Donor element for laser-induced thermal transfer

摘要

A laser donor element comprising a transparent support having thereon the following layers in the order recited: a) a hydrophilic layer; b) a propellant layer comprising a gas-producing polymer being capable of forming a gas upon heating by the laser and an infrared-absorbing material, the propellant layer having been coated using a polar solvent having an Et value of between about 0.3 and 1.0; and c) a colorant transfer layer comprising a colorant dispersed in a binder.
