Description

【発明の詳細な説明】 本発明は銀画像の漂白方法及びそのための溶液に関する。[Detailed description of the invention] The present invention relates to a method for bleaching silver images and a solution therefor.

写真ハロゲン化銀画像形成プロセスはよく知られている。それによって形成され た銀画像を修正したいことは時々あり、特に不所望のスポットの画像の部分を除 去したいことは時々ある。Photographic silver halide imaging processes are well known. formed by it Sometimes you may want to modify a silver image, especially removing parts of the image with undesirable spots. Sometimes there are things I want to leave behind.

例えば英国特許明細書第2107889号から、例えば沃素及び沃化物を含む濃 厚溶液が所望の結果を達成することができることは知られている。このアプロー チの問題は目に見えない茶褐色汚染が生ずることである。更に英国特許明細書第 2107889号の組成物はゼラチン層を有さない印刷版用に適するに過ぎない 。それ故、如何なる汚染(3tain)を引き起こすことなく銀画像を除去し、 かつゼラチン含有量の銀画像を除去することができることが望まれている。For example, from British Patent Specification No. 2107889, concentrations containing e.g. iodine and iodides. It is known that thick solutions can achieve the desired results. This approach The problem with this is that it creates invisible brown contamination. Furthermore, British Patent Specification No. The composition of No. 2107889 is only suitable for printing plates without a gelatin layer. . Therefore, remove the silver image without causing any stain, It would also be desirable to be able to remove gelatin-containing silver images.

本発明は如何なる汚染も起こすことなく銀画像を除去する方法を提供する。The present invention provides a method for removing silver images without causing any contamination.

本発明に従えば、銀画像を沃素及び沃化物塩を含む第一の溶液で処理し、次に沃 素汚染をアスコルビン酸及び亜硫酸イオンを含む第二の溶液で処理することによ って除去する銀画像の漂白方法が提供される。In accordance with the present invention, a silver image is treated with a first solution containing iodine and an iodide salt; The primary contamination is treated with a second solution containing ascorbic acid and sulfite ions. A method of bleaching a silver image is provided.

この画像は迅速かつ永久的に漂白され、汚染は起こらず、そして前記第−及び第 二の溶液は長い寿命を有する。This image is quickly and permanently bleached, no staining occurs, and the The second solution has a long life.

処理すべき銀画像は像状露光され完全に処理された写真フィルムもしくは紙上又 は写真銀塩拡散転写プロセスによって作られた印刷版上に位置するものとするこ とができる。このような材料はリサーチディスクロージ+−(Reserch  Disclosure)項目308119 (1989年12月発行、 Ken neth Mason Publications、 Emsworth、 H ants、英国)。The silver image to be processed is imagewise exposed and fully processed on photographic film or paper. shall be located on a printing plate made by a photographic silver salt diffusion transfer process. I can do it. Such materials are available from Research Disclosure +- (Research Disclosure) Item 308119 (Published December 1989, Ken neth Mason Publications, Emsworth, H ants, UK).

本発明の好ましい態様においては、前記第−及び第二の溶液はフェルトチップペ ン(felt tipped pen)、好ましくは正確な適用ができるような 繊細なチップを有するものを用いて銀画像に適用することができる。In a preferred embodiment of the invention, the first and second solutions are made of felt tip paste. a felt-tipped pen, preferably one that allows for precise application. Can be applied to silver images using those with delicate tips.

第一の溶液は、銀画像の除去に用い、好ましくは水及びブチロラクトンの混合物 を含む。この有機溶媒に対する水の比率は画像保存材料上のゼラチン層中へ溶質 が急速に浸入するのに十分な水を与えるように、かつ画像を都合よく早い時間で 除去できるように沃化銀に対する高い錯生成力を得るのに十分なブチロラクトン を与えるように最適化される。第一の溶液は、他の溶媒、例えばエチル又はブチ ルアルコールのようなアルコールなどを単独又は組み合わせて使用することもで きる。The first solution is used for silver image removal and is preferably a mixture of water and butyrolactone. including. This ratio of water to organic solvent allows the solute to enter the gelatin layer on the image storage material. to give enough water for rapid infiltration, and to image at a conveniently early time. Sufficient butyrolactone to obtain high complexing power for silver iodide such that it can be removed is optimized to give The first solution may be mixed with another solvent, such as ethyl or butylene. Alcohols such as alcohol can also be used alone or in combination. Wear.

沃化物はアンモニウムの沃化物又はアルカリ金属の沃化物(例えば沃化ナトリウ ムもしくはカリウム)などの沃化物とすることができる。Iodides are ammonium iodides or alkali metal iodides (e.g. sodium iodide). It can be an iodide such as aluminum or potassium).

第一の溶液は、好ましくは、リットル当り、2〜50g、特に20〜45gの沃 素及び50〜250 g 、特に150〜200gの沃化物イオンを含むことが できる。溶媒は、好ましくは水10〜60重量%を含み、正確な数字は上に述べ たことを考慮した点に依存する。第一の溶液は湿潤剤及び酸も含むのが好ましい 。The first solution preferably contains between 2 and 50 g, especially between 20 and 45 g of iodine per liter. and 50 to 250 g, especially 150 to 200 g of iodide ions. can. The solvent preferably contains 10-60% by weight of water, the exact number being as stated above. It depends on the point taken into consideration. Preferably, the first solution also includes a wetting agent and an acid. .

第二の溶液は、好ましくは、リットル当り、10〜ioog、特に40〜80g のアスコルビン酸及び10〜100 g 、特に30〜70gの亜硫酸カリウム を含む。この溶液は水溶液が好ましい。The second solution is preferably from 10 to 80 g per litre, especially from 40 to 80 g. of ascorbic acid and 10 to 100 g, especially 30 to 70 g of potassium sulfite including. This solution is preferably an aqueous solution.

本発明は更に前に定義した第−及び第二の溶液を含む削除液キットを提供する。The invention further provides a deletion solution kit comprising a first and second solution as defined above.

これらの溶液はそれぞれフェルトチップペンに含ませるのが好ましい。 ゛ 以下の例は本発明のより良い理解のために含ませるものである。Preferably, each of these solutions is contained in a felt tip pen.゛ The following examples are included for a better understanding of the invention.
