Porous film and method for producing the same |
| abstract |
An object of the present invention is to produce a flexible porous film having both high softness and resistance to tearing. A coating solution containing a polymer compound and a solvent is prepared. Apply to support. A coating film is formed on the support. A coating solution is applied so that the solid content K (g / m 2 ) per unit area in the coating film is 0.5 or more and 50.0 or less. After the condensation is formed on the coating film, the coating film is dried. A porous film 10 is obtained. A plurality of holes 11 are formed only on one surface 10 a of the porous film 10. The porous film 10 is made of a thermoplastic polymer compound. The thickness TA of the porous film 10 and the thickness T1 of the porous portion 12 satisfy (1) 0.3 ≦ TA−T1 ≦ 40.0 and (2) 0.5 ≦ T1 / TA ≦ 0.95. [Selection] Figure 2 |
