Abstract
Abstract Transparent image-recording elements that contain ink-receptive layers that can be imaged by the application of liquid ink dots. The ink-receptive layers contain a combination of: (i) a vinyl pyrrolidone; (ii) particles of a polyester, namely a poly(cyclohexylenedimethylene-co-oxydiethylene isophthalate-co-sodio-sulfobenzenedicarboxylate); (iii) a homopolymer or a copolymer of an alkylene oxide containing from 2 to 6 carbon atoms; (iv) a polyvinyl alcohol; (v) a fluorocarbon surfactant of the formula: CF.sub.3 (Ch.sub.2).sub.m CH.sub.2 CH.sub.2 O--CH.sub.2 CH.sub.2 O).sub.n R where m is an integer of 2 through 10, n is an integer of 1 through 18 and R is hydrogen or alkyl of 1 through 10 carbon atoms; (vi) inert particles. A printing method which employs the transparent image-recording elements also is described.
