According to GlobalData’s company profile on Agfa-Gevaert, Document anti-counterfeiting was a key innovation area identified from patents. Agfa-Gevaert's grant share as of September 2023 was 85%. Grant share is based on the ratio of number of grants to total number of patents.
A recently filed patent (Publication Number: US20230279251A1) describes an aqueous particle dispersion that includes a polymer and a Si—O-containing moiety. The dispersion forms a solid mixture with the polymer and can be used in various applications such as inkjet inks and treatment liquids for inkjet printing.
The aqueous particle dispersion consists of a compound with a Si—O-containing moiety, which is part of a solid mixture with the polymer. In some embodiments, the dispersion includes capsules with a core and a shell, where the shell is made of the polymer. The polymer can be selected from a group of polymers including polyureas, polyurethanes, polyurea-urethanes, polyesters, polycarbonates, polyamides, melamine-based polymers, and mixtures thereof.
The dispersion may also include a compound with a Si—O-containing moiety of a specific formula, or a Si—O-containing moiety linked to the polymer. Additionally, a dispersing group can be covalently bonded to the polymer, which can be a carboxylic acid or salt thereof, a sulfonic acid or salt thereof, a phosphoric acid ester or salt thereof, or a phosphonic acid or salt thereof. Other dispersing groups can include a protonated amine, a protonated nitrogen-containing heteroaromatic group, a quaternized tertiary amine, a N-quaternized heteroaromatic group, a sulfonium, or a phosphonium.
The patent also describes the use of the aqueous particle dispersion in inkjet inks and treatment liquids for inkjet printing. The inkjet inks include a colorant along with the dispersion, and may further include a water-soluble organic solvent. The colorant can be a pigment. The treatment liquids, on the other hand, solely consist of the aqueous particle dispersion and can be used in inkjet printing processes.
Furthermore, the patent outlines an inkjet recording method that involves jetting the inkjet ink onto a substrate and drying it by applying heat. Prior to jetting the ink, an aqueous treatment liquid containing a flocculating agent, such as a multivalent salt or a cationic polymer, can be applied to the substrate.
In summary, the patent describes an aqueous particle dispersion that includes a polymer and a Si—O-containing moiety, which can be used in various applications such as inkjet inks and treatment liquids for inkjet printing. The dispersion forms a solid mixture with the polymer and can be combined with a colorant and other additives to create inkjet inks. Additionally, the dispersion can be used as a treatment liquid in inkjet printing processes.
