INK COMPOSITION FOR PROJECTION PATTERN PRINTING, INTERIOR SHEET, INTERIOR PRODUCT AND PROJECTION PATTERN PRINTING METHOD

摘要

PURPOSE: A method for printing a projection pattern is provided to obtain an excellent outer shape by forming the projection pattern on a substrate using a composition for printing the projection pattern and to be used for a mass production due to superior productivity. CONSTITUTION: A method for printing a projection pattern comprises the following steps: printing the projection pattern having a thickness of 0.2-2.0 mm on a substrate using a composition including photocurable acrylate oligomer, reactive diluents, a first photoinitiator with an absorption edge wavelength of 250-350 nm, and a second photoinitiator with an absorption edge wavelength of 400 nm or greater; pre-drying the projection pattern at 10-90°C for 1-9 minutes; and hardening the dried projection pattern by irradiating ultraviolet ray to the projection pattern.
