A hook strip is provided having a backing with a first surface and a length in a first direction; multiple rows of hook elements aligned in the first direction and projecting from the first surface of the backing; and slits in the backing between at least some pairs of adjacent rows of the hook elements. The slits may be interrupted by a bridging region of the backing, or the slits may be partial slits that penetrate the thickness of the backing in a range from 40 to 90 percent. A fastening laminate that includes a carrier and the hook strip described above joined to the carrier is also provided. In some embodiments, the fastening laminate includes slits that form separate, abutting portions of the backing on the carrier. An absorbent article containing the hook strip and a method of making the hook strip are also disclosed.

1. A hook strip comprising: a backing having a first surface and a length in a first direction and first and second side edges;multiple rows of hook elements aligned in the first direction and projecting from the first surface of the backing; andinterrupted slits cut through the backing between at least three pairs of adjacent rows of the hook elements, wherein each of the interrupted slits extends in the first direction and is interrupted by at least one intact bridging region of the backing;wherein the number of rows of the hook elements between at least some of the interrupted slits increases from the second side edge to the first side edge. 2. The hook strip of claim 1, wherein the backing is not joined to a carrier. 3. The hook strip of claim 1, wherein a distance between interrupted slits is smaller at the second side edge than at the first side edge. 4. The hook strip of claim 1, wherein for any two adjacent interrupted slits, the bridging regions are staggered in a cross direction perpendicular to the first direction. 5. A fastening laminate comprising a carrier and the hook strip of claim 1, wherein the backing has a second surface opposite the first surface, and wherein the second surface of the backing is joined to a portion of the carrier. 6. An absorbent article having at least a front waist region, a rear waist region, and a longitudinal center line bisecting the front waist region and the rear waist region, wherein at least one of the front waist region or the rear waist region comprises the fastening laminate of claim 5, wherein the fastening laminate has a proximal end attached to the absorbent article and a distal end where peel is initiated, and wherein the second side edge of the backing is closer than the first side edge to the distal end of the fastening laminate; and wherein the first direction of the hook strip is aligned with the longitudinal center line. 7. A hook strip comprising: a backing having a first surface and a length in a first direction;multiple rows of hook elements aligned in the first direction and projecting from the first surface of the backing;an interrupted slit cut through the backing between at least one pair of adjacent rows of the hook elements, wherein the interrupted slit extends in the first direction and is interrupted by at least one intact bridging region of the backing; anda partial-depth cut in the first surface of the backing in the at least one intact bridging region, wherein the partial-depth cut is collinear with the interrupted slit but does not extend through the backing. 8. The hook strip of claim 7, wherein the backing is not joined to a carrier. 9. The hook strip of claim 7, wherein there are interrupted slits cut through the backing between at least three pairs of adjacent rows of the hook elements, and wherein the number of rows of hook elements between at least some of the interrupted slits varies. 10. A fastening laminate comprising a carrier and the hook strip of claim 7, wherein the backing has a second surface opposite the first surface, and wherein the second surface of the backing is joined to a portion of the carrier. 11. A hook strip comprising: a backing having a first surface, a thickness, a length in a first direction, and no slits through the backing;multiple rows of hook elements aligned in the first direction and projecting from the first surface of the backing; anda partial slit cut into the first surface of the backing between at least one pair of adjacent rows of the hook elements, wherein the partial slit extends in the first direction and penetrates the thickness of the backing in a range from 40 to 90 percent. 12. The hook strip of claim 11, wherein the hook elements have loop-engaging overhangs, and wherein at least a portion of each loop-engaging overhang extends at a nonzero angle to the partial slit. 13. The hook strip of claim 11, wherein the partial slit is interrupted by at least one bridging region of the backing that is not slit. 14. The hook strip of claim 11, wherein there are partial slits cut through the backing between at least three pairs of adjacent rows of the hook elements, and the number of rows of hook elements between at least some of the partial slits varies. 15. A fastening laminate comprising: a carrier;a backing having a first surface, a second surface opposite the first surface, a thickness, a length in a first direction, first and second side edges, a top edge and a bottom edge, wherein the second surface of the backing is joined to a portion of the carrier;multiple rows of hook elements aligned in the first direction and projecting from the first surface of the backing; andslits cut into the backing between at least three pairs of adjacent rows of the hook elements, wherein each of the slits extends in the first direction and forms abutting portions of the backing on either side of the slit, and wherein the number of rows of hook elements between at least some of the slits increases from the second side edge to the first side edge;wherein at least the portion of carrier to which the second face of the backing is joined has up to a ten percent elongation in a second direction perpendicular to the first direction. 16. The fastening laminate according to claim 15, wherein each of the slits is cut through the thickness of the backing and extends from the top edge to the bottom edge of the backing to form separate, abutting strips of the backing on the carrier. 17. The fastening laminate according to claim 15, wherein each of the slits is a partial slit cut into the first face of the backing that penetrates only partially through the thickness of the backing. 18. The fastening laminate according to claim 15, wherein each of the slits is an interrupted slit that is cut through the backing and interrupted by a bridging region of the backing, wherein the bridging region of the backing is collinear with the interrupted slit but is not cut or penetrates only a portion of the thickness of the backing. 19. An absorbent article having at least a front waist region, a rear waist region, and a longitudinal center line bisecting the front waist region and the rear waist region, wherein at least one of the front waist region or the rear waist region comprises the fastening laminate of claim 18, wherein the fastening laminate has a proximal end attached to the absorbent article and a distal end where peel is initiated, and wherein the second side edge of the backing is closer than the first side edge to the distal end of the fastening laminate; and wherein the first direction of the hook strip is aligned with the longitudinal center line.
