Изобретение относитс к реставрации документов, в частности с способам обработки документов на бумажном .носителе при их реставрации, сопр женной с влажной обработкой документа , т.е. его обработкой в водной среде.The invention relates to the restoration of documents, in particular with methods of processing documents on a paper carrier during their restoration, coupled with wet processing of the document, i.e. its treatment in the aquatic environment.
Целью изобретени вл етс повышение удержани текстов и изображений вьшолненных чернилами или штемпельной краской на основе кислотных анилиновых красителей.The aim of the invention is to increase the retention of texts and images made in ink or ink on the basis of acidic aniline dyes.

В таблице приведены качественные показатели по фиксации чернил на бумаге, отобранной по предлагаемому и известному способам.Example 4. Operations are carried out analogously to example 3. But a 3.5% solution of chitosan acetate is prepared and applied, drying is carried out at a temperature of 70 ° C for 1.5 minutes. The table shows the quality indicators for fixing ink on paper, selected by the proposed and known methods.
Экспериментальные данные свидетельствуют о том, что по предлагаемому способу обеспечиваетс удержание черных чернил на основе кислотExperimental data indicate that the proposed method ensures the retention of acid-based black ink.

Одним из известных способов определ ют, какими именно чернилами выполнены надписи на этом документе (предпочтительно пользоватьс способами, примен емыми в криминалистических лаборатори х).

One of the known methods is used to determine exactly which ink is written on this document (it is preferable to use the methods used in forensic laboratories). If it is determined that the inscriptions are made with inks based on acidic aniline dyes, 1.5% 98% are prepared, 92.8-94.0% stamp inks, 84.4% –95.9% inks in ink, and up to 72%, i.e. significantly higher than in the known method.
Таким образом,применение предлагаемого способа приводит к упрочнению документа, что особенно важноThus, the application of the proposed method leads to hardening of the document, which is especially important

The prepared solution is applied to ink on the document, for example, with a brush. Then the document is dried, for example, on an electrolyzer at a temperature of 75 ° C for 1 minute. Then the document is restored by one of the known methods involving its treatment in the aquatic environment.
