Lenticular print three dimensional image display device and method of fabricating the same

摘要

The invention provides a lenticular lens type three-dimensional image display device and a method of fabricating the device without a need for a clear plastic substrate transposed between the image and lenticular lenses. The device can be obtained by directly printing curable coatings onto the image, making them particularly well suited for volume production. The combination the image printing and application of curable coatings process can be joined together to conduct the single pass-process. The single pass-process allows for flexibility of the printing only selective areas of the substrate. Moreover, this process allows the device to be recyclable.

主权项

1. A lenticular print three dimensional image display device comprising:
(A) a substrate with a proximate surface and a distal surface wherein an interlaced image is printed on either surface of the substrate; (B) a first curable coating composition that comprises (i) at least one acrylate monomer, (ii) an acrylate oligomer with a backbone that comprises one or more groups selected from epoxy, polyester, urethane, acrylic and silicone, (iii) a photoinitiator, and (iv) a surface tension lowering additive; and wherein the first curable coating composition is applied on the proximate surface of the substrate in a first pre-determined pattern on the proximate surface of the substrate; and (C) a second curable coating composition that comprises (i) at least one acrylate monomer, (ii) an acrylate oligomer with a backbone that comprises one or more groups selected from epoxy, polyester, urethane, acrylic and silicone, and (iii) a photoinitiator; wherein the second curable coating composition is applied on the proximate surface of the substrate, and wherein the second curable coating composition self-registers into a second pattern that does not overlap with the first pre-determined pattern; and wherein the liquid surface tension of the second curable coating composition is at least 2 dynes/cm2, as measured by ASTM D1084, higher than the surface tension of the cured first curable coating composition, as measured by ASTM D7490-08.
