Abstract
A lenticulated article including a backing sheet, an imaged transparent sheet having a first smooth side and a second side with a lenticulated region, the transparent sheet optionally having at least one printed image area on the first smooth side and an adhesive layer over the printed image areas and non-image areas of the first smooth side. The second lenticulated side of the transparent sheet has a lenticulated region having a pitch from about 70 to about 100 lenticules per inch, and a ratio of the transparent sheet thickness to the backing sheet thickness is from about 0.25 to about 8.75. The total thickness of the lenticulated article is from about 10 to about 40 mils. The invention also provides processes useful for preparing a lenticular card including an optional core sheet, or optional primer layers.
