The record book is formed from successively numbered pages, showing the sequential number of the page and the total number of pages. The page number is printed on the page so that it is difficult to alter or forge the page number. The page number is printed in a photo-luminescent ink with an atypical optical component, or with a multiple active optical components, with the re-emission spectrum of one at least of the active optical components corresponding partly at least to the absorption spectrum of another of the active optical components. |
