PURPOSE:To improve pollution resistance, weatherability and stability by a method wherein heat-transferable protective layer containing solvent-soluble fluorine-containing resin or its hardened matter and hot melt resin is separably provided on a tissue-like base. CONSTITUTION:Onto tissue-like base 3, weatherproof layer 2 and hot melt resin-containing bonding layer 1 are laminatingly formed from the base 3 side as independent layers so as to form heat transferable protective layer out of both the layers 1 and 2. The weatherproof layer 2 contains solvent-soluble fluorine-containing resin such as polytetrafluoroethylene or the like. Further, the weatherproof layer 2 may contain thermosetting or thermoplastic resin. The preferable thickness of the layer 2 is set to be about 2-50mum. The bonding layer 1 may well contain the same additive as that to the weatherproof layer 2 in addition to the hot melt resin. |
