Wrappers for smoking articles are disclosed having reduced ignition proclivity characteristics. The wrappers include discrete areas treated with a reduced ignition composition. In accordance with the present disclosure, the amount of burn promoting agents is controlled over the surface of the wrapper in order to, in one embodiment, increase the permeability of the treated areas.

1. A wrapper for a smoking article comprising: a paper substrate comprising cellulose fibers and a filler, the paper substrate having a width and a length;a plurality of discrete reduced ignition areas extending in the width direction on the paper substrate and being spaced along the length direction;at least one burn accelerating area positioned in between a first reduced ignition area and a second adjacent reduced ignition area, the burn accelerating area comprising a burn promoting agent; andwherein the reduced ignition areas are free of the burn promoting agent and wherein the reduced ignition areas have a permeability of greater than 25 Coresta while having a diffusivity of less than about 0.5 cm/s at 23° C. 2. A wrapper as described in claim 1, further comprising: at least one untreated area, the untreated area being located between a first edge of the burn accelerating area and the reduced ignition area; andwherein the untreated area and the reduced ignition areas are free of the burn promoting agent. 3. A wrapper as defined in claim 1, wherein the reduced ignition areas are formed from a non-fibrous film-forming composition. 4. A wrapper as defined in claim 1, wherein the reduced ignition areas comprise a starch composition. 5. A wrapper as defined in claim 1, wherein the reduced ignition areas comprise an alginate composition. 6. A wrapper as defined in claim 1, wherein the plurality of discrete reduced ignition areas comprise circumferential bands having a width of from about 3 mm to about 10 mm. 7. A wrapper as defined in claim 2, wherein the wrapper includes first and second untreated areas, the first untreated area being located between the first edge of the burn accelerating area and the first reduced ignition area, the second untreated area being located between a second edge of the burn accelerating area and a second reduced ignition area. 8. A wrapper as defined in claim 7, wherein the first and second untreated areas comprise circumferential bands having a width of from about 0.1 mm to about 4 mm. 9. A wrapper as defined in claim 1, wherein the reduced ignition areas comprise areas where a reduced ignition composition has been applied to the paper substrate in an untreated state. 10. A wrapper as defined in claim 1, wherein the reduced ignition areas have a diffusivity at 23° C. of from about 0.15 cm/s to about 0.5cm/s. 11. A smoking article comprising: a column comprising a smokable tobacco; anda paper wrapper surrounding the column of the smokable tobacco, the paper wrapper comprising the wrapper of claim 1. 12. A smoking article as defined in claim 11, wherein the smoking article has a pass rating according to ASTM Test E2187-09 of at least 75%. 13. A smoking article as defined in claim 11, wherein the column comprising the smokable tobacco has a density of from about 200 mg/ml to about 250 mg/ml. 14. A wrapper for a smoking article comprising: a paper substrate comprising cellulose fibers and a filler, the paper substrate having a width and a length;a plurality of discrete reduced ignition areas extending in the width direction on the paper substrate and being spaced along the length direction, the reduced ignition areas being formed from a film-forming composition that is free from fibrous cellulose materials and free from particle cellulose materials:at least one burn accelerating area positioned in between a first reduced ignition area and a second adjacent reduced ignition area, the burn accelerating area comprising a burn promoting agent; and wherein the reduced ignition areas are free of the burn promoting agent. 15. A wrapper as defined in claim 14, wherein the reduced ignition areas have a permeability of greater than 20 Coresta. 16. A wrapper as defined in claim 15, wherein, when the wrapper is incorporated into a smoking article having a tobacco density of from 200 mg/mi to 250 mg/ml and tested according to ASTM Test E2187-09, at least 75% of the smoking articles self extinguish. 17. A wrapper as described in claim 14, further comprising: at least one untreated area, the untreated area being located between a first edge of the burn accelerating area and the reduced ignition area; andwherein the untreated area and the reduced ignition areas are free of the burn promoting agent. 18. A wrapper as defined in claim 17, wherein the wrapper includes first and second untreated areas, the first untreated area being located between the first edge of the burn accelerating area and the first reduced ignition area, the second untreated area being located between a second edge of the burn accelerating area and a second reduced ignition area. 19. A wrapper as defined in claim 18, wherein the first and second untreated areas comprise circumferential bands having a width of from about 0.1 mm to about 4 mm. 20. A wrapper as defined in claim 14, wherein the reduced ignition areas are formed from a non-fibrous film-forming composition. 21. A wrapper as defined in claim 14, wherein the reduced ignition areas comprise a starch composition or an alginate composition. 22. A wrapper as defined in claim 14, wherein the plurality of discrete reduced ignition areas comprise circumferential bands having a width of from about 3 mm to about 10 mm. 23. A wrapper as defined in claim 14, wherein the reduced ignition areas have a diffusivity at 23° C. of from about 0.15 cm/s to about 0.5 cm/s. 24. A smoking article comprising: a column comprising a smokable tobacco; anda paper wrapper surrounding the column of the smokable tobacco, the paper wrapper comprising the wrapper of claim 14. 25. A smoking article as defined in claim 14, wherein the smoking article has a pass rating according to ASTM Test E2187-09 of at least 75%.
