Opfindelsen angår strålefølsomme plader til fremstilling af litografiske trykplader.
Man kender strålingsfølsomme plader, der omfatter et strålingsfølsomt middel, der er overtrukket på et substrat.
5 Sådanne strålingsfølsomme plader anvendes til produktion af litografiske plader. Det er også kendt at overtrække strålingsfølsomme midler på et substrat, når man anvender midlerne som fotoresists.
Ued anvendelsen af strålingsfølsomme plader til fremstil-10 ling af litografiske trykplader exponeres midlet bil- ledmæssigt for actinisk stråling, således at visse dele af midlet rammes af stråling og visse dele ikke rammes.
Midlet er af en sådan art, at.de af stråling ramte dele og de ikke af stråling ramte dele udviser forskellige op-15 løseligheder i en fremkaldervæske. Den på billedmæssig måde exponerede plade fremkaldes derpå under anvendelse af væsken, således at man selektivt fjerner de mere opløselige dele og efterlader et billede, der består af de mindre opløselige dele. Billedet udgør det vandfrastøden-20 de, sværteoptagende trykkeareal af den litografiske trykkeplade, og det vandoptagende, sværtefrastødende ikke-trykkende areal af den litografiske trykplade består af overfladen af substratet, der afsløres under fremkaldelsestrinnet.
25 Man har anvendt mange forskellige strålingsfølsomme midler til at frembringe strålingsfølsomme plader. Det er kendt, at man som det strålingsfølsomme middel kan anvende en polymeriserbar forbindelse, der indeholder ethyle-nisk umættethed. I dette tilfælde polymeriserer midlet 30 ved at blive udsat for bestråling i de dele, der er ramt af strålingen, og det bliver mindre opløseligt i opløsningsmidler for de dele af overtrækket, der ikke er ramt af bestråling. Den strålingsfølsomme plade er således negativt arbejdende.

2 X EP patentskrift nr. 0005379 er der beskrevet foto-polymeriserbare midler, der omfatter en komponent, der er x stand til at polymerisere efter initiering, og en initiator for komponenten som aktiveres ved stråling.
5 Komponenten kan være en forbindelse, der indeholder ethylenisk umættethed og benyttelsen af mange forskellige typer initiatorer er beskrevet. Peroxider er beskrevet som værende sådan en type initiator og to perestere er eksemplificeret som egnede peroxider.
10
Midlerne omfatter yderligere en farvedanner og en aktivator, der omfatter en protondonor og et carbo-nylhalogenid til at konvertere farvedanneren til et mørktfarvet produkt. Midlerne benyttes i form af tørre fotoresistfilm til fremstillingen af trykte 15 kredsløb ved exponering for ultraviolet stråling. Der er intet forslag til, at peresteren kan være en keto-gruppe, der indeholder en perester, eller at midlet kan omfatte et optisk sensibiliseringsmiddel.

Passende præcursorer kan fremstilles ved at omsætte carb-oxy-aryl-ketoner med arylaldehyder under anvendelse af de metoder, der er beskrevet i US patentskrift nr. 4 162 162. Carboxy-arylketonerne kan fremstilles under anvendelse af 15 de metoder, der er beskrevet af Allinger og Jones (Journal of Organic Chemistry 70,jF7, 1962).
Forbindelser 25-50
Disse forbindelser kan fremstilles under anvendelse af metoder, som er illustreret ved følgende typiske eksempler: 20 A) Fremstilling af forbindelsen med formel 25

en opløsning af triethylamin (2,33 g) i toluen (15 ml), dråbevis over en halv time ved 10-15 °C. Reaktionsblandingen blev omrørt i 2 timer ved stuetemperatur og blev derpå filtreret. Filtraterne blev extraheret med fortyn-5 det saltsyre (ca. 1 M), vasket med vand og tørret over vandfrit magnesiumsulfat. Fast produkt blev isoleret efter fjernelse af overskydende solvent fra de tørrede ex-trakter på en roterende evaporator.

B. Fremstilling af forbindelsen med formel 27 4-t-butylperoxycarbonylbenzoyl-chlorid (BPCBC) blev fremstillet som beskrevet i det første afsnit af (A). Produktet blev isoleret som en farveløs olie, der langsomt 15 størknede, når den blev opbevaret i køleskabet efter at solvent var blevet afdampet fra filtratet af reaktionsblandingen.
En blanding af 1,2-dimethylbenzo-selenazolium-p-tosylat (1,78 g), BPCBC (2,75 g) og tørt pyridin (10 ml) blev op-20 varmet på et vanddampbad i 2 timer. Den resulterende blanding blev fortyndet til et volumen af 100 ml med toluen og holdt under omrøring, og opløsningen blev separeret fra en tjæreagtig remanens, der havde dannet sig.
Toluenopløsningen blev vasket med vand og derpå tørret 25 over magnesiumsulfat.

C) Fremstilling af forbindelsen med formel 40
Til en under omrøring stående opløsning af 1,3,3-trime-thyl-2-methylenindolin (3,6 ml) i tørt toluen (20 ml) tilsattes dråbevis en opløsning af BPCBC (6,1 g) i tørt 5 toluen (15 ml). Når tilsætningen var afsluttet, blev blandingen opvarmet til 60 °C og holdt på denne temperatur i 1,5 timer før filtrering. Efter afkøling til stuetemperatur blev toluenopløsningen extraheret med base og vasket med vand før tørring over magnesium-sulfat. Et 10 rødt, fast stof fremkom ud fra toluenopløsningen efter fjernelse af solvent på en roterende evaporator. Ved re-krystallisation af dette materiale i chloroform/methanol fremkom et produkt med smeltepunkt 76 °C (dekomp.).
Forbindelser med formlerne 51-90 15 Passende carboxylsyre-præcursorer kan fremstilles ved base-katalyseret kondensation af arylaldehyder med cyclo-alkanoner eller aryl-ketoner som illustreret ved følgende præparationer.

10 Forbindelser med formlerne 91-96
Disse forbindelser kan fremstilles ud fra tripheny1-phos-phonium-saltet af 4-(4'-brommethyl-benzoyl)-methylbenzoat, som kan fremstilles ved hjælp af den metode, der er beskrevet af Gupta et al (Journal Polymer Science 855 lj? 1981).
15 Metoderne til konvertering af phosphoniumsaltet til det sluttelige produkt er illustreret i de følgende eksempler.
Fremstilling af forbindelsen med formel 92 i) fremstilling af 4-(41-benzylidenbenzoyl)-methylbenzoat
Til en isafkølet opløsning af triphenylphosphoniumsalt af 20 4-(4'-brommethylbenzoyl)-methylbenzoat (17,85 g) i metha nol (100 ml) tilsattes dråbevis en opløsning af natrium-methoxid (1,62 g) i methanol (40 ml), efterfulgt af benz-aldehyd (3,3 g). Der dannedes et lyserødt bundfald. Man fortsatte omrøringen i 1/2 time ved stuetemperatur, før 25 bundfaldet blev opsamlet og vasket. Der opnåedes adskillige yderligere udbytter fra filtraterne. Produktet blev rekrystalliseret fra chloroform.
i) Fremstilling af 4-(41-benzylidenbenzoyl)-benzoesyre 11
DK 162468 B
Til en dispersion af 4-(4'-benzylidenbenzoyl)-methyl-benzoat (4,07 g) i toluen (120 ml) tilsattes en opløsning af kaliumhydroxid (0,9 g) i methanol (20 ml). Den resulterende blanding blev omrørt i 72 timer ved stue-5 temperatur. Den resulterende suspension blev extraheret adskillige gange med vand, og de vandige portioner blev kombineret, filtreret og gjort sure med 1 M H^SO^.
iii) Konvertering til benzoesyren
Til en isafkølet opløsning af 4-(4'-benzylidenbenzoyl)-10 benzoesyre (1,40 g) i THF tilsattes en opløsning af 1,1'-carbonyldiimidazol (0,7 g) i THF (10 ml), under omrøring.
Efter 2 timer tilsattes langsomt en opløsning af t-butyl-hydroperoxid (0,5 g, 80¾) i THF (10 ml). Omrøring blev fortsat i yderligere 1 time ved 0 °C, hvorefter opløsnin-15 gen blev filtreret og solventet fjernet. Den resulterende olie blev renset ved søjlekromatografi (silica) med di-chlormethan som eluent. Den resulterende, farveløse olie størknede ved afkøling natten over til dannelse af et produkt med et smeltepunkt på 72-76 °C.
20 I henhold til de i krav 4 og 6 angivne udførelsesformer for opfindelsen behøver optiske sensibiliseringsmidler generelt ikke at blive inkorporeret i det strålingsfølsomme middel. Når de er tilstede, kan sensibiliserings-midlet sammen med perester-fotoinitiator-forbindelsen ud-25 gøre op til ca. 20¾ af midlets totale vægt. Det optimale indhold af sensibiliseringsmidlet er ca. 5 vægt-* af midlet. På lignende· måde er perester-fotoinitiator-forbin-delsen eventuelt tilstede i en mængde af ca. 5¾.
Enhver additionspolymeriserbar forbindelse, der indehol-30 der ethylenisk umættethed kan·anvendes i det photopolyme-riserbare middel i den strålingsfølsomme plade ifølge opfindelsen. Man foretrækker simple forbindelser, eller mo- 12

nomere, som de undertiden kaldes, indeholdende ethylenisk umættethed, samt polymere med endegrupper eller udragende grupper termineret med ethylenisk umættethed. Det er f.eks. tilstræbt, at betegnelsen "additionspolymeriserbar forbin-5 delse" skal omfatte polymere, der har tilbagevendende enheder med strukturen
T
OC - CR = CH„ II ^ o hvor T er enhver gruppe, der kan danne skelettet.i en polymer, og R er hydrogen eller methyl.
10 Andre eksempler på brugbare additionspolymeriserbare forbindelser indeholdende ethylenisk umættethed omfatter monomere (meth)acrylater, (meth)acrylamider, ally1-forbindel-ser, vinylethere, vinylestere, N-vinyl-forbindelser, styrener, acrylonitriler og crotonater. Mange eksempler på 15 hver af disse klasser er kendte, såsom f.eks. dem, der er sammenstillet i GB patent nr. 1 534 137.
En i høj grad foretrukken klasse af additionspolymeriserbare forbindelser omfatter (meth)acrylat-forbindelserne. Særligt anvendelige eksempler omfatter alkyl-(meth)acry-20 later med fra 1 til 30 og især 1 til 5 carbonatomer i al- kyldelen, såsom methyl- og ethy1-(meth)acrylat; pentaery-thritol-tri- og tetra-(meth)acrylater; estere af polyoler, herunder glycol-di(meth)acrylater, såsom tripropylenglycol-diacrylat, tetraethylenglycol-diacrylat og triethylengly-25 col-dimethacrylat; alkandiol-di(meth)acrylater; urethan- (meth)acrylater, såsom reaktionsprodukterne af hydroxyl-gruppeholdige (meth)acrylater med di- eller poly-isocya-nater; epoxy-(meth)acrylater; og blandinger af de før angivne.

Tilsætningen til det photopolymeriserbare middel af en polymer binder er ønskelig for at styrke midlet og for at forbedre adhæsionen af midlet til substratet. Typiske bindere er acryliske polymere, v/inylacetat-polymere og novo-5 lak-harpikser. Mange eksempler på passende polymere er opført i patentlitteraturen, og der kan f.eks. henvises til US patent nr. 3 652 275 og 4 268 667 og GB publiceret patentansøgning nr. 2 006 775·. Binderen kan foreligge i en mængde op til mængden af den polymeriserbare forbindelse.
10 Som bekendt bliver polymerisationen af vinylgruppeholdige monomere inhiberet ved tilstedeværelsen af oxygen. Det er derfor ønskværdigt, at man over overtrækket af det photopolymeriserbare middel tilvejebringer et barrierelag, som er transparent for stråling og også impermeabelt for oxy-15 gen. Et lag af polyvinylalkohol er særligt velegnet til dette formål.
Substratet kan være ethvert substrat, der konventionelt anvendes med photoresist eller ved produktion af litografiske trykplader, og et substrat dannet af marmoreret og 20 -anodiseret aluminium er særligt foretrukket.
De følgende eksempler skal illustrerer opfindelsen.

Man gentog eksempel 1 under anvendelse af 4(1'methoxyben-5 zoyl)-t-butyl-perbenzoat som initiator. Lignende resulta ter opnåedes med undtagelse af, at den strålingsfølsomme plade var følsommere, idet der ved fremkaldelse frembragtes en trinkile med karakteren fast 5, hale 9.
EKSEMPEL 4 10 Eksempel 1 blev gentaget, med undtagelse af, at Ethyl
Michler's keton blev erstattet med 0,15 vægtdele 2,6-bis(4'-diethylaminobenzyliden-)cyclohexanon som optisk sensibiliseringsmiddel, og pladen exponeret i 20 sekunder for lys fra en xenonbue gennem et Wratten 45 filter, 15 der transmitterer lys i området 440-540 nm. Det fremkaldte billede havde en trinkile med karakteren fast 5, hale 13.
Når dette sensibiliseringsmiddel blev udeladt fra overtrækket, frembragte den resulterende plade ikke noget billede, når den blev exponeret under lignende betingelser.
