Abstract
A method of manufacturing an decoration film includes the steps of forming a semi-finished decoration film formed with a concave-convex pattern on a surface in a method of manufacturing a printing plate including exposure, cleaning, and drying from a photosensitive resin film; and irradiating laser on the concave-convex pattern of the semi-finished decoration film and removing an unnecessary portion to smooth concave-convex parts and/or provide difference in height of a convex part and depth of a concave part of the concave-convex pattern.
Claims7
A method of manufacturing a decoration film comprising the steps of:
- forming a semi-finished decoration film formed with a concave-convex pattern on a surface in a technique of manufacturing a plate including exposure, cleaning, and drying from a photosensitive resin film to a back of which a stretchable resin film is attached,
- a thickness of the photosensitive resin film between adjacent convex parts of the concave-convex pattern is 0;
- and
- irradiating laser on the concave-convex pattern of the semi-finished decoration film and removing an unnecessary portion to smooth concave-convex parts and/or provide difference in height of a convex part and depth of a concave part of the concave-convex pattern.
