PURPOSE:To perform the transfer of a protective film to a working object efficiently and to facilitate the peeling, by forming a sandblast protective printing film with a printing ink made of a resilient sysnthetic resin on the surface of a demold paper then forming a pressure-sensitive adhesive film on said film. CONSTITUTION:A sandblast protective printing film 2 having the thickness of approximately 20-30mu is formed on a demold paper having the surface applied with a wax layer. The printing ink is adjusted by mixing same amount to commercially available PVC resin and phtalic acid plastic agent. A pressure- sensitive adhesive agent 3 is applied through known pressure-sensitive agent to the thickness of approximately 20-30mu onto said film 2, then a peelable protective film paper 4 is jointed to produce a sandblast protective transfer paper (a). After peeling the protective paper 4 and the layer 3 is pressed against an object 6 to be transferred, the sandblast is performed through a nozzle 7. |
