摘要：
A multi-layer sandwich of vapor deposited metal and release coats in alternating layers is applied to a drum or carrier in a vapor deposition chamber. The metallized layers are applied by vapor deposition. The release layers are solvent soluble thermoplastic or lightly crosslinked polymeric materials applied by vapor deposition in the chamber. The multi-layer sandwich is removed and treated with solvent to dissolve the release coating from the metal flakes. The release coat material can be a radiation curable, crosslinkable vapor deposited polymeric material of low crosslink density. A high energy radiation source crosslinks the release material to produce tack-free, solvent soluble release coat layers. The multi-layer vapor deposit can be built up on an endless belt passing from the chamber through a separate vacuum lock. Both chambers are at vacuum pressures below atmospheric while depositing the flake material. The vapor deposit is removed by reducing belt speed, idling the vacuum deposition sources, and sealing a collection device to the stripping chamber through vacuum locks below the stripping chamber. The stripping chamber is at vacuum pressure below atmospheric when removing the vapor deposit material from the belt.
摘要（中）：
气相沉积金属的多层三明治和交替层的脱模涂层施加到气相沉积室中的鼓或载体上。 通过气相沉积施加金属化层。 释放层是通过气相沉积在室中施加的溶剂可溶性热塑性或轻质交联的聚合物材料。 去除多层三明治并用溶剂处理以从金属薄片溶解脱模涂层。 脱模涂层材料可以是低交联密度的可辐射固化的，可交联的气相沉积聚合材料。 高能辐射源使释放材料交联以产生无粘性溶剂可溶的脱模涂层。 多层蒸气沉积物可以在通过单独的真空锁定从腔室通过的环形带上构建。 两个室在真空压力低于大气压的同时沉积薄片材料。 通过减小皮带速度，空转真空沉积源来除去气相沉积物，并通过抽吸室下方的真空锁将收集装置密封到汽提室。 当从带中去除气相沉积材料时，汽提室的真空压力低于大气压。
