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 a vinyl pyrrolidone polymer with a polyester, a poly(cyclohexanedimethylene isophthalate-co-sodiosulfobenzenedicarboxylate), dispersed in the vinyl pyrrolidone to control ink dot size. A printing method which employs the transparent image-recording elements is described.
