Abstract
An element for use in a laser induced ablative transfer process, said element comprising a support bearing on a first surface thereof at least one coating comprising (i) a non-sublimable imageable component, (ii) a laser radiation absorbing component, (iii) a particular filler having an average particle size (S), and (iv) optionally a binder, wherein the non-sublimable imageable component and the laser radiation absorbing component can be the same or different; wherein the total thickness of all coatings present on the first surface is T and further wherein S.gtoreq.2T is described.

An element for use in a laser-induced ablative transfer process, said element comprising:
- (a) a support, bearing on a first surface thereof
- (b) at least one transfer coating comprising:
- (i) a non-sublimable imageable component,
- (ii) a laser-radiation absorbing component,
- (iii) a particulate filler having an average particle size S, and
- wherein the non-sublimable imageable component and the laser-radiation absorbing component can be the same or different;
- wherein the coatings on the first surface of the support have a total thickness T;
- and further wherein S.gtoreq.2T.
A laser-induced ablative transfer process which comprises:
- (1) imagewise exposing to laser radiation a laserable assemblage comprising:
- (A) a donor element comprising
- (a) a support bearing on a first surface thereof,
- (b) at least one transfer coating comprising:
- (i) a non-sublimable imageable component,
- (ii) a laser-radiation absorbing component,
- (iii) a particulate filler having an average particle size S, and
- wherein the non-sublimable imageable component and the laser-radiation absorbing component can be the same or different;
- wherein the coatings on the first surface of the support have a total thickness T;
- and further wherein S.gtoreq.2T;
- and
- (B) a receiver element situated proximally to the first surface of the donor element, wherein a substantial portion of the imageable component (i) is transferred to the receiver element by ablative transfer;
- and
- (2) separating the donor element from the receiver element.
