Description
Przy technicznem przeprowadzeniu sposobu sporzadzania negatywów z orygi¬ nalów, które nie dozwalaja na przeswietle¬ nie, jako podkladki do kopjowania do fo¬ tolitografii, okazalo sie nieprzyjemne zja¬ wisko* Rozpuszczalne w wodzie barwiki anilinowe, za posrednictwem których war¬ stwa koloidynowo-chromatyczna, pozosta¬ jaca na plycie po wywolaniu, staje sie nie¬ przepuszczalna dla swiatla, przez lezenie w wodzie odbarwialy sie, wskutek tego obrazy stawaly sie niewyrazne i musialo sie je dobarwic. Sprawialo dalej wielka trudnosc pokrycie wysuszonego negatywu preparatami, zawierajacemi wode (np. roz¬ twór zelatyny) bez narazenia sie na to, ze¬ by naniesione warstwy przyjely barwiki negatywu.Te niedogodnosci usuwa wynalazek, który polega na tern, ze przemienia sie u- zyte barwiki zasadowe lub kwasowe na nie¬ rozpuszczalne polaczenia. Wiadomo, ze zasadowe i kwasne barwiki moga byc za¬ mienione na nierozpuszczalne w wodzie za- pomoca pewnych soli lub kwasów, wzglednie zasadowych cial o charakterze barwików.Tak np. difenol kwasu diamidostilben disiilfonowego (diamidostilbendisulfosaure- diphenol), w wodnym roztworze daje nie¬ rozpuszczalny w wodzie osad z rozcienczo- nemi wodnemf roztworami pentametyl-p- rozaniliny.Wykonanie nowego sposobu jest naste¬ pujace: Azeby zrobic chromiano-kolloidowy ne¬ gatyw, nieprzepuszczalny dla wody, wkla¬ da sie go w celu zabarwienia do rozcienczo¬ nego roztworu pentametyl-p-rozaniliny,Aapie sie nastepnie zabarwiony negatyw w rozcienczonym wodnym roztworze difeno- lu kwasu diamidostilbendisulfonowego (dia- midostilbendisulfosaurediphenol). W ten sposób tworzy sie warstwa chromiano-kol- loidowa nierozpuszczalnego w wodzie laku barwnego, tak, ze podczas lezenia negaty¬ wu w wodzie nie nastepuje odbarwienie, a równiez przy walcowaniu cieplemi roz¬ tworami zelatyny ta ostatnia nie zabarwia sie. PLIn the technical implementation of the process of producing negatives from originals that do not allow for exposure as photolithography copying pads, an unpleasant phenomenon has turned out to be an unpleasant phenomenon. Water-soluble aniline dyes, through which the colloidin-chromatic layer is remaining on the plate after development, it becomes impervious to light, by lying in water they become discolored, as a result of which the images became indistinct and had to be colored. It was further difficult to cover the dried negative with preparations containing water (e.g. gelatin solution) without the risk that the applied layers would take on the negative's colors. These inconveniences are overcome by the invention, which consists in transforming the used basic or acid dyes for insoluble combinations. It is known that basic and acidic dyes can be replaced with water-insoluble by certain salts or acids, or relatively basic dye-like bodies. For example, diphenol of diamidostilbene disilonic acid (diamidostilbendisulfosaure-diphenol) in aqueous solution gives no a water-soluble precipitate with a dilute aqueous solution of pentamethyl-p-rosaniline. The implementation of the new method is as follows: To make a chromium-colloid negative, impermeable to water, it is added to the diluted solution for coloration. pentamethyl-p-rosaniline, Aapie is then dyed negative in a dilute aqueous solution of diamidostilbendisulfonic acid diphenol (diamidostilbendisulfosaurediphenol). In this way, a chromium-colloid layer of the water-insoluble colored lacquer is formed, so that no discoloration occurs when the negative is poured in water, and the latter does not become discolored when rolled with warm gelatine solutions.
