<p>A transfer printing medium comprises a heat resistant substrate (2, 102, 202) and a photo- and thermo-sensitive film (10, 11, 110, 111, 210) disposed on the substrate. The film comprises porous micro-capsules (3, 103, 203) containing colouring material (4, 104, 204), and being responsive to thermal energy to release the colouring material, a photo-sensitive resin (6, 106, 206) arranged to undergo photo-polymerisation in response to exposure to light to control the rate of transfer of the released colouring material, and an initiator (7, 107, 207) effective to initiate the photo-polymerisation. The micro-capsules, the resin and the initiator are distributed in a binder (5, 105, 205) for support.</p> |
