Patent ID: 8062827

Claim:
A positive-working, multi-layer, infrared radiation-sensitive imageable element comprising a substrate having thereon: an inner layer comprising an infrared radiation absorbing compound and a first polymeric binder composition that is present in an amount of from about 65 to about 97 weight %, and an ink receptive outer layer comprising a second polymeric binder that is different than said first polymeric binder, and is soluble or dispersible in an alkaline developer only after exposure to imaging radiation, said first polymeric binder composition comprising either: a) one or more polymeric binders each independently being represented by the following Structure (I): -(A) x -(B) y —(C) z — (I) wherein A represents recurring units comprising pendant oxazoline groups, B represents recurring units comprising functional groups that are crosslinkable with said pendant oxazoline groups, C represents recurring units other than those defined by A and B, x is from about 5 to about 50 weight %, y is from about 5 to about 50 weight %, and z is from about 2 to about 90 weight %, b) one or more polymeric binders each independently being represented by the following Structure (II): -(A) m -(C) n — (II) and one or more polymeric binder each independently being represented by the following Structure (III): —(B) p —(C) n — (III) wherein A, B, and C are as defined above, and m, n, and p are independently from about 1 to about 99 weight %, wherein the weight ratio of the polymeric binder represented by Structure (II) to the polymeric binder represented by Structure (III) is from about 5:1 to about 1:5, c) one or more of each of the polymeric binders represented by Structures I, II, and III, d) one or more of each of the polymeric binders represented by Structures I and II, or e) one or more of each of the polymeric binders represented by Structures I and III.
