Abstract

구성재료인 기포의 직목에 기인하는 섬유표면의 얼룩이 없고, 롤상으로 권취되며, 필요시에는 권출하여 사용할 수 있으며, 감김, 신장, 느슨함 등의 변형이 곤란하여 취급하기에 용이한 반사형 영사시이트이다.
탄성한도 60kg/㎠ 이상, 영률 2.5×104kg/㎠ 이상, 굴곡탄성율 3.5×104kg/㎠ 이하, 두께 35∼200㎛, 중심선평균 거칠기와 물결상을 가짐과 동시에 100㎛ 이하의 치수안정성 기재시이트의 표면에 농밀도 광확산반사층, 연질 염화비닐수지 시이트로 된 반투명광확산층을 순서대로 적층하고, 상기 반투명광확산층의 표면에는 미소한 요철 모양을 형성시킨 것이다.
또한, 필요에 따라서는, 치수안정성 기재시이트에 백색 또는 암색안료를 첨가하고, 경우에 따라서는, 상기 시이트에 농밀도 광확산반사층의 반대면에 백색불투명 수지층 또는 암색불투명 수지층을 순서대로 적층할 수 있다.
