【摘要】 介绍了一种新型无明胶重铬酸全息记录材料（简称ＮＧＤ）。ＮＧＤ用特殊的ＴＡＣ作底层，用（ＮＨ４）２Ｃｒ２Ｏ７作光敏物质，具有非常理想的光学性质。因ＮＧＤ的成像机理不同于ＤＣＧ，在潮湿环境中有更显著的抗潮特性，记录的图像也更稳定。讨论了ＮＧＤ光化学反应稳定性的机理、螯合物的微观结构及硬软酸碱定则。更多还原

【Abstract】 A new kind of holographic reCOrding material-Non-Gelatin Dectaomated film(abbreviation NGD)are discovered for the first time.The NGD makes use of a speCial TAC as itS substrate and (NH4)2Cr2O7 as itS Photosensitizer and has very ideal optical property.The cause about steadiness Of NGD hologram on the photochemical reaction and the microstructure of chelahand HSAB principle are discussed.更多还原
