13.07.2018
Revision of the third edition of Technical Knowledge folder: Dyes, optical brightening agents.

Technical Knowledge folder no. 3 "Dyes, optical brightening agents – Permanency of paper and board" has been completely revised in recent months and supplemented by a literature index.

Optical brightening agents convert near UV radiation that is not visible to the human eye to visible fluorescence radiation in the violet-blue spectral range (400 to 480 nm). They improve the whiteness of papers in this way. Discover the physio-chemical principles of optical brightening agents and learn how to classify them for the preservation of cultural artefacts.

A digital version or printed version of the Technical Knowldege folder is available. For further questions please do not hesitate to contact us by phone at +49 (0)8323 9653 30 or by e-mail.
