发明名称 HYDROPHILIC POROUS FILM AND MULTI-LAYERED FILM COMPRISING THE SAME
摘要 <p>A film-like material of the present invention comprises a multi-layered film comprising a hydrophilic porous film containing a thermoplastic resin as a main component and having a colored part on one face thereof and, provided on the other face thereof, a layer for preventing permeation of water. Furthermore, the hydrophilic porous film is obtained by forming a thermoplastic resin composition into a film, and then stretching the film in at least a uniaxial direction, wherein the thermoplastic resin composition comprises 25 to 80 parts by mass of a thermoplastic resin and 75 to 20 parts by mass of a filler and further a hydrophilicity imparting agent in an amount of 0.1 to 10 parts by mass relative to 100 parts by mass, where the total amount of the thermoplastic resin and the filler is 100 parts by mass.</p>
