Composition M based on a cellulose ester with formate groups, this composition being an anisotropic solution containing: a) the cellulose ester, b) formic acid, and c) at least one phosphoric acid. The invention also relates to a process for obtaining this composition by dissolving the cellulose. The invention also relates to a process for obtaining articles by the shaping of this composition, with the possibility of regenerating cellulose from these articles. The invention also relates to a cellulose fibre in which the level of substitution of cellulose by formate groups is at least 2%, or zero or less than 2%. Figure 4
