Stereo photo material coating, substrate-free stereo photo material and its manufacture method

Abstract

The invention is an admixture composed of ink-absorbent acrylamide or polyvinyl alcohol, calcium carbonate, ethoxyl cellulose, urea, low molecule alcohols, methacrylate, silica and water. Said low molecule alcohols are ethanol or isopropyl alcohol. The manufacturing method thereof comprises: using coater or varnishing machine to paint said coating materials on stereo imaging grating material to form a layer in 0.01-0.03mm thickness; the grating material coated with the coating materials moves on the varnishing machine in a speed of 35-45 m / min; drying the material at 50-60 deg. C to get the stereo photo material without substrate.

Description

Technical field: The invention relates to a material for making three-dimensional photos and a manufacturing method thereof, in particular to a paint for a three-dimensional photo material, a substrate-free three-dimensional photo material and a manufacturing method thereof. Background technique: For a long time, 3D image production has always used lenticular 3D plastic sheets + double-sided tape + photo paper images to make 3D photos, which is inefficient. Since the stripes of the lenticular material need to be aligned with the multi-images on the photo paper image, the alignment must be done under double-sided adhesive two-way bonding, which is difficult to manufacture and requires the operator to be careful, patient, and two people to cooperate to complete the process. . Generally, it takes several hours to make a three-dimensional photo, especially for large format, which requires professional alignment equipment and is difficult to control. Difficulties and technologi...

Patent No.: 96236597.1 Utility Model Patent "Coated Lenticular Sheet for Stereo Photos" and Patent No.: 96237454.7 Utility Model Patent "Gap Coated Lenticular Sheet" respectively disclose a coated grating that directly forms a stereoscopic photo after exposure film, but the two grating films are composed of a grating and a substrate coated with a photosensitive material on the bottom surface, and both need to bond the grating film with a thick transparent substrate and a transparent adhesive, so the thickness is still relatively large. Large, the phase effect is not good enough

Moreover, this kind of material is generally only suitable for studios to enlarge photos, not for printing three-dimensional photos.
