Abstract (en)
[origin: WO9506692A1] A self-adhesive film having no tackiness, which can repeatedly be used, and show no cohesive failure even if crosslinked films are adhered to each other and then debonded, and which can be prepared from a simple material is provided. A film composed of a copolymer of the monomer of an acrylic acid ester and the oligomer of a (meth)acrylic acid ester having a mutually reactive functional group in a molecule. The Tg value of a homopolymer obtained by homopolymerization of the aforesaid acrylic acid ester monomer is higher than 20 DEG C (Tg > 20 DEG C). The Tg value of a homopolymer of the (meth)acrylic acid ester forming the aforesaid oligomer is lower than -20 DEG C (Tg < -20 DEG C), and the F value defined by the following equation is within the range between 2.8 x 10<-3> and 3.7 x 10<-3>. F = W1/(Tg1 + 273.2) + W2/(Tg2 + 273.2) + ... Wn/(Tgn + 273.2). W1 to Wn denote, respectively, the weight fraction of the first to n-th components, consisting of the monomer and the oligomer, and Tg1 to Tgn denote, respectively, the Tg values ( DEG C) of the first to n-th components, consisting of the homopolymer of the (meth)acrylic acid ester monomer and the oligomer.
