发明名称 METHOD AND APPARATUS FOR COATING MICROCAPSULES-CONTAINING COATING AGENT, AND COATED SHEET MANUFACTURED BY THE COATING METHOD
摘要 PROBLEM TO BE SOLVED: To provide a coating method which forms a coating having a reduced defect such as uneven coating or coating streaks on a substrate and having a substantially uniform thickness, using a coating apparatus including a slot die, even if using a highly viscous coating material mixed with a high concentration of microcapsules, and to provide the coating apparatus and a coated sheet manufactured by the coating method. SOLUTION: The coating method includes coating the coating material containing the microcapsules, a binder, and a solvent on the substrate, using the coating apparatus including a slot die, wherein the coating material has a viscosity of 200-2,500 mPa s at a sheer rate of 10s<SP>-1</SP>, and a slot die has a land having a space volume relative to the particle diameter of the microcapsule of 40-450 mm<SP>2</SP>per 1 mm injection width. The coating apparatus includes the slot die used for the coating method. The coated sheet has the coating containing the microcapsules and the binder on the substrate. The coating is formed by the coating method. COPYRIGHT: (C)2011,JPO&INPIT
