Abstract
The invention provides a method of making a material, said method comprising generating a foamed hydrophilic polymer solution, especially of a gelatin or derivative thereof, and treating said foamed hydrophilic polymer solution with sufficient energy and for a sufficiently short time that a polymer foam having an open-cell structure is formed. The invention also provides a material comprising a support and an ink receiving layer supported on the support, the ink receiving layer comprising porous hydrophilic polymer, especially gelatin, and is formed by coating a solution of foamed hydrophilic polymer, especially gelatin, onto a support substrate and drying the coated substrate for a time period selected to be short enough such that an open-cell foam is formed.
