Abstract (en)

[origin: EP0394460A1] A heat-sensitive recording medium consists of a substrate on at least one surface of which is a dye acceptance layer contg. a cross-linked and cured material derived from (a) a resin having crosslinkable reactive gps.; (b) a crosslinking agent contg. reactive gps. The ratio (molar) of reactive gps. in the crosslinking agent to reactive groups in the resin is pref. 2:1 to 10:1, the crosslinking agent is pref. a cpd. contg. at least two isocyanate gps. A curing catalyst may also be present, such as dibutyltin or dioctyltin. The medium is used for thermal transfer in conjunction with a thermal transfer donor sheet contg. a heat-migratable dye. The surface resistance of the receptor layer is pref. 1 x 10 power (8 or 9) ohm/cm2. An antistatic layer may be applied.
