A process for manufacturing a pressure sensitive adhesive material permeable to water vapor, characterized in that a continuous coating of an aqueous emulsion based on a sensitive adhesive is formed on a surface which is not very wettable (or not wettable) by water. To the pressure that has dispersed an organic liquid immiscible in water that is more volatile than water and that does not break the emulsion; the coating being left at room temperature until pores develop and reach a size such that the material when dried has a water vapor permeability of 2000 to 10,000 units as defined above; the coating being dried at a higher temperature and the adhesive being transferred to a support or backing material permeable to water vapor.
