More Information
Summary:Disclosed is a lenticular sheet obtained by the method comprising the steps of: forming lenticular lens section on the input side of the sheet; forming an irregular section having a plurality of depressions and protrusions on the output side of the sheet; forming a light-absorbing layer on each protrusion; and filling each depression with a light-transmittable resin. The lenticular sheet provides a tolerance needed for fine pitch pattern processing and can be manufactured by using a conventional printing process as it is, thereby providing excellent contrast characteristics as well as excellent moldability. La présente invention concerne une feuille lenticulaire s'obtenant par un procédé consistant à former une zone lenticulaires sur la face d'entrée de la feuille, à former un dépoli en creux et relief sur la face sortie de la feuille, à former une couche photo-absorbante sur chaque relief, et à combler chaque creux avec une résine photoémissive. Cette feuille lenticulaire, qui respecte des tolérances convenant au traitement de tracés fins, peut se fabriquer par impression conventionnelle, ce qui lui confère de bonnes qualités de contraste et une très bonne aptitude ou moulage.
