Process for waterproofing leather (1), which comprises pressing on the internal surface of the leather (1) at least one semi-permeable membrane (2) whose surface contacting the leather (1) is provided with a glue pattern. The glue pattern of the semi-permeable membrane (2) is preferably thermoadhesive, and therefore the pressing of said membrane on the leather (1) is preferably a hot pressing. Further, said semi-permeable membrane (2) is preferably elastic, non-porous and combined with a support sheet (3). The present invention relates also to the leather obtained by means of said process.
