目的の為に多くの試みがなされている。(Prior art) Conventionally, medical adhesive products such as bandages are applied directly to the human body, but if left in that state for a long time, moisture evaporation from the skin surface is blocked, causing itching. A rash occurs. This can be prevented by providing breathability to the adhesive product. Therefore, many attempts have been made for this purpose.

気孔の形成は比較的出来難いという問題があった。(Problem to be Solved by the Invention) The above method has a method in which the adhesive layer coated on the releasable sheet contains
A discontinuous water-dispersed coating is formed, and the water prevents the adhesive from adhering during the subsequent drying process, which removes the organic solvent and forms the final adhesive layer. This method takes advantage of the phenomenon in which small pores are formed in areas where water is present after evaporation. There is a problem that the water dispersed in the organic solvent solution of the adhesive is squeezed out by a roll, and the material containing the necessary water is not coated.Also, even if a method that does not cause such dehydration is adopted, the solvent and water are squeezed out. Because water is relatively microscopically dispersed,
When coating and drying, there is no difference in evaporation time between the two, and as the solvent evaporates, water tends to evaporate at the same time, making it relatively difficult to form vent holes.

クロンを越えると水滴が粘着剤層内にめり込まず、通気
孔を形成することが出来ない。In the present invention, the reason why water droplets are sprinkled on the surface of the adhesive layer while it is in an undried state is that when the adhesive layer is subsequently dried, the areas where the water droplets were present open up and become vent holes. Because it will be. The particle size of the water droplets sprayed at this time is 10
It must be within the range of ~1000 microns, and if it is less than 10 microns, it will be difficult to form vent holes, and even if some are formed, the pore diameter will be too small and the breathable base material will be used in the subsequent process = 6 If stacked on top of each other, it will be crushed. Furthermore, if the thickness exceeds 1000 microns, water droplets will not sink into the adhesive layer, making it impossible to form ventilation holes.

If the amount is exceeded, time and energy will be consumed to dry the sprayed water, and processing costs will increase.

表面に水滴を散布する方法としては、スプレ一方式が好
適であるが、特にその手段は問わない。In the present invention, as a method for spraying water droplets on the surface of the adhesive layer while it is in an undried state, a spray method is suitable, but the method is not particularly limited.
水滴を散布後乾燥して水滴及び有機溶媒を揮散すること
により、粘着剤層に多数の通気孔が形成される。By spraying water droplets and drying to volatilize the water droplets and organic solvent, a large number of vent holes are formed in the adhesive layer.

優れたものを工業的規模で製造し得る。(The following is a blank space) = 12- Table (Effect) The present invention provides a method for forming ventilation holes in an adhesive layer by applying a solvent solution of an adhesive applied to a removable sheet in an undried state. By adopting a method of spraying water droplets when the adhesive is in the adhesive layer, the water droplets sink into the adhesive layer, creating uneven areas in the adhesive layer, and after drying, air holes are reliably formed in the areas where water was present. do. By laminating this breathable adhesive layer on a breathable base material, a breathable adhesive tape or sheet can be obtained. The solvent does not evaporate together with the evaporation of the existing solvent, and the formation of vents using water droplets is easy and reliable, and products of excellent quality can be manufactured on an industrial scale.
