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

A device for measuring a coating amount in the case where a microcapsule coating liquid is coated on a microcapsule coating substrate, the microcapsule coating liquid including a microcapsule in which a pigment is encapsulated and dispersed,

• the device comprising:
• a means for irradiating, with illuminating light, the microcapsule coating substrate on which the microcapsule coating liquid is in a wet state;
• a means for detecting an intensity of transmission light which is obtained by illuminating light passing the microcapsule coating liquid in a wet state and the microcapsule coating substrate;
• and
• a means for calculating a thickness of a microcapsule display layer based on the intensity of the transmission light which is detected by the means for detecting the intensity of the transmission light, the microcapsule display layer to be formed by drying the microcapsule coating liquid.

A method for determining a coating-amount wherein a determination is made whether a thickness of a microcapsule display layer is within a predetermined range, the microcapsule display layer being in a dry state after drying a microcapsule coating liquid coated on a microcapsule coating substrate, the microcapsule coating liquid including microcapsule in which a pigment is encapsulated and dispersed, the method comprising steps of:

• finding a correlative relationship between an intensity of transmission light of the microcapsule coating substrate on which the microcapsule coating liquid in a wet state is coated and an actual thickness of the microcapsule display layer formed by drying the microcapsule coating liquid;
• determining an appropriate range of a transmission light intensity of the microcapsule coating substrate on which the microcapsule coating liquid in the wet state is coated, the appropriate range of the transmission light intensity corresponding to a predetermined appropriate range of a thickness of the microcapsule display layer, the appropriate range determined as a standard range from the correlative relationship;
• detecting a transmission light intensity obtained by irradiating the microcapsule coating substrate in a wet state in which the microcapsule coating liquid is coated and is not dried with illuminating light;
• and
• determining the thickness of the microcapsule display layer as being an appropriate value in the case where the transmission light intensity is within the standard range when the transmission light intensity is compared with the standard range, or a non-appropriate value in the case where the transmission light intensity is not within the standard range when the transmission light intensity is compared with the standard range.
