Abstract

ARTIGO RETRORREFLEXIVO COM VARIAçãO DE COR E MéTODO PARA PRODUZIR UM ARTIGO RETRORREFLEXIVO COM VARIAçãO DE COR Artigos retrorreflexivos com variação de cor podem prover características tais efeitos decorativos, evidência adulteração, autenticação de segurança ou informação de posição. Em algumas modalidades, o artigo retrorreflexivo com variação de cor compreende uma camada de microesfera (14), e um revestimento reflexivo que está disposto em associação óptica com a camada de microesferas. O revestimento reflexivo inclui uma camada espaçadora (24) disposta entre uma primeira camada reflexiva semitransparente (22) e uma segunda camada reflexiva (26) . A primeira camada reflexiva unclui uma camada reflxiva disposta adjacente à camada de microesferas (tl, t2). Pelo menos uma camada do revestimento reflexivo inclui um espessura não uniformes associada com cada uma de uma pluraridade de de microesferas de tal modo que a luz incidente sobre o artigo a partir de uma primeira direção é retrorreflexitida a um primeira cor e a luz incidente sobre o artigo a partir de uma segunda direção é retrorrefletida a uma segunda cor visivelmente diferente da primeira cor.
