An image is formed on a transfer medium comprising a hydrophilic tackifier. Any portion of the image that is dimensionally insufficient to permanently adhere the image to the receiver substrate is determined, and a colorless liquid ink comprising water is applied to cover and surround the portion of the image that is dimensionally insufficient to permanently adhere the image to the receiver substrate. When heat is applied to the image to transfer the image layer to a receiver substrate, water in the image layer swells the image layer and the hydrophilic tackifier becomes sufficiently tacky to permanently adhere the image to the receiver substrate.

A thermal transfer recording medium includes a base, a release layer disposed on or above the base, and a thermally fusible ink layer disposed on or above the release layer. The release layer includes wax and ethylene-propylene-ethylidene norbornene rubber.

Provided is a thermosensitive recording medium having a sufficient water resistance to moisture and humidity, such as for outdoor use in rainy weather and the like, and also having a superior color developing sensitivity, print image quality when printing at high speed, ink fixability and solvent resistance and the like. As the protective layer comprises a specific silane-modified acrylic resin which is an aqueous emulsion of core-shell type p articles, in a thermosensitive recording medium having a thermosensitive recording layer on a substrate and a protective layer on the thermosensitive recording layer, the thermosensitive re cording medium has a sufficient water resistance and also has a superior color developing sensitivity, print image quality when printing at high speed, ink fixability and solvent resistance and the like.
