Abstract

"CHAPAS DE IMPRESSãO LITOGRáFICA E PROCESSO PARA SUA PRODUçãO". A presente invenção refere-se à impressão litográfica e, particularmente, a elementos termicamente formadores de imagem de alta resistência a solvente e a métodos de uso bem como a correspondentes chapas de impressão litográficas compreendendo tais elementos termicamente formadores de imagem. Trata-se ainda de processo para produção de chapas e conjuntos para litografia. Conjunto termicamente formador de imagem de trabalho positivo, compreendendo: A - um substrato hidrofílico; B - um elemento formador de imagem, termicamente sensível, de estrutura de camada composta, compreendendo uma primeira camada sobre o substrato e uma segunda camada sobre a primeira camada, a) a primeira camada compreendendo: - um material polimérico que é insolúvel ou substancialmente insolúvel em soluções alcalinas aquosas, que é modificado por composto (s) que torna a composição compreendendo o material polimérico mais solúvel em soluções alcalinas; b) uma segunda camada sobre a primeira camada, a qual é solúvel ou dispersável em soluções alcalinas aquosas, ou solúvel ou dispersável em solução alcalina após aquecimento ou exposição no estado de imagem, em que, quando aquecido ou exposto no estado de imagem, diretamente ou através de absorbância de radiação eletromagnética, as áreas aquecidas ou expostas do conjunto são tornadas significativamente mais solúveis ou dispersáveis em soluções alcalinas aquosas do que as áreas sem imagem.
