Abstract

Согласно изобретению предлагается магнитный ОВП (оптически варьируемый пигмент), причём упомянутый пигмент состоит из тонкослойных хлопьев, имеющих базовую структуру типа металл-диэлектрик-металл, благодаря которой обеспечивается изменение видимого цвета пигмента в зависимости от угла зрения, и обладает, помимо указанной способности к изменению своего видимого цвета в зависимости от угла зрения, также и соответствующими магнитными свойствами, что позволяет отличить этот пигмент от ОВП, имеющего аналогичный внешний вид, но не обладающего упомянутыми магнитными свойствами. Согласно изобретению предлагаются также способы получения таких пигментов, а также раскрываются возможности применения таких пигментов в качестве обеспечивающих защиту элементов путём введения их в состав различных печатных красок, покрытий и занесения их на различные предметы и изделия.
