The present invention relates to a method for preparing a material, intended for example for the formation or publication of images, said material enabling the drying time to be reduced by facilitating water evaporation and absorption of the compositions applied to said material. The material according to the invention comprises a support and at least one hydrophilic binder-based layer, and is characterized in that, in at least one of said hydrophilic binder-based layers, said hydrophilic binder comprises heat-sensitive pairs at LCST, said heat-sensitive parts having been selected so that their LCST is lower than the temperature at which the material was dried. The material according to the invention can be used as photographic material or as receiving material for aqueous ink compositions applied by the ink jet printing technique.
A method for preparing a material comprising a support and at least one hydrophilic binder-based layer, said method comprising the following steps:
A material comprising a support and at least one hydrophilic binder-based layer, characterized in that, in at least one of said hydrophilic binder-based layers, said hydrophilic binder includes heat-sensitive parts, said heat-sensitive parts being water-soluble at temperatures below their lower critical solution temperature (LCST) and hydrophobic above their LCST, said heat-sensitive parts having been selected so that their LCST is less than the temperature at which the material was dried.
