1. A backing for an abrasive article comprising a sheet-like polymeric substrate having a first major surface including a pattern of non-abrasive raised areas and depressed areas for supporting an abrasive coating at least over said raised areas and an opposite second major surface including a plurality of shaped engaging elements formed of the same polymeric material as the substrate that are one part of a two-part mechanical engagement system, said shaped engaging elements being selected from the group consisting ofa) filament stems having flattened or rounded distal ends unitarily shaped into said second major surface and b) hook elements unitarily shaped into said second major surface. 2. The backing of claim 1 wherein said pattern on said first major surface is a uniform pattern.3. The backing of claim 1 wherein said shaped engaging elements comprise filament stems having flattened distal ends integrally shaped into said second major surface.4. The backing of claim 1 wherein said shaped engaging elements comprise hook elements integrally shaped into said second major surface.5. An abrasive article comprising:a) a backing comprising a sheet-like polymeric substrate having a first major surface, including a pattern of non-abrasive raised areas and depressed areas for supporting an abrasive coating at least over said raised areas and an opposite second major surface including a plurality of shaped engaging elements formed of the same polymeric material as the substrate that are one part of a two-part mechanical engagement system, said shaped engaging elements being selected from the group consisting of b) filament stems having flattened or rounded distal ends unitarily shaped into said second major surface and c) hook elements unitarily shaped into said second major surface; and d) an abrasive coating at least over said raised areas. 6. The abrasive article of claim 5 wherein said abrasive coating comprises abrasive particles and a binder.7. The abrasive article of claim 6 wherein said abrasive coating has a shaped abrasive surface comprising raised areas and depressed areas.8. The abrasive article of claim 5 wherein said pattern on said first major surface is a uniform pattern.9. The abrasive article of claim 5 wherein said pattern on said first major surface is a random pattern.10. The abrasive article of claim 5 wherein shaped engaging elements comprise filament stems having flattened distal ends unitarily shaped into said second major surface.11. The abrasive article of claim 5 wherein said shaped engaging elements comprise hook elements unitarily shaped into said second major surface.12. The abrasive article of claim 5 wherein said abrasive coating comprises a binder make coating into which at least a portion of each abrasive particle is embedded.13. The abrasive article of claim 12 wherein the make coating is a binder selected from the group consisting of acrylate resins, epoxy resins, nitrile rubber resins, urethane resins, aminoplast resins, phenolics resins, urea-formaldehyde resins, polyvinyl chloride resins and butadiene rubber resins.14. The abrasive article of claim 12 further includes a size coating over said make coating and said abrasive particles.15. The abrasive article of claim 14 wherein the size coating is a binder resin selected from the group consisting of phenolic resins, aminoplast resins having pendant α,β-unsaturated carbonyl groups, urethane resins, epoxy resins, ethylenically unsaturated resins, ethylenically unsaturated resins, acrylated isocyanurate resins, urea formaldehyde resins, isocyanurate resins, acrylated urethane resins, acrylated epoxy resins, bis-maleimide resins, fluorine-modified resins, and combinations thereof.16. The abrasive article of claim 5 wherein abrasive particles comprise material selected from the group consisting of fused alumina, silicon carbide, alumina-based ceramics, zirconia, alumina-zirconia, diamond, ceria, cubic boron nitride, garnet, ground glass, quartz, and combinations thereof.
