Description
Den foreliggende oppfinnelse angår varmef01somme kopieringsark. The present invention relates to heat-sensitive copying sheets.
Oppfinnelsen .er spesielt anvendelig i forbindelse med kopieringsark i form av gjennomsiktige filmer for fremstilling av gjennomsiktige bilder for projektorer av autotypioriginaler --v.ed termografiske kopierings-fremgangsmåter. -Den termograf iske kopieringsprosess slik den først er _±>eskrevet i UVS. patentskrift nr.. 2.7^0 ./8 96, omfatter--å utsette en original «om .står i varmeledende berøring med et varmefølsomt kopieringsark, for en kortvarig eksponering med intens stråling. Ved slike .prosesser kan det -varmemønster som dannes ved brede linder eirer ^lokkformede biiled-områder, oygge .seg opp raskere enn ved-smale -linjer eli er områder med The invention is particularly applicable in connection with copying sheets in the form of transparent films for producing transparent images for projectors of autotype originals -- by thermographic copying methods. -The thermographic copying process as it is first _±>escribed in UVS. patent document no. 2.7^0 ./8 96, includes--exposing an original "if .stands in heat-conducting contact with a heat-sensitive copying sheet, to a brief exposure to intense radiation. In such processes, the heat pattern that is formed by wide lines or lid-shaped bilead areas can build up faster than by narrow lines or areas with
fine detaljer, noe somTører.til uskar-phet i de førstnevnte områder eller bare delvis kopiering i de sistnevnte .områder når det-anvendte kopieringsark har. et utilstrekkelig eksponerings-spillerom. Kopieringsark-konstruksjoner som er basert på sølv-såper-eaksj onsbestanådeier, som beskrevet i U.S. patentskrift nr. 2.910.377, .skaffer tette, _sorte bilder, men eksponeringen må innstilles omhyggel-ig for at -der skal oppnås et anvendelig spillerom. -Økt spillerom oppnås med kopieringsark-konstruk-sjoner som er-basert på jemsåper som-beskrevet i U.S. patentskrift nr . 2.663. men selv med disse ark^er det "funnet vanskelig "å oppnå fine details, something like Dry to blur in the former areas or only partial copying in the latter areas when the used copy sheet has. an insufficient exposure leeway. Copy sheet constructions based on silver-soap reaction properties, as described in U.S. Pat. patent document no. 2,910,377, obtains dense, black images, but the exposure must be set carefully in order to achieve a usable leeway. -Increased leeway is achieved with copy sheet constructions that are based on jam soaps as described in U.S. Pat. patent document no. 2,663. but even with these sheets it has been "found difficult "to achieve
en fullstendig tilfredsstillende gjengivelse av både fine og tykke linjer eller mønstre. a completely satisfactory reproduction of both fine and thick lines or patterns.
Overraskende nok er det nå funnet at. en kombinasjon av sølv- og jernsåpe vil_gi en kopieringsarksammensetning med et sterkt overlegent eksponerings-spillerom sammenlignet med sammensetninger hvor den ene eller den annen av de nevnte såper anvendes hver for seg. Denne opp-dagelse tillater nøyaktig gjengivelse av både fine detaljer og utstrakte billedområder på ett og samme ark og har medført at det blir mulig å fremstille fremragende^detaljrike transparenter for projeksjons-apparater fra autotypioriginaler og andre originaler som er vanskelige å reprodusere. Surprisingly, it has now been found that. a combination of silver and iron soap will give a copying sheet composition with a greatly superior exposure leeway compared to compositions where one or the other of the aforementioned soaps is used separately. This discovery allows accurate reproduction of both fine details and extended image areas on one and the same sheet and has meant that it is possible to produce outstandingly detailed transparencies for projection devices from autotype originals and other originals that are difficult to reproduce.
Den foreliggende oppfinnelse går derfor ut på et varmefølsomt arkmateriale omfattende et tynt skikt som kan gi et synlig sølv- The present invention is therefore based on a heat-sensitive sheet material comprising a thin layer which can give a visible silver
bilde ved varmepåvirkning og inneholder metallsåper av langkjedede fettsyrer, en toner for sølvbildet og en fenol-ko-reaksjonsbestand- image when exposed to heat and contains metal soaps of long-chain fatty acids, a toner for the silver image and a phenol co-reaction agent
del for såpene,karakterisert vedat skiktet inneholder en blanding av jern- og sølvsåper av langkjedede fettsyrer, idet sølvsåpen ut- part for the soaps, characterized in that the layer contains a mixture of iron and silver soaps of long-chain fatty acids, as the silver soap
gjør 10 - 80% av blandingen. make 10 - 80% of the mix.
De varmefølsomme kopieringsark med sølvsåpe danner et synlig bilde, ved hjelp av en oksydasjons/reduksj ons-reaksj on. I jernsåpe-skikténe foregår der en annen reaksjon, sannsynligvis en chelatdannende reaksjon. Separate ko-reaksjonsbestanddeler kan anvendes, men det. er funnet mulig å anvende den samme ko-reaksjonsbestanddel for begge metallsåpe-reaksjonsbestanddelene,. Forbindelser som pyrogalius-syre, pyrokatekin, protokateku-syre, azelayl-pyrogallus-syre,.. azelayl-bis-pyrogallus-syre, metylgallat og behenoyl-pyrogallol er spesielt virk-somme. Det vil ses at -alle disse forbindelser er flerverdige fenoler. Blandinger av slike og andre ko-reaksjonsbestanddeler for metallsåpene kan anvendes, f.eks. for oppnåelse av bilder med foretrukne fargetoner. Det. er kjent at tonere som f.eks. ftalazinon forbedrer sølvbildet i kopieringsark basert på sølvsåper, og slike tonere er funnet å-være ønskelige i produktet ifølge den foreliggende oppfinnelse, f.eks. i en mengde på ca. 15 - 20 vektprosent av sølvsåpen. Polymere filmdannende bindemidler som ikke smelter sammen ved de temperaturer som anvendes ved kopieringen, vil "vanligvis bli innlemmet i mengder som er tilstrek-keTige til at der dannes et glatt, godt heftende skikt. Sammensetningene kan påføres på papir, eller andre ikke gjennomsiktige oærematerialer:, og_når de anvendes på denne måte, kan de inneholde pigmenter, fyll-, stoffer og andre-tilsetninger. Spesielt-ønskelige resultater oppnås ved anvendelse av klare gjennomsiktige belegg på bærematerialer _av gjennomsiktig film, idet de resulterende kopier da med glimrende resultater kan anvendes som gjennomsiktige kopier for anvendelse i lysbildefremvisere, f. eks. såkalte "o.ver-head"-proj eksjonsapparater. The heat-sensitive copying sheets with silver soap form a visible image, using an oxidation/reduction reaction. In the iron soap layers, another reaction takes place, probably a chelating reaction. Separate co-reaction components can be used, but it. it has been found possible to use the same co-reaction component for both metal soap reaction components. Compounds such as pyrogallic acid, pyrocatechin, protocatechuic acid, azelayl-pyrogallic acid,... azelayl-bis-pyrogallic acid, methyl gallate and behenoyl-pyrogallol are particularly effective. It will be seen that -all these compounds are polyhydric phenols. Mixtures of such and other co-reaction components for the metal soaps can be used, e.g. for obtaining images with preferred color tones. The. it is known that toners such as phthalazinone improves the silver image in copying sheets based on silver soaps, and such toners have been found to be desirable in the product of the present invention, e.g. in an amount of approx. 15 - 20 percent by weight of the silver soap. Polymeric film-forming binders that do not melt together at the temperatures used in the copying process will usually be incorporated in amounts sufficient to form a smooth, well-adherent layer. The compositions can be applied to paper or other non-transparent non-transparent materials: , and_when used in this way, they may contain pigments, fillers, substances and other additives. Particularly desirable results are obtained by the use of clear transparent coatings on carrier materials _of transparent film, the resulting copies then with excellent results being used as transparent copies for use in slide projectors, eg so-called "over-head" projection apparatus.
De følgende spesielle eksempler, hvor alle bestanddeler er angitt The following special examples, where all components are indicated
i vektdeler med mindre noe annet er nevnt, tjener til ytterligere belysning av oppfinnelsen. in parts by weight, unless otherwise mentioned, serves to further elucidate the invention.
Eksempel 1 Example 1
En første beleggsamménsétning fremstilles ved sammenblanding av A first coating composition is produced by mixing of
20 deler av en 20%'s dispersjon av ferristearat i etanol, 20 deler av 20 parts of a 20% dispersion of ferric stearate in ethanol, 20 parts of
en 2055 ,'s dispersjon av sølv-behenat i etanol, 0,6^6 deler ftålazinon, 66,66 deler av en 1555's oppløsning av polyvinylacetat i aceton og:- a 2055 ,'s dispersion of silver behenate in ethanol, 0.6^6 parts of phthalazinone, 66.66 parts of a 1555's solution of polyvinyl acetate in acetone and:-
88,5 deler aceton. Blandingen påføres en polyetentereftalat-polyesterfilm i en tykkelse av 0,05 'mm og en mengde av 5, 9 g/m 2etter tørking. 88.5 parts acetone. The mixture is applied to a polyethylene terephthalate polyester film with a thickness of 0.05 mm and an amount of 5.9 g/m 2 after drying.
En annen beleggsamménsétning fremstilt ved oppløsning av 2-0'deler celluioseacetatbutyrat og 4 deler metylgallat i l80 deler metyletyi-keton påfør.es over det første skikt i en mengde av 3>2 g/nr etter' tørking. De to skikt danner, et tynt, synbart varmef'ølsomt skikt. Another coating composition prepared by dissolving 2-0 parts cellulose acetate butyrate and 4 parts methyl gallate in 180 parts methyl ethyl ketone is applied over the first layer in an amount of 3-2 g/no after drying. The two layers form a thin, visibly heat-sensitive layer.
Den belagte film er klar og gjennomsiktig med en svak-brungul farge. Et parti av filmen anbringes i direkte anlegg mot en original med sorte trykkbokstaver på et bæremateriale av hvitt papir. En kort eksponering med intens stråleenergi gjennom filmen i en termografisk kopieringsmaskin fører til en reproduksjon av billedområder på filmen. Billedtettheten er ca. 1,1. Bilder med en tetthet på over ca. 0,6 er effektive når det gjelder å gi lysbilder som er lett synlige når de vises.i et opplyst værelse. The coated film is clear and transparent with a faint brownish yellow color. A part of the film is placed in direct contact with an original with black printed letters on a support material of white paper. A short exposure with intense radiant energy through the film in a thermographic copying machine leads to a reproduction of image areas on the film. The image density is approx. 1.1. Images with a density of over approx. 0.6 are effective when it comes to providing slides that are easily visible when displayed in a lighted room.
Et annet parti av filmen anvendes til fremstilling av en kopi av en trykt autotypioriginal på lignende måte. De mørke billedområder blir reprodusert som tette, sorte flater, mens bildene av de lysere områder har meget mindre tetthet og en svak purpurtone. Another part of the film is used to make a copy of a printed autotype original in a similar way. The dark image areas are reproduced as dense, black surfaces, while the images of the lighter areas have much less density and a faint purple tone.
Eksempel 2 Example 2
En sølvsåpedispersjon fremstilles ved sammenblanding av 6-0 deler sølv-behenat, 2 k0 deler etanol, 75 deler polyvinylacetat, 11,25 deler ftålazinon og LO89 deler aceton. A silver soap dispersion is prepared by mixing 6-0 parts silver behenate, 2 k0 parts ethanol, 75 parts polyvinyl acetate, 11.25 parts phthalazinone and LO89 parts acetone.
En jernsåpedispersjon fremstilles på lignende måte ved sammenblanding av €0 deler ferristearat, -240 deler etanol, 75 deler polyvinylacetat og liOO deler aceton. An iron soap dispersion is prepared in a similar manner by mixing €0 parts ferristearate, -240 parts ethanol, 75 parts polyvinyl acetate and 100 parts acetone.
De to dispersjoner blandes sammen i forskjellige forhold som angitt i den etterfølgende tabell I. Blandingene belegges på en 0,025 mm tykk polyesterfilm gjennom en belegningsåpning på 0,1 mm,, og beleggene tørkes i en ovn ved temperaturer som ikke er høyere enn ca. 93°C. Hvert prøvestykke blir deretter ytterligere belagt meden sammensetning som inneholder 9,-8 deler celluioseacetatbutyrat og 2,0 deler metylgallat i 88-,2 deler_mety!etylketon, og som påføres gjennom en 0,075 mm's åpning, hvoretter -arket igjen tørkes. På-de forskjellige prøvestykker tlldannes der på termografisk vei et bilde ved at-prøvestykkene anbringes i anlegg mot en original som er forsynt med både brede og smale trykte linjer-, og som deretter gjennom prøvestykket eksponeres for intens s.tråleenergi i avtagende tidsrom over lengden av linjene.. Prøven kan passende utføres i et termograf isk apparat,, hvor frem-føringshastigheteri for kopieringsarkét ~©g den trykte original forti én linjeformet kilde for intens stråling-økes jevnt, hvorved der fås et _graf isk bilde av eksponeringsspillerommet. Ved overdrevet lang The two dispersions are mixed together in different ratios as indicated in the following Table I. The mixtures are coated on a 0.025 mm thick polyester film through a coating opening of 0.1 mm,, and the coatings are dried in an oven at temperatures not higher than approx. 93°C. Each sample is then further coated with a composition containing 9.8 parts cellulose acetate butyrate and 2.0 parts methyl gallate in 88.2 parts methyl ethyl ketone, which is applied through a 0.075 mm opening, after which the sheet is again dried. On the various test pieces, a thermographic image is formed where the test pieces are placed in contact with an original which is provided with both wide and narrow printed lines, and which is then exposed through the test piece to intense s.ray energy for a decreasing period of time over the length of the lines.. The test can conveniently be carried out in a thermographic apparatus, where the advance speed of the copy sheet and the printed original for one line-shaped source of intense radiation is steadily increased, whereby a graphic image of the exposure space is obtained. When excessively long
-eksponering ©lir kopien uklar, idet spesielt de tykke linjer blir bredere og~oppviser ru-, bølgeformede kanter. Ved for kort eksponering blir tettheten av -kopien redusert., og de"tynneste linjer på originalen blir ikke reprodusert. Eksponeringsområdet mellom disse ekstremer, ut-gjør kopierlngsarkets spillerom. Den følgende tabell I angir tallmessig det relative spillerom for koperlngsark som -er fremstilt og utprøvd som beskrevet ovenfor, idet området mellom 100$ sølvsåpe og i00^ jernsåpe er dekket i" sprang på 10%.. -exposure leaves the copy unclear, as the thick lines in particular become wider and exhibit rough, wavy edges. If the exposure is too short, the density of the copy is reduced, and the thinnest lines on the original are not reproduced. The exposure area between these extremes constitutes the copy sheet's leeway. The following table I numerically indicates the relative leeway for copy sheets that have been produced and tested as described above, the area between 100$ silver soap and i00^ iron soap being covered in" leaps of 10%..
Overraskende nok jzikes spillerommet _for blandinger som inneholder 10-80$ sølvsåpe-, til en verdi som langt overstiger den som oppnås med den-ene eller den annen av såpene alene. Surprisingly, the leeway _for mixtures containing $10-$80 of silver soap- is reduced to a value far in excess of that obtained with one or the other of the soaps alone.

En polyesterfilm som er belagt med én blanding av sølv- og jernsåper som i eksempel 3 (6,45 g/m 2), bortsett fra at der i bélegg-sammensetningen er innlemmet 2 deler tetraklor-ftalanhydrid per 100 deler metallsåpe, blir videre belagt med en oppløsning av 20 deler metylgallat, 20 deler fenoyl-pyrogallol og 200 deler celluioseacetatbutyrat i 1-8000 deler metyletylketon, idet dette belegg påføres i en mengde av 3,76 g/m 2 etter tørking. Arket anvendes ved fremstilling av A polyester film which is coated with one mixture of silver and iron soaps as in example 3 (6.45 g/m 2 ), except that 2 parts of tetrachlorophthalic anhydride per 100 parts of metal soap are incorporated in the coating composition, is further coated with a solution of 20 parts methyl gallate, 20 parts phenol pyrogallol and 200 parts cellulose acetate butyrate in 1-8000 parts methyl ethyl ketone, this coating being applied in an amount of 3.76 g/m 2 after drying. The sheet is used in the production of
