Abstract
An ink jet transparency is provided which exhibits improved wetting properties, thereby resulting in an even surface distribution of ink 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 non-volatile organic acid. Glycolic acid, citric acid, malonic acid, tartaric acid, maleic acid, fumaric acid, malic acid and succinic acid are among the preferred non-volatile organic acids employable in the present invention. The presence of the organic acid results in greatly improved wetting of ink jet ink in solid block areas, preventing the ink from coalescing onto itself. Undesired voids and pin holes in those areas where the ink has been applied are therefore avoided.
