Method and device for measuring coating amount, method and device for determining coating amount, coating device and method for manufacturing coating product

摘要

One embodiment of the present invention is a method for measuring a coating amount in the case where a microcapsule coating liquid including a microcapsule in which a pigment is encapsulated and dispersed is coated on a microcapsule coating substrate, the method including steps of: detecting a transmission light intensity in the case where the microcapsule coating substrate on which the microcapsule coating liquid is in a wet state is irradiated with illuminating light; and calculating a thickness of a microcapsule display layer from the transmission light intensity, the microcapsule display layer formed by drying the microcapsule coating liquid.
