Abstract

"CORANTES E LâMINAS MAGNéTICAS, RESISTENTES MULTICAMADAS". São fornecidas camadas de pigmento magnético em múltiplas camadas e lâminas; as lascas de pigmento podem ter uma estrutura de camadas empilhadas sobre lados opostos de um núcleo magnético, ou podem estar formadas como uma estrutura encapsulante com camadas encapsulantes em volta do núcleo magnético; o núcleo magnético na estrutura de camadas empilhadas inclui uma camada magnética que está imprensada entre camadas isolantes opostas, que por sua vez estão comprimidas entre camadas refletoras opostas; da mesma maneira, o núcleo magnético dentro da estrutura encapsulante inclui uma camada magnética que está envolvida por uma camada isolante que, por usa vez está envolvida por uma camada refletora; as camadas isolantes nas lascas de pigmento evitam substancialmente a corrosão das lascas quando expostas a ambientes íngremes; algumas configurações das lascas de pigmento e das lâminas apresentam uma ligeira mudança de cor em diferentes ângulos de incidência de luz ou de visualização; as lascas de pigmento podem ser dispersas dentro de um meio líquido como tinta para ambientes ou tinta para canetas para produzir composições colorantes para a subseq³ente aplicação em objetos ou papeis; as lâminas podem ser aplicadas sobre vários objetos ou podem ser formadas sobre uma base transportadora.
