-10 (solid content 60% by weight)) and a solution of 1.2 g of benzoyl peroxide dissolved in 50 cc of toluene to make a uniform adhesive solution of about 20 cI.
The above film having a size of 11 squares was barcoded and dried at room temperature for 20 minutes and then at 80°C for 30 minutes to obtain an adhesive film with a coating thickness of about 30 μm. This was pasted without wrinkles using a rubber roller onto a degreased stainless steel plate 0.5 mm thick, 10 cm wide, and 70% porosity with regular holes of 8 fil+ in outer diameter.

As a result, there was no dimensional change, but the light transmittance of the film alone was as low as 49%, and it was brown, making it difficult to see objects when looking through the film.
〔発明の効果］
本発明によるポリエーテルケトン系フィルムはつぎのよ
うな効果があり加熱調理器の窓材として極めて有用であ
る。[Effects of the Invention] The polyetherketone film according to the present invention has the following effects and is extremely useful as a window material for cooking appliances.
ポリエーテルケトン系フィルムは透明性に優れかつ耐熱
