PURPOSE:To obtain a shutter blade for a camera which is lightweight and flexible and has a sufficient running speed, by packing a reinforcing material in a plastic material and by forming an organic film which has lubricity and the properties of preventing reflection and cutting off light. CONSTITUTION:A plastic material, such as epoxy resin, charged with a reinforcing material, such as glass cloth, is formed thermally into a film or sheet. Its surface is coated with organic paint to which a lubricity providing agent and carbon black having the properties of preventing reflection and cutting off light are dispersed and added, thus forming a multicolor lubricant organic film. This material is used to manufacture a shutter blade for a camera. Consequently, the shutter blade is flexible and less deformed, and has an enough running speed by limited driving force. Further, it is effective to use this shutter blade for, specially, an electromagnetically driven shutter. |
