Abstract
A laser-imageable assembly comprising a transparent substrate having on a surface thereof an energy absorbent transfer layer comprising particles which absorb laser energy dispersed in a heterogeneous resin layer. Heterogeneity may be achieved by appropriately drying the coated substrate. The assembly may also comprise one or more additional layers of primer, protective and lubricant coatings. A preferred assembly comprises a polyester substrate with a graphite-containing heterogeneous transfer layer.
