Abstract

A PRESENTE INVENÇÃO DIZ RESPEITO A UM COPOLÍMERO SENSOR E CROMOGÉNICO QUE, POSSUINDO UMA BOA AFINIDADE COM SUBSTRATOS DE CELULOSE, COMPREENDE MONÓMEROS COM PROPRIEDADES CROMOGÉNICAS. UM DELES POSSUI UM GRUPO AMINO AROMÁTICO PRIMÁRIO; O OUTRO MONÓMERO CONTÉM UM ANEL AROMÁTICO ATIVADO. ESTES MONÓMEROS PROPORCIONAM DIFERENTES CORES QUANDO ATIVADOS, DEPENDENDO DA COMBINAÇÃO ENTRE ELES. UM OUTRO ASPECTO DA PRESENTE INVENÇÃO REFERE-SE A PRODUTOS QUE INCORPORAM O COPOLÍMERO CROMOGÉNICO DESCRITO, NOMEADAMENTE UM PRODUTO LÍQUIDO, UMA FIBRA, UMA TINTA, UM REVESTIMENTO PARA MATERIAL PAPELEIRO OU TÊXTIL E UM QUALQUER MATERIAL PAPELEIRO OU TÊXTIL. UM OUTRO ASPECTO DA PRESENTE INVENÇÃO REFERE-SE A UM MÉTODO DE OBTENÇÃO DO POLÍMERO, DE PREPARAÇÃO DE UM MATERIAL PAPELEIRO OU TÊXTIL QUE O INCORPORA, E A UM MÉTODO PARA DETECÇÃO DE CONTRAFAÇÃO E AUTENTICAÇÃO DE PRODUTOS ATRAVÉS DE UM CÓDIGO DE CORES ATINGIDAS POR MEIO DO REFERIDO COPOLÍMERO, PERMITINDO, POR EXEMPLO, A IDENTIFICAÇÃO OU AUTENTICAÇÃO DE DOCUMENTOS, PRODUTOS OU EMBALAGENS, DE FORMA SIMPLES E IMEDIATA.
