Abstract
The present invention provides an imageable composition, which includes an acid curable composition, an acid generator, an infrared absorber, optionally a colorant, such as, a colorant dye or colorant pigment, wherein at least one of the infrared absorber and the colorant has a counter anion derived from a non-volatile acid, and further optionally, a strong acid. The present invention further provides an imageable element, which includes a substrate and an imageable composition according to the present invention coated on a surface of the substrate. Also provided is method of producing an imaged element according to the present invention.

45. A method of producing an imaged element comprising the steps of:
-
providing an imageable element comprising a substrate and an imageable composition coated on a surface of said substrate, said composition comprising an acid curable composition, an acid generator, an infrared absorber and optionally, a colorant, wherein at least one of said infrared absorber and said colorant has a counter anion derived from a non-volatile acid;
imagewise exposing said imageable element to radiation to produce an imagewise exposed element having exposed and unexposed regions;
baking said imagewise exposed element at a temperature and period of time sufficient to produce a cured element; and
contacting said cured element and a developer to remove the unexposed regions and thereby produce said imaged element. - View Dependent Claims (46)
