The articles comprise an adhesive having specific Theological properties that provide increased efficacy in capturing and trapping large particles and hairs. ## Claims ### Claim 1 A hard surface cleaning article comprising sheet further comprising an adhesive having: a. An elastic modulus G′25 measured at 25° C. and 0.1 rad/s below 15000 Pa, and b. An elastic modulus percent increase ΔG′25 measured between 0.1 and 100 rad/s of more than 100%; wherein said adhesive is an oil gel and comprises from about 75% to 95% by weight of a plasticizer selected from the group consisting of vegetable oils, epoxidized and polymerized derivatives of vegetable oils, monocarboxylic fatty acids (C8-C22), and their derivatives and from about 1% to about 48.5% by weight of a tackifier selected from the group consisting of hydrocarbon resins; aliphatic resins; terpene and terpene-phenolic resins; aromatic and aromatically modified resins; synthetic C5 resins, C5-C9 resins and mixtures thereof having a softening point of 160° C. or less, wherein said adhesive is present in a recessed area of said article and said adhesive does not directly contact the surface to be cleaned, wherein the sheet comprises at least three layers comprising a layer of said adhesive sandwiched between fabric layers, wherein at least one of the fabric layers has holes. ### Claim 2 (depends on 1) A hard surface cleaning article according to claim 1, wherein said adhesive has a crossover frequency of less than 1000 rad/s. ### Claim 3 (depends on 1) A hard surface cleaning article according to claim 1, wherein said adhesive is a hot melt adhesive. ### Claim 4 (depends on 1) A hard surface cleaning article according to claim 1, wherein said adhesive comprises from 0.5% to 49% by weight of a polymer or mixture of polymers. ### Claim 5 (depends on 1) A hard surface cleaning article according to claim 1, wherein said sheet comprises a polymeric film. ### Claim 6 (depends on 1) A hard surface cleaning article according to claim 1, wherein said sheet comprises a nonwoven. ### Claim 7 (depends on 6) A hard surface cleaning article according to claim 6 wherein said sheet comprises peaks and valleys. ### Claim 8 A hard surface cleaning article comprising a sheet and further comprising an adhesive disposed on said sheet, said adhesive having: an oil gel and comprising from about 75% to 95% by weight of a plasticizer selected from the group consisting of vegetable oils, epoxidized and polymerized derivatives of vegetable oils, monocarboxylic fatty acids (C8-C22), and their derivatives and from about 1% to about 48.5% by weight of a tackifier selected from the group consisting of hydrocarbon resins; aliphatic resins; terpene and terpene-phenolic resins; aromatic and aromatically modified resins; synthetic C5 resins, C5-C9 resins and mixtures thereof having a softening point of 160° C. or less, wherein said adhesive is present in a recessed area of said article and said adhesive does not directly contact the surface to be cleaned, wherein the sheet comprises at least three layers comprising a layer of said adhesive sandwiched between fabric layers. ### Claim 9 (depends on 8) A hard surface cleaning article according to claim 8 wherein said sheet comprises a nonwoven. ### Claim 10 (depends on 8) A hard surface cleaning article according to claim 8 wherein said sheet comprises a nonwoven having peaks and valleys and said adhesive is disposed only in said valleys. ### Claim 11 (depends on 8) A hard surface cleaning article according to claim 8 wherein said adhesive has a modulus G′25 measured at 25° C. and 0.1 rad/s below 15000 Pa. ### Claim 12 (depends on 8) A hard surface cleaning article according to claim 8 wherein sais adhesive has an elastic modulus percent increase ΔG′25 measured between 0.1 and 100 rad/s of more than 100%. ### Claim 13 A hard surface cleaning article comprising a sheet and further comprising an adhesive disposed on said sheet, said adhesive having: an oil gel and comprising from about 75% to 95% by weight of a plasticizer selected from the group consisting of vegetable oils, epoxidized and polymerized derivatives of vegetable oils, monocarboxylic fatty acids (C8-C22), and their derivatives and from about 1% to about 48.5% by weight of a tackifier selected from the group consisting of hydrocarbon resins; aliphatic resins; terpene and terpene-phenolic resins; aromatic and aromatically modified resins; synthetic C5 resins, C5-C9 resins and mixtures thereof having a softening point of 160° C. or less, wherein said adhesive is present in a recessed area of said article and said adhesive does not directly contact the surface to be cleaned, wherein the sheet comprises at least three layers comprising a layer of said adhesive sandwiched between fabric layers, wherein said sheet comprises at least one of a nonwoven and a polymeric film. ### Claim 14 (depends on 13) A hard surface cleaning article according to claim 13 wherein said adhesive is a hot melt adhesive. ### Claim 15 (depends on 13) A hard surface cleaning article according to claim 13, wherein said adhesive comprises from 0.5% to 49% by weight of a polymer or mixture of polymers. ### Claim 16 (depends on 13) A hard surface cleaning article according to claim 13 further comprising a cleaning lotion. ### Claim 17 (depends on 13) A hard surface cleaning article according to claim 13 further comprising a wax.
