PURPOSE: To obtain a tonable photosensitive compsn. by constituting the compsn. of specific compds., photoinitiator and specific polycaprolactones, thereby satisfying the requirement conditions of adhesive equil. with respect to a cover film and a base. CONSTITUTION: The tonable photosensitive compsn. contg. at least one compds. reacting with active rays so as to induce a change in the tacky adhesiveness of the compsn., the photoinitiator or the photoinitiation system, and in some cases, a polymer binder or binder mixture, and at least one polycaprolactones having an average mol.wt. of at least 50000 affecting the adhesive characteristic of the compsn. is formed. Such tonable photosensitive compsn. may be applied by a known method on the preferably transparent and suitable base and dried. A suitable example of the base is synthetic resin films of polyethylene, polypropylene, polyamide and polyester. |
