Definitions
- the present invention relates to the field of securing and authenticating products. More particularly, the invention relates to a fluorescent composition for securing and authenticating products such as identity, fiduciary and administrative documents.
- various companies provide visual authentication solutions, for example using holograms or laser engravings, which can allow the insertion of information about a plastic card body such as an identity card, health card or driver's license.
- Document EP0708935 A1 describes for example a set of holographic protection layers.
- This assembly consists of a support film having at least one layer formed by a protective varnish, a reflective or transparent layer bearing a diffracting microstructure, and finally, an adhesive layer.
- a protective varnish a protective varnish
- a reflective or transparent layer bearing a diffracting microstructure
- an adhesive layer a layer formed by a protective varnish
- a reflective or transparent layer bearing a diffracting microstructure a reflective or transparent layer bearing a diffracting microstructure
- an adhesive layer Once the set of layers has been transferred to a document, the latter is secured.
- this system was then improved by means of perforations making it more difficult the separation of the different layers.
- the set of layers, even perforated consists of a multitude of parts that it is necessary to assemble which represents additional constraints in terms of time and cost.
- Document FR 16 50164 of which the Applicant is the holder, describes the use of a compound of the family of 4,4-difluoro-4-bora-3a, 4a-diaza-s-indacenes for the preparation of an element for securing a product, in particular a document, said securing element comprising a polymer and the compound being incorporated into said polymer.
- the use of the compounds described only allows fluorescence emissions to be obtained within the range from 500 nm to infrared, and thus does not cover the entire range of the visible spectrum.
- Application US 2008/0081913 A1 describes compounds of benzoxazole and benzothiazole type exhibiting fluorescent properties and having utility in particular as authentication compounds in data storage media and data storage substrates.
- level 1 security elements are elements that can be detected by at least one of the five senses or through a contrasting background.
- level 1 security elements are elements that can be detected by at least one of the five senses or through a contrasting background.
- optical variability devices such as iridescent prints, holograms, optically variable inks ("Optical Variable Ink”), markers, variable laser images ("Changeable Laser Image”) or again the multiple laser images (“Multiple Laser Image”).
- the level 2 security elements are elements that can be detected by means of simple equipment such as an Ultra-Violet lamp, a convex lens or even a flash light from a mobile phone. Detectable elements such as micro-prints, fluorescent inks, as well as fluorescent fibers or plates are found in this level.
- the level 3 security elements are elements detectable by means of sophisticated equipment such as for example a spectrofluorimeter or an electron microscope. In this category are found in particular nano-engraved pigments, biometric chips as well as fluorescent markers not detectable with the naked eye (in English: taggants).

- the fluorescent layer thus obtained is a secure layer.
- a UV lamp 365 nm
- a purple fluorescence appears to the naked eye.
- Visual and spectrophotometric analysis of the secure layer shows that the incorporation of the fluorescent dye into the polycarbonate does not affect its performance in terms of fluorescence absorption and emission.
- Example 3 Preparation of a fluorescent composition in ink form comprising a compound of formula I according to the invention and a compound of formula III.
- Compound 27 is in the form of a white powder, absorbs at 365 nm, has fluorescence emission at 522 nm.

- Preparation of the fluorescent composition in ink form 400 mg of compound 27 are uniformly dissolved in 100 g of transparent virgin screen printing ink of the Mara® Gloss GO type distributed by the Marabu company, compatible with printing on a plastic surface. in polycarbonate. 100 mg of compound 36 are uniformly dissolved in 100 g of the same transparent virgin screen printing ink. The ink containing the compound 27 and the ink containing the compound 36 are then mixed in a ratio of 1: 1 by weight.
- the fluorescent composition thus formulated is printed on a transparent polycarbonate card.
- Results The fluorescent composition printed perfectly.
- the pattern thus printed has a pink color visible by transparency when said card is placed on a white background, and an orange color visible by transparency when said card is placed on a black background.
- Example 4 Preparation of a fluorescent composition in ink form comprising a compound of formula I according to the invention
- the compound of family I used is compound 3 of formula below:
- Compound 3 is in the form of a white powder, absorbs at 365 nm, has fluorescence emission at 513 nm.
- the fluorescent composition thus formulated is printed on a transparent polycarbonate card using a 90 mesh screen printing frame.
- the pattern thus printed is invisible under ambient lighting and has an intense yellow fluorescence under UV lighting (365 nm).
- the optical properties of the dye are transposed between the pure dye and the screen printed layer.
- Example 5 Preparation of a fluorescent composition in ink form comprising a compound of formula I according to the invention
- the compound of formula I used is compound 13 of formula below: [0212] [Chem. 10] [0213] Compound 13 is in the form of a white powder, absorbs at 365 nm, has fluorescence emission at 605 nm.
- the fluorescent composition thus formulated is printed on a transparent polycarbonate card using a 90 mesh screen printing frame.
- the pattern thus printed is invisible under ambient lighting and has a red fluorescence under UV lighting (365 nm).
- the optical properties of the dye are transposed between the pure dye and the screen printed layer.
- 400 mg of compound 3 are uniformly dissolved in 100 g of transparent virgin screen printing ink of the Mara® Gloss GO type distributed by the Marabu company, which is compatible with printing on a polycarbonate plastic surface. 400 mg of compound 13 are uniformly dissolved in 100 g of the same transparent virgin screen printing ink.
- Results The fluorescent composition printed perfectly.
- the pattern thus printed is invisible under ambient lighting and has an intense orange fluorescence under UV lighting (365 nm).
- the color thus obtained refers to the mixture of the respective fluorescence colors of the two dyes.
