Polish scientists discover new substance to protect old prints

Scientists from the University of Silesia (UŚ) have developed new compounds - quinoline derivatives - used to disinfect old prints and protect them against fungi. The preparation can also be used on wooden surfaces, such as picture frames. The solution has been protected by a patent.

The preparation can be used in standard methods of disinfecting book collections. “Most often, in antique prints, the least invasive methods are used, which consist of spraying sheets, lubricating, padding or the method of spacers. Unless the book is so damaged and infected that the pages fall apart, then the entire collection is disassembled and baths are taken, but this is a very time-consuming job”, said Dr. Bangrowska, co-author of the patent.

Some companies have already expressed an interest in the new method.
