Another subject of the invention is the use of the packaging article for dyeing keratin fibers, and a process for dyeing keratin fibers using the said article. The use of the packaging article makes it possible to obtain dye compositions having good dyeing properties, which are easy to apply and which make it possible to obtain powerful coloring of the hair. ## Claims ### Claim 1 A packaging article comprising: i) an envelope defining at least one cavity, the envelope comprising water-soluble and/or liposoluble fibers; ii) at least one anhydrous dye composition comprising at least one oxidation dye; and iii) at least one anhydrous oxidizing agent; wherein the dye composition ii) and the oxidizing agent iii) are in the at least one cavity defined by the envelope i). ### Claim 2 (depends on 1) The packaging article of claim 1, wherein the anhydrous dye composition and/or the anhydrous oxidizing agent are in paste or powder form. ### Claim 3 (depends on 1) The packaging article of claim 1, wherein the envelope i) comprises at least one water-soluble polymer chosen from natural, artificial, or synthetic water-soluble polymer fibers. ### Claim 4 (depends on 1) The packaging article of claim 1, wherein the envelope i) comprises at least one water-soluble polymer chosen from polysaccharides. ### Claim 5 (depends on 1) The packaging article of claim 1, wherein the envelope i) comprises synthetic water-soluble polymer fibers or polyvinyl alcohol fibers. ### Claim 6 (depends on 1) The packaging article of claim 1, wherein the envelope i) is nonwoven. ### Claim 7 (depends on 1) The packaging article of claim 1, wherein the envelope i) comprises liposoluble polymer fibers. ### Claim 8 (depends on 1) The packaging article of claim 1, wherein the envelope i) comprises at least one type of fiber chosen from spun, carded or twisted fibers, wherein the at least one type of fiber has a diameter of less than about 500 μm and/or wherein the tensile strength of the at least one type of fiber is at least about 2.7 g/dtex (3 g/d). ### Claim 9 (depends on 1) The packaging article of claim 1, wherein the envelope i) comprises from about 0.5% to about 20.0% by weight relative to the total weight of the packaging article. ### Claim 10 (depends on 1) The packaging article of claim 1, wherein the dye composition ii) comprises one or more oxidation bases chosen from para-phenylenediamines, bis(phenyl)alkylenediamines, para-aminophenols, ortho-aminophenols, or heterocyclic bases, or the addition salts thereof, optionally combined with one or more couplers chosen from meta-phenylenediamines, meta-aminophenols, meta-diphenols, naphthalene-based couplers, heterocyclic couplers, or the addition salts thereof. ### Claim 11 (depends on 1) The packaging article of claim 1, wherein the at least one anhydrous oxidizing agent iii) is chosen from at least one of a) urea peroxide, b) polymer complexes that can release hydrogen peroxide, chosen from polyvinylpyrrolidone/H2O2 complexes;

wherein the cavity comprises the dye composition comprising at least one oxidation dye; wherein at least a portion of the peripheral region is closed. ### Claim 15 (depends on 14) The packaging article of claim 14, further comprising at least one third water-soluble or liposoluble layer, wherein the third layer at least partially defines at least one additional cavity, wherein least one other ingredient is present in the at least one additional cavity and separated from the anhydrous dye composition. ### Claim 16 (depends on 14) The packaging article of claim 14, wherein the first layer and the second layer each have a thickness smaller than their other dimensions. ### Claim 17 (depends on 14) The packaging article of claim 14, wherein the first layer is a nonwoven and the second layer is a nonwoven; wherein at least one portion of the peripheral region of the first layer is substantially identical in shape to at least one portion of the peripheral region of the second layer. ### Claim 18 A process for dyeing keratin fibers, the process comprising: mixing a packaging article with a composition that is capable of dissolving the packaging article to form a resulting composition, the packaging article comprising: i) an envelope defining at least one cavity, the envelope comprising water-soluble and/or liposoluble fibers; ii) at least one anhydrous dye composition comprising at least one oxidation dye; and iii) at least one anhydrous oxidizing agent; wherein the anhydrous dye composition ii) and the oxidizing agent iii) are in the at least one cavity defined by the envelope i); applying the resulting composition to the keratin fibers; leaving the resulting composition on the keratin fibers; rinsing the keratin fibers; and optionally shampooing, rinsing, and/or drying the keratin fibers. ### Claim 19 (depends on 18) The process of claim 18, wherein the weight ratio of the packaging article to the composition that is capable of dissolving the packaging article ranges from about 10/90 to about 50/50. ### Claim 20 (depends on 18) The process of claim 18, wherein the composition that is capable of dissolving the packaging article contains an oxidizing agent.
