Embodiment 1

[0213] This example illustrates the manufacture of decorated natural leather in which the leather is attached to an adhesive-coated plastic foil.

[0214] Preparation of Pigmented UV Curable Inkjet Inks

[0215] Concentrated pigment dispersions CPC, CPM1, CPM2, CPY and CPK are first prepared. These concentrated pigment dispersions were then used to prepare Table 7 A set of pigmented UV curable inkjet inks.

[0216] Concentrated Cyan Pigment Dispersion CPC

[0217] Use DISPERLUX from DISPERLUX S.A.R.L., Luxembourg TM disperser, by mixing according to Table 2 Components for 30 minutes to prepare a concentrated pigment dispersion. The dispersion was then milled with a Bachofen DYNOMILL ECM mill filled with 0.4 mm yttrium stabilized zirconia beads ("High Abrasion Resistant Zirconia Milling Media" from TOSOH Co.). The mixture was circulated on the grinder for 2 hours. After grinding, drain the concentrated pigment dispersion through a 1 μm filter into a container. Tabl...

Embodiment 2

[0256] This example illustrates the manufacture of decorated natural leather in which the leather is attached to the paper foil using a spray adhesive.

[0257] Preparation of upholstered leather LS2

[0258] Spray adhesive (Scotch-Welder 77 from 3M) was sprayed onto the leather side of A4 size calfskin half-tanned leather pieces from NUTI IVO, Santa Crocesull'Arno. The semi-tanned leather is then applied with its leather side to A3 size kraft paper. LS2 is written on vellum not covered by leather with black markings as identifiers. Then cover the identifier with a piece of scotch tape.

[0259] The kraft paper and semi-tanned leather assembly was spray coated with a white base coat BC1 using a spray test microgun from WALTHER PILOT and dried at a temperature of 60°C.

[0260] Positioning of painted assemblies on a flatbed inkjet printer Jeti from AGFA GRAPHICS NV TM One of the six vacuum zones of the Mira LED and a decorative image printed using the pigmented UV-curabl...

Abstract

A manufacturing method of decorated natural leather including the steps of: attaching a crusted leather (45) with its corium side by an adhesive (46) to a temporary carrier (47); inkjet printing the crusted leather (45) on its grain side with one or more pigmented inkjet inks; wherein the surface area of the temporary carrier (47) is larger than the surface area of the crusted leather (45).

Description

technical field [0001] The present invention relates to the manufacture of decorative natural leather and leather articles utilizing the same. Background technique [0002] Businesses today are increasingly focused on the individual customer experience. Customization has transformed into personalization, as from Coca-Cola TM Everything from cans to shoes is personalized. This presents great challenges in terms of smoothing the buying process and logistics chain, and this is certainly true for the business of leather goods such as leather car seats, shoes and handbags. [0003] The manufacture of natural leather goods is well known and can generally be divided into five stages as figure 1 shown. Preparatory stage 1 usually takes place partly at the slaughterhouse and partly at the tannery, while stages 2 to 4 take place at the tannery and stage 5 takes place at the leather goods manufacturer. In the first stage, the preparation stage, the hide is removed (skinned) from t...
