Abstract
A printing system consisting of at least two reactive components is disclosed, in which one component is a polymer having attached at least one functional group that is reactive with an aziridine, such as a carboxyl, thiocarboxyl, sulfonic, phosphoric, epoxy, or isocyanate group or derivative thereof, and the other component is an aziridine, which printing system can be used to provide printed images of excellent quality that are wet-rub resistant and accent marker resistant. In addition to using the invention two-component system to produce printed images directly, a method for using the two-component system to develop lithographic printing plates is disclosed.
Claims36
An ink jet printing process comprising sequentially applying to a substrate a first liquid composition comprising an aziridine and second liquid composition comprising a polymer having a functional group reactive with the aziridine, said polymer being characterized by a weight average molecular weight of about 1,000 to 20,000.
