摘　　要：采用5层全介质膜系结构,高低折射率膜层交替堆叠,高折射率层材料选择二氧化钛,低折射率层选择二氧化硅,制得设计主波长为665 nm,随角异色效果为紫红色至黄绿色的高波段半透型光干涉防伪颜料。用Shimadzu UV-3600i Plus紫外可见近红外分光光度计检测样品位于薄膜,膜粉,颜料三状态的透射光谱和反射光谱,对颜料片混合光固化油墨后所制成油墨的实际应用效果进行了刮样测试。结果表明,所制备颜料在保留鲜艳颜色且随角异色效果明显的前提下,能清晰地显示底板上的文字或图案,涂敷该颜料能在保留标志防伪设计效果的前提下,为标志提供随角异色防伪效果,提高标志防伪能力。A high-wave semi-transparent optical interference pigment with a main wavelength of 665nm and a col-or effect of purplish red to yellowish green was prepared by using 5 layers of full dielectric film system with alternating stacking of high and low refractive index films,titanium dioxide for high refractive index layer and silicon dioxide for low refractive index layer.The transmission spectrum and reflection spectrum of the sample in the three states of film,film powder and pigment were detected by the UV-3600i Plus UV-visible near-infrared spectrophotometer of Shimad-zu.The practical application effect of the ink made by mixing the pigment sheet with light curing ink was tested by scraping sample.The results show that the prepared pigment can clearly display the text or pattern on the bottom plate under the premise of retaining bright colors and obvious anti-counterfeiting effect with the corner.The coating of the pigment can provide anti-counterfeiting effect with the corner and improve the anti-counterfeiting ability of the logo under the premise of retaining the anti-counterfeiting design effect of the logo.
