  • silicone adhesive coating 1 To 100 parts by mass of a silicone compound (manufactured by Shin-Etsu Chemical Co., Ltd., trade name KR-3704), 0.5 parts by mass of a platinum catalyst for curing (manufactured by Shin-Etsu Chemical Co., Ltd., trade name, CAT-PL-50T) was added. Then, the mixture was thoroughly mixed and diluted with a solvent toluene so that the solid content was 40% by mass to obtain a silicone pressure-sensitive adhesive coating material 1.
  • a silicone compound manufactured by Shin-Etsu Chemical Co., Ltd., trade name KR-3704
  • platinum catalyst for curing manufactured by Shin-Etsu Chemical Co., Ltd., trade name, CAT-PL-50T
  • acrylic adhesive paint 1 1.5 parts by mass of a curing agent (manufactured by DIC, trade name D-100K) is added to 100 parts by mass of a main agent (manufactured by DIC, trade name Fine Tack CT-3088), and they are sufficiently mixed to obtain an acrylic adhesive. Agent coating material 1 was obtained.
  • Examples A to C On one surface of each of the films of Examples 7, 8 and 9, the above primer coating was applied so that the dry coating film had a thickness of 3 ⁇ m, and dried at 100 ° C. for 2 minutes with a hot air circulation dryer. Further, ultraviolet rays were radiated by an ultraviolet curing device so that the integrated light amount would be 200 mJ / cm 2 to obtain primer-treated films 7 ′, 8 ′, 9 ′ each having a primer layer formed on the surface of the base material. It was Then, the urethane pressure sensitive adhesive paint 1 is applied on the primer layer side surface of the primer-treated film 7'so that the thickness of the dried coating film is 50 ⁇ m, and the hot air circulation dryer is used for 1 minute at 120 ° C. It dried and formed the adhesive layer. Thus, the transparent screen film with the adhesive layer of Example A was obtained.
  • Example A In the same manner as in Example A, except that the primer-treated film 7 ′ was changed to the primer-treated film 8 ′ and the urethane pressure-sensitive adhesive coating 1 was changed to the silicone pressure-sensitive adhesive coating 1 in the above-mentioned Example A. A transparent screen film with an adhesive layer was obtained.
  • Example A In the same manner as in Example A except that the primer-treated film 7 ′ was changed to the primer-treated film 9 ′ and the urethane adhesive paint 1 was changed to the acrylic adhesive paint 1 in the above-mentioned Example A, A transparent screen film with an adhesive layer was obtained.
  • the obtained transparent screen films with an adhesive layer of Examples A to C were cut out into A4 size and attached to a glass plate, and it was confirmed that they all showed good attachability without peeling or bubbles. .. In addition, no significant difference was observed in the image and color of the projection screen image before and after applying the adhesive layer.
