A process for producing a cosmetic-impregnated sheet which comprises applying and infiltrating a cosmetic base to and into a base sheet having on the surface thereof a retentive sheet capable of absorbing and retaining the cosmetic base at a shear rate of 10to 10s, the cosmetic base being applied to and infiltrated into the retentive sheet of the base sheet, and the cosmetic base, when subjected to a steady shear deformation at a shear rate of 2 sfor 100 seconds followed by a steady shear deformation at a stepwise increased shear rate of 20 s, showing no shear stress growth or showing such a shear stress growth that the difference between the peak shear stress B at a shear rate of 20 sand the equilibrium shear stress A at the same shear rate, B&#x2212;A, is 20% or smaller of the equilibrium shear stress A in the transition between the two shear rates.

Method of producing cosmetics-impregnated sheet

A coating apparatus 10 is disclosed, which comprises a slot 18 and a chamber 17 formed upstream the slot 18 such as to distribute a coating liquid 12 in a coating width direction. The coating liquid is coated such that it is pressed against a web 11 as it is discharged from the slot. The slot gap H of the slot and the slot gap error .DELTA.H in the coating width direction satisfies a relation

Coating Apparatus

A coating apparatus wherein downstream lips have coating work surfaces respectively where a magnetic dispersoid contacts with a web. A coating work surface of a second downstream lip which is positioned downstream with respect to the web feeding direction is set in a position so as to be apart from the web more than a tangential line which extends from a downstream end of a coating work surface of a first downstream lip which is positioned upstream with respect to the web feeding direction.
