30. An imageable element comprising:
-
a substrate; and
an imageable coating on a surface of the substrate, the coating comprising;
an acid curable composition;
an acid generator; and
a colorant, wherein the colorant includes a counter anion derived from a non-volatile acid, and wherein the colorant enhances the visual contrast between image areas and non-image areas after imaging of the imageable element;
and further comprising an infrared absorber, a photothermal converter material, or both. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)

50. A method of making an imageable element including a substrate and an imageable coating on the substrate, the method comprising the steps of:
-
contacting a substrate with an imageable composition dissolved or dispersed in a suitable solvent, wherein the imageable composition comprises an acid curable composition, an acid generator, and a colorant, wherein the colorant includes a counter anion derived from a non-volatile acid, and wherein the colorant enhances the visual contrast between image areas and non-image areas after imaging of the imageable element;
and further comprises an infrared absorber, a photothermal converter material, or both; and
drying to remove solvent, leaving an imageable coating on the substrate.

51. A method of producing an imaged element comprising the steps of:
-
providing a thermally imageable element comprising a substrate and a thermally imageable coating on a surface of the substrate, the coating comprising an acid curable composition, an acid generator, and a colorant, wherein the colorant includes a counter anion derived from a non-volatile acid, and further comprising an infrared absorber or a photothermal converter material;
imagewise exposing the imageable element to heat to produce an exposed element having exposed and unexposed regions of the coating;
baking the exposed element at a temperature and period of time sufficient to produce a cured element; and
contacting the cured element with a developer to remove the unexposed regions of the coating and thereby produce the imaged element;
wherein the colorant enhances the visual contrast between image areas and non-image areas of the imaged element. - View Dependent Claims (52)
