A blackhead-removing face pack sheet with superior ease of use and blackhead-removing capacity is provided. The blackhead-removing face pack sheet 1 is formed from a laminate which comprises a gas-permeable and flexible base layer 2 and a pack material layer 3 the primary component of which is a copolymer of vinyl acetate and N-vinyl-2-pyrrolidone. The base layer 2 comprises a porous material such as a nonwoven fabric, and part of it is impregnated or embedded with the pack material constituting the pack material layer 3. This gives a high force of adhesion between the base layer 2 and the pack material layer 3.

L'invention concerne une feuille de garniture servant à enlever un bouchon kératosique, qui présente une excellente maniabilité et d'excellentes propriétés d'élimination de bouchon kératosique. La feuille (1) de garniture servant à enlever un bouchon kératosique est un laminé se composant d'une couche (2) de base flexible perméable à l'air, et d'une couche (3) de garniture contenant un copolymère d'acétate de vinyle / N-vinyl-2-pyrrolidone comme constituant principal. La couche (2) de base est constituée d'une matière poreuse tel qu'un non-tissé partiellement imprégné d'une substance de garniture constituant la couche (3) de garniture, ou dans laquelle la substance de garniture est partiellement incorporée. On obtient ainsi une force d'adhérence élevée entre la couche (2) de base et la couche (3) de garniture.
