HOLOGRAM FILM

摘要

PURPOSE: A hologram film is provided to form a hologram despite a laminating temperature and heat when a card is manufactured, thereby reinforcing durability against heat and pressure of a hologram. CONSTITUTION: A hologram film includes a heat-resistant layer in a film. The hologram film includes a releasing layer(20), a deposition layer(50), and an adhesive layer(70). The hologram film includes a primer layer(30). The heat-resistant layers are formed immediately on the deposition layer, the adhesive layer, or a primer layer respectively. A hologram concavo-convex is formed on the heat-resistant layer. A hologram concavo-convex is formed on the primer layer. The heat-resistant layer is made of a thermosetting resin selected from a phenol resin, an urea resin, melanin resin, a polyester resin, an epoxy resin, an urethane resin or a silicon resin.
