摘要： PROBLEM TO BE SOLVED: To provide an image recording method which enables the recording of an image by generating an interference color with a clear ink layer.
SOLUTION: An image, which has a specular glossiness of 60 or more and generates an arbitrary interference color resulting from that a light reflected on the surface of a clear ink layer and a light which passes through the clear ink layer and is reflected on the surface of a recording medium generate interference, is recorded by applying a clear ink on the recording medium to form the clear layer which has a thickness of 80-600 nm and does not substantially absorb light in the visible light range to allow the light to pass therethrough.
