The field of the invention is that of fluorescence spectroscopic methods. In particular, the present invention relates to a fluorescence spectroscopic method and to several products that can be analyzed using this method.

Fluorescence spectroscopic method using polyester composition containing additive to prevent oxidative degradation, and substrate, optical filter, security document, and sensor device containing the polyester composition

The invention relates to a polyester film comprising, on at least one of the faces thereof, a scratch-resistant crosslinked coating. The objective of the invention is to provide a polyester film coated with an abrasion-resistant layer which adheres perfectly to the polyester substrate, and is simple and economical to manufacture. To achieve this objective, the crosslinked hard coating applied to the polyester film comprises: i. 20% to 99% by weight of at least one ester and/or one amide of (meth)acrylic acid comprising a substituted protic group; ii. 20% to 99% by weight of acrylic resin(s); iii. 1% to 40% of a polyalkylene diacrylate; iv. 0 to 50% of at least one derivative of the benzophenone family; v. 0 to 5% of at least one photoinitiator. The invention also relates to the method for obtaining this polyester film coated with an abrasion-resistant hard layer. Use in the production of polyester/metal sheet (steel) colaminate.

Silicone composites subject to reticulation or reticulated, particularly for creating a coating or water-repellent and anti-adhesive film for flexible substrates such as paper or similar in the form of natural or synthetic polymer films. These compounds contain reticulating polyorganosiloxanes that have SiH units and unsaturated polyorganosiloxanes, preferably vinylated, suitable for reacting with the reticulating agent in an addition reaction and in the presence of platinum to form the reticulated anti-adhesive coating on the flexible substrate, plus at least one additive (D) to promote adhesion to it. A new liquid silicone compound can be applied without using a solvent, which is beneficial, that can be reticulated instantly to produce an anti-adhesive and/or water-repellent coating for the flexible substrate, giving very high quality reticulated silicone coatings, particularly in terms of sticking/adhering to the substrate, being harder to rub off and the anti-adhesion profile (sufficiently increase detaching force at high speed.

The invention relates to the field of silicon resins, particularly polymethylvinylsiloxane resins. The invention more specifically relates to a method for the production of polymethylvinylsiloxane resins comprising at least two different types of siloxy motifs RSiO(motif M) and SiO(motif Q, optionally Q), said method comprising the following steps: a) producing a siloxane resin comprising motifs Q by acidic hydrolysis of a siloxane resin precursor, preferably an alkaline silicate; b) functionalizing the siloxane resin obtained in step a) with halogenosilanes in the presence of an apolar solvent, the functionalizing generating sub-products including volatile oligosiloxanes (silox); c) recovering silox produced in step b) in a solution in the apolar solvent; and d) subjecting the resin functionalized in step b) to rearrangement with the aid of a strong base in order to eliminate the silanols, wherein at least a part of the silox produced during step b) and recovered in step c) is recycled.
