Abstract
An object of the present invention is to provide a flaky metal pigment that is reduced in particle size. According to the flaky metal pigment of the present invention, in the case where the flaky metal pigment is measured by a flow-type particle image analyzer, P50 showing a 50% cumulative frequency of a diameter equivalent to an area circle in a number distribution is less than 0.500 μm.
Claims8
A flaky metal pigment,
- said flaky metal pigment being made of aluminum, and
- in a case where said flaky metal pigment is measured by a flow-type particle image analyzer, P50 showing a 50% cumulative frequency of a diameter equivalent to an area circle in a number distribution being less than 0.500 μm,
- in the case where said flaky metal pigment is measured by the flow-type particle image analyzer, Pmax showing a maximum particle diameter of a diameter equivalent to an area circle in the number distribution being 5.000 μm or less,
- Pmax/P10 being 1 or more and 18 or less, wherein P10 is a value of a 10% cumulative frequency in the number distribution of the flaky metal pigments measured by the flow-type particle image analyzer.
