Definitions

  • the polymeric microspheres comprise a non-adhesive type polymer such as polymethyl methacrylate, an adhesion force Is low, and the film may be spontaneously peeled off when it is used outdoors. Since the viscoelastic layer absorbs the unevenness on the surface when the adhesive film is adhered to the adherent, it should have a flowability such that it can be easily deformed by pressing. However, this Utility Model application does not describe any degree of the viscoelasticity of the layer.
  • any conventionally used additive may be used as long as the effects of the present invention are not impaired.
  • the additives are a crosslinking agent, a viscosity modifier, an anti-foaming agent, a leveling agent, a UV light absorber, an antioxidant, a pigment, etc.
  • Elastic microspheres means a material at least a surface of which has tackiness, and exhibits rubbery elasticity as a whole.
  • the rubbery elasticity of the microspheres is necessary for the formation of passageways which prevent disappearance of bubble escaping passages due to the plastic deformation of the microspheres caused by the pressure.
  • the microspheres themselves make it easy and sure to form the cluster structure, and improve the adhesion force of the adhesive layer to the uneven surface.
  • the volume average diameter of the microspheres is usually from 10 to 300 ⁇ m, preferably from 30 to 200 ⁇ m.
  • Cluster of elastic microspheres means the agglomerate of the elastic microspheres which are dispersed in a bulk form of two or more of the microspheres in the matrix of the tacky polymer to form a convex part (convex adhesive part) having an irregular shape and irregular configuration. That is, the adhesive layer comprises "island” parts (discrete phases) comprising the cluster(s) and the tacky polymer, and relatively flat “sea” parts (continuous parts) comprising the tacky polymer but no cluster.
  • the adhesive film having such clusters is schematically shown in Fig. l .
  • the adhesive film 1 has the discrete adhesive parts 3 containing the clusters of the microspheres 2.
  • a silicone liner (P 530 BH manufactured by TOKUSHU SEISHI) was laminated, and then the polyester carrier was removed from the substrate film to obtain an adhesive film

Abstract

On décrit un film adhésif, lequel est capable à la fois de faire s'échapper les bulles d'air lors du processus d'adhésion, et de présenter une résistance à l'arrachage permanente et élevée ainsi qu'une bonne apparence de surface de film après adhésion. Ce film adhésif comprend un film substrat, une couche de primaire formée sur ce film ainsi qu'une couche supérieure, laquelle est formée sur la couche de primaire et contient des microsphères élastiques ainsi qu'un premier adhésif polymère, ce film étant caractérisé en ce que la couche de primaire comprend un second polymère adhésif et présente un module d'élasticité en compression compris entre 1 x 106 et 1 x 10?7 dyn/cm2¿, et en ce que les microsphères élastiques comprennent un troisième polymère adhésif et présentent un diamètre moyen volumique de l'ordre de 10 à 300 νm.
