Abstract

"TINTA DE SEGURANçA FLEXOGRáFICA COM FLUORóFOROS PRóXIMOS AO INFRAVERMELHO". As tintas flexográficas que contêm colorantes e compostos fluorescentes próximos ao infravermelho proporcionam documentos impressos com impressão colorida, incluindo preto e segurança NIRF. Os sistemas de impressão de uma combinação de tintas flexográficas propiciam que qualquer cor seja impressa com segurança NIRF. Os processos de impressão propiciam pigmentos com absorção alta no infravermelho, a serem usados em tintas para impressão em formato de tela.
