The invention describes a sheet product comprising a paper sheet having on its front a printable coating comprising a pigment and a binder, and on its back isolated droplets of colour former solution each confined within a pressure rupturable barrier, in which the paper sheet carrying said pigment/binder coating has a Bendtsen porosity in excess of 100 ml/min prior to the application of the droplets of colour former solution.
