<p>PURPOSE:To obtain the title film having both properties of an adhesion to a protective film and a suitable peeling from a base layer by using a plastic film having a specific critical surface tension to the base film layer and the protective film layer respectively. CONSTITUTION:The plastic film having <35dynes/cm the critical surface tension is used to the base film layer, and the plastic film having >=35dynes/cm the critical surface tension is used to the protective film in the masking film 1 laminated a colorless transparent base film layer 4, a sticking agent layer 3 having a shading property and the protective film layer 2 in order. The sticking agent layer having the shading property provided on the protective film layer comprises a sticking composition such as an acrylic resin or a gum and also, a thermoplastic resin having a compatibility and capable of mixing with said sticking composition and having the sticking property may be used. The acrylic sticking composition having the excellent weather ability and sticking property is more preferable.</p> |
