Therefore, even if also can obtain bounding force for contact area is little, consider following mode etc., that is, the bounding force by improving bonding coat or make the bonding coat softness, thus the concave-convex surface of lining body is absorbed in the bonding coat, make contact area become big, obtain bounding force thus.
For the raising of the self adhesion of realizing bonding coat, can in being applicable to the styrene series elastomer of tackiness agent, add tackifying resin (for example with reference to patent documentation 1 etc.)。But when the bonding coat that excessive interpolation tackifying resin in styrene series elastomer is constituted utilized the forcing machine coextrusion and is laminated in substrate layer, the melt viscosity that produces bonding coat reduced, be difficult to substrate layer extend, problem such as consuming time.In addition, carrying out with feed piece (feed block) method when stacked, after bonding coat is extended in substrate layer, also can make the melt viscosity of bonding coat be lower than substrate layer, therefore, bonding coat is slowly wrapped up in bag in the end of film width, and the end only is made of bonding coat, also can cause the film end to adhere to faults such as film-making machine thus.
In addition, by in styrene series elastomer, adding tackifier, go up required self-adhesion and make a concerted effort (for example with reference to patent documentation 2 etc. thereby can embody to use to prismatic lens.), still, if just add tackifier in styrene series elastomer, extractable may not be good when then extracting film out after making film become the roller state.
