Title: MATERIAL INTENDED FOR FORMING OR PRINTING IMAGES AND ITS MANUFACTURING METHOD
Abstract:
The present invention relates to a material intended for forming or printing images, comprising a support and at least one hydrophilic binder-based layer, and its manufacturing method, said method enabling the gelation process of the hydrophilic binder to be controlled. The material according to the invention is characterized in that in at least one of said hydrophilic binder-based layers, said hydrophilic binder is gelated by complexation with a complexing agent present on a heat-sensitive polymer or copolymer, that is hydrophobic at temperatures higher than its lower critical solution temperature LCST to protect the complexing agent, and water-soluble at temperatures less than its LCST to make the complexing agent accessible, the LCST of the heat-sensitive (co)polymer being higher than the setting temperature of said hydrophilic binder. The material according to the invention can be used as photographic material or as material taking aqueous ink compositions applied by the inkjet printing technique.
