Abstract
A laser-induced melt transfer process is described in which a melt viscosity modifier is used to facilitate the melt transfer process.
Claims3
A laser-induced melt transfer method for making a color image which consists essentially of:
- a) imagewise exposing to laser radiation a laserable assemblage comprising
- 1) a donor element consisting essentially of a support bearing on a first surface thereof a composition selected from the group consisting of:
- (A)(i) at least one colorant and (ii) at least one melt viscosity modifier to lower melt viscosity,
- (B)(i) at least one colorant, (ii) at least one melt viscosity modifier to lower melt viscosity, and (iii) a binder,
- (C)(i) at least one colorant, (ii) at least one melt viscosity modifier to lower melt viscosity, and (iv) a laser radiation absorbing component, and
- (D)(i)at least one colorant, (ii) at least one melt viscosity modifier to lower melt viscosity, (iii) a binder and (iv) a laser radiation absorbing component,
- wherein (i) and (ii) can be in the same or different layers, and
- 2) a receiver element situated proximally to the first surface of the donor element, wherein a substantial portion of (i) and (ii) is transferred to the receiver element;
- b) separating the donor element from the receiver element,
- steps (a)-(b) being repeated at least once using the same receptor and a different donor element having a colorant the same as or different from the first colorant.
