Abstract
The invention is generally accomplished by forming a translucent display material comprising a substrate and sensitized layers wherein said substrate comprises a paper that has a light transmission rate of greater than 17 percent. It is preferred that the paper have a basis weight of less than 120 grams per square meter that is resin-coated on both sides. The paper of the invention when exposed and developed has a difference between maximum density and minimum density of greater than 2.5. The sensitized layers prior to imaging comprise at least one layer comprising cyan dye-forming coupler, at least one layer comprising magenta dye-forming coupler, and at least one layer comprising yellow dye-forming coupler. In preferred forms, the paper has a basis weight of between 70 and 100 grams per square meter for a balance of translucence and strength. The couplers preferably are present in the following amounts: cyan coupler greater than 0.6 grams per square meter, magenta coupler greater than 0.6 grams per square meter, and yellow coupler in an amount greater than 0.6 grams per square meter.
