The invention relates to a printed hemostatic product having at least three-dimensions and being made of a stack of layers deposited on one another from a first external layer up to a second external layer, wherein adjacent layers of the stack of layers are joined together, and wherein at least one layer of the stack of layers has at least one portion made from an hemostatic flowable with a composition comprising: non-cross-linked collagen of the fibrillar type comprising a content of fibrous collagen and/or fibrillar collagen of at least 70% by weight relative to the total weight of the collagen; and—at least one monosaccharide. The invention also relates to a method for forming such an hemostatic product with a three-dimensional additive printer, and the use of an hemostatic flowable as a printing ink in such a three-dimensional additive printer.

Provided is an inkjet composition for printing an indelible colorant onto a substrate. Also provided is a method of printing using the inkjet composition, and a printed substrate obtainable and obtained from the method of printing. The inkjet composition has an indelible colorant, one or more solvents, and a binder. The migration distance of the indelible colorant in the substrate is less than 0.85 mm after 7 days at 25° C. The composition may be used to provide indelible markings in the surface of the substrate, and these markings do not significantly disperse over time.
