PURPOSE: To produce both an air-diffusible self-adhesive sheet which has a very high air diffusibility and is used to reduce the occurrence of whitening. eczema, a rash, etc., on the skin and a dot self-adhesive sheet which has a stable self-adhesive power simultaneously at a low cost without wasting a self-adhesive. ;CONSTITUTION: An air-diffusible self-adhesive sheet 10 is prepd. by applying a self-adhesive 12 to one side of a porous substrate 11 which has a structure of plain weave or network like cheesecloth or lawn and has through-holes 14 coinciding with the structure in such a way that the whole area except the through-holes 14 of the substrate 11 is uniformly coated with the adhesive 12 in a nonflowable state and laminating a release paper 13 to the adhesive layer 12 on the substrate 11. A dot self-adhesive sheet is prepd. by applying a self-adhesive 12 to one side of a dot substrate 21 which comprises an air- diffusible substrate 22 such as a nonwonwoven fabric or gauze or an air- diffusible substrate 23 such as a plastic film in such a way that the adhesive 12 in a nonflowable state is arranged in the same pattern as the through-holes 14 of the porous substrate 11.;COPYRIGHT: (C)1993,JPO&Japio
