Abstract
A lenticulated sheet including a polymeric 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. Air is removed from between the backing layer and the lenticular layer second side, and the adhesive layer is adapted to join the backing layer and the lenticular layer second side. The invention also provides processes useful for preparing a lenticular card including an optional core sheet, or optional primer layers.
