The invention relates to a paper that disintegrates quickly in water, for use as a filter material or filter wrapper paper of a cigarette filter. At least 80 wt % of the paper is formed by cellulose fibers. Of the cellulose fibers, at least 80 wt % are a mixture of long fiber pulp and mercerized pulp. 0 to 90 wt % of the content of the mixture is formed by mercerized pulp, and the rest is formed by long fiber pulp. The cellulose fibers of the mixture have a freeness of at most 30° SR according to ISO 5267. In the disintegration test using an apparatus as described in TAPPI T 261, the paper exhibits a disintegration of at least 60% after 30 seconds.
