved fremgangsmåten ifølge oppfinnelsen er spesielt polykondensasjonsprodukter av diazoniumsalter, som også betegnes som diazoharpikser. Egnede polykondensasjonsprodukter fåes ved kondensasjon av aromatiske diazoniumsalter, fortrinnsvis av eventuelt substituerte difenylamin-4-diazoniumsalter, med aktive karbonylforbindelser, fortrinnsvis formaldehyd i sterkt surt medium. Slike produkter er f.eks. omtalt i tyske patenter nr. 1.214.086 og 1.292.001. Spesielt foretrekkes blandingskondensasjonsprodukter av diazoniumsaltenheter og enheter av ikke-lysfølsomme kondenserbare tokomponenter, som aromatiske aminer, fenoler, tiofenoler, fenol-etere, aromatiske tioetere, aromatiske hydrokarboner, aromatiske heterocykler og organiske syreamider. Slike kondensasjonsprodukter er omtalt i US patenter nr. 3.849.392 og 3.867.147. Dessuten er det egnet negativt arbeidende diazoforbindelser av typen p-benzokinondiazider og p-iminokinondiazider, slik de f.eks. er omtalt i tysk patent nr. 1.104.824. Negatively working light-curable diazo compounds which are suitable for use in the method according to the invention are in particular polycondensation products of diazonium salts, which are also referred to as diazo resins. Suitable polycondensation products are obtained by condensation of aromatic diazonium salts, preferably of optionally substituted diphenylamine-4-diazonium salts, with active carbonyl compounds, preferably formaldehyde in a strongly acidic medium. Such products are e.g. mentioned in German patents No. 1,214,086 and 1,292,001. Particularly preferred are mixed condensation products of diazonium salt units and units of non-photosensitive condensable bicomponents, such as aromatic amines, phenols, thiophenols, phenol ethers, aromatic thioethers, aromatic hydrocarbons, aromatic heterocycles and organic acid amides. Such condensation products are discussed in US patents no. 3,849,392 and 3,867,147. Also suitable are negatively working diazo compounds of the type p-benzoquinone diazides and p-iminoquinone diazides, such as those e.g. is mentioned in German patent no. 1,104,824.
Som aminharpikser anvendes fortrinnsvis amin-formaldehyd-harpikser som oppstår ved kondensasjon av formaldehyd med urinstoff, uretaner (karbamidsyreestere), anilin eller melamin. Slike kondensasjonsprodukter er kjent og oppnåelige i mange ut-førelser som handelsprodukter. Egnede representanter er f.eks. omtalt i Kunststoff-Handbuch, bind X, utgitt av Vieweg und Becker i Carl Hauser Verlag, Munchen 1968. As amine resins, amine-formaldehyde resins are preferably used, which result from the condensation of formaldehyde with urea, urethanes (carbamic acid esters), aniline or melamine. Such condensation products are known and obtainable in many forms as commercial products. Suitable representatives are e.g. discussed in Kunststoff-Handbuch, volume X, published by Vieweg und Becker in Carl Hauser Verlag, Munich 1968.
For fremstilling av laserstrålefølsomme opptegningssjikt tilsettes aminharpiksen til oppløsningen som inneholder diazoforbindelsen som skal anvendes og tjener til belegning av den anodiserte aluminium. Mengden harpiks kan svinge innen vide grenser. Den ligger vanligvis mellom 0,1 og 10 vektdeler harpiks, referert til en vektdel av den anvendte diazoforbindelse. Spesielt gode resultater får man når tilsetningen av harpiks ligger mellom ca. 0,6 og 6,0 vektdeler på 1 vektdel diazoforbindelse. For the production of laser beam-sensitive recording layers, the amine resin is added to the solution containing the diazo compound to be used and serves to coat the anodized aluminium. The amount of resin can fluctuate within wide limits. It is usually between 0.1 and 10 parts by weight of resin, referred to one part by weight of the diazo compound used. Particularly good results are obtained when the addition of resin is between approx. 0.6 and 6.0 parts by weight of 1 part by weight of diazo compound.
Sjiktbærerne av de ved fremgangsmåten ifølge oppfinnelsen anvendte opptegningsmaterialer fremstilles på kjent måte. Fortrinnsvis opprues aluminiumet før den anodiske oksydasjon mekanisk, kjemisk eller elektrolytisk..Kombinasjonen av en elektrolytisk oppruing med en anodisk oksydasjon har vist seg spesielt egnet i kontinuerlig fremgangsmåte. Oppruingen foregår, The layer carriers of the recording materials used in the method according to the invention are produced in a known manner. The aluminum is preferably roughened before the anodic oxidation mechanically, chemically or electrolytically. The combination of an electrolytic roughening with an anodic oxidation has proven particularly suitable in a continuous process. The upheaval takes place,
i et bad av fortynnet vandig mineralsyre, f.eks. av salt- eller salpetersyre under anvendelse av like- eller vekselstrøm. in a bath of dilute aqueous mineral acid, e.g. of hydrochloric or nitric acid using direct or alternating current.
Anodiseringen foregår likeledes i vandige syrer, f.eks.i svovelsyre eller fosforsyre, fortrinnsvis under anvendelse av likestrøm. Strømtettheten og anodiseringstidene avstemmes derved således at det fåes oksydsjikttykkelser i de angitte områder. Sjikttykkelsen bør minst utgjøre 3 g/m . Den øvre grense av sjikttykkelsen er ikke kritisk, imidlertid oppnås vanligvis ikke noen vesentlige forbedringer over 15 g/m 2. Ved vesentlig høyere sjikt-tykkelser, omtrent over 30 g/m 2, består i tillegg den fare at det ved bøynint kan danne seg riss i oksydsjiktet. Oksydsjiktvekter på ca. 5 til 12 g/m 2foretrekkes vanligvis. The anodization also takes place in aqueous acids, e.g. in sulfuric acid or phosphoric acid, preferably using direct current. The current density and the anodization times are thereby adjusted so that oxide layer thicknesses are obtained in the indicated areas. The layer thickness should be at least 3 g/m. The upper limit of the layer thickness is not critical, however, usually no significant improvements are achieved above 15 g/m 2. At significantly higher layer thicknesses, approximately above 30 g/m 2, there is also the danger that it may form during bending cracks in the oxide layer. Oxide layer weights of approx. 5 to 12 g/m 2 is usually preferred.
De UV-lysfølsomme diazosjikt ifølge oppfinnelsen fremkalles etter laserbestråling med vandige alkaliske eller sure oppløsninger eller også med vann. Egnet er også lakkemulsjoner eller lakker, slik de er kjent for plantrykkplater. Disse lakk-emuls joner og lakker.kan anvendes i en arbeidsprosess til fremkalling og lakkering eller også etter fremkalling med vandige opp-løsninger. The UV light-sensitive diazo layers according to the invention are developed after laser irradiation with aqueous alkaline or acidic solutions or also with water. Lacquer emulsions or varnishes, as they are known for planographic printing plates, are also suitable. These varnish emulsions and varnishes can be used in a working process for development and varnishing or also after development with aqueous solutions.
Egnet for formålet ifølge oppfinnelsen er ydelses-rette, kortbølgede lasere, eksempelvis Argon-lasere og Krypton-lasere som alt etter typen av det anvendte speil emitterer i UV-området med stråleydelser fra 0,5 til ca. 2,5 watt eller i synlige områder med strålingsydelser fra 1 til 25 watt. De ifølge oppfinnelsen anvendte sjikt kan fortrinnsvis tilsettes farvestoffer, f.eks.rhodaminer, trifenylmetanfarvestoffer som krystallfiolett, astrazon-orange, eosin og metylenblå, som absorberes sterkt i det emitterte område og utøver en sensibiliserende virkning. Suitable for the purpose according to the invention are performance-correct, short-wave lasers, for example Argon lasers and Krypton lasers which, depending on the type of mirror used, emit in the UV range with beam powers from 0.5 to approx. 2.5 watts or in visible areas with radiation outputs from 1 to 25 watts. Dyes, e.g. rhodamines, triphenylmethane dyes such as crystal violet, astrazone orange, eosin and methylene blue, can preferably be added to the layers used according to the invention, which are strongly absorbed in the emitted area and exert a sensitizing effect.
Laserstrålen styres ved hjelp av en på forhånd gitt programmert strek- og/eller rasterbevegelse. Fremgangsmåte og innretning til regulering av laserstrålen ved hjelp av computere, samt bunting, modulering resp. avstyring av strålen omfattes ikke av oppfinnelsen; de er omtalt flere ganger, eksempelvis i det The laser beam is controlled using a pre-programmed line and/or raster movement. Method and device for regulating the laser beam using computers, as well as bundling, modulation or deflection of the beam is not covered by the invention; they are mentioned several times, for example in that

Sjiktene bestråles billedmessig fortrinnsvis medThe layers are image-wise preferably irradiated with
en argon-laser av 1 til 10 watt. Alt etter de anvendte sjikts følsomhet resp. absorbsjonsevner oppnås hastigheter inntil 110 m og mer pr. sekund. Ved fokusering av laserstrålen-med et objektiv oppstår på sjiktet herdede flekker på mindre enn 50 ym diameter. an argon laser of 1 to 10 watts. Depending on the sensitivity of the layers used or absorption capabilities, speeds of up to 110 m and more are achieved per second. When focusing the laser beam with an objective, hardened spots of less than 50 ym diameter appear on the layer.
Ved hjelp av oppfinnelsen bevirkes en meget permanent oleofilering av overflaten, således at det kan oppnås høye trykkopplag. ■ Dessuten er følsomheten av de anvendte opptegningsmaterialer for laserstråling spesielt høy. With the help of the invention, a very permanent oleophilization of the surface is effected, so that high pressure runs can be achieved. ■ In addition, the sensitivity of the recording materials used to laser radiation is particularly high.
