MANUFACTURING METHOD OF HOLOGRAPHIC MASTER ROLL

摘要

PURPOSE: A method for manufacturing a holographic master roll is provided to a manufacture continuously a holographic film and improve a hardness and a scratch hardness by preventing a crack from a holographic molding plate. CONSTITUTION: A holographic master roll is formed by winding a holographic molding plate on an outer circumference of a metal roll by using a strong bonding agent as much as 360 degrees. The holographic molding plate is formed with a synthetic resin as a kind of an ultraviolet resin including urethane acrylate of 5-90 weight, a polyester acrylate of 5-90 weight, and a monomer of 4-30 weight.
