Abstract

Abstract An ink jet transparency is provided which exhibits a unique ability to maintain the edge acuity of ink patterns or blocks on the transparency. The ink jet transparency comprises a substantially transparent resinous support, e.g., a polyester film, and a substantially clear coating thereon which includes a specific fluorosurfactant. The presence of the fluorosurfactant of the present invention in the clear coating prevents trailing of the ink-jet ink. As a result, patterns and ink blocks do not trail into one another on the transparency, but maintain their defined shape and size.
