Embodiment 1

[0090] Example 1 uses Figure 6 The steps shown result in data related to the roughness of the shiny material. refer to figure 1 as well as Figure 6 Then, the measuring section 10 measures the reflectance with respect to a plurality of wavelength components constituting the reflected light reflected from the coating film containing the bright material, respectively (step S1). A plurality of wavelength components are included in a band of 400 nm to 700 nm. The measurement unit 10 executes step S1 with respect to the sample with roughness 2, the sample with roughness 4, the sample with roughness 5, and the sample with roughness 6, respectively.

[0091] The generating unit 55 generates a graph showing the relationship between a plurality of wavelength components and reflectance using the result of step S1 (step S2 ). The generating unit 55 executes Step S2 for each of the samples with roughness 2, the samples with roughness 4, the samples with roughness 5, and the samples wi...

Embodiment 2

[0108] In Example 2, a coating film containing a glossy material formed using a white-based paint was used as an object. White pearls are used as a shiny material. The roughness of the particles of the bright material is represented by 10 stages of roughness 1 to roughness 10 . As the value increases, the shiny material becomes thinner. Therefore, the shiny material is the thinnest in the case of roughness 10.

[0109] As samples of coating films containing bright materials, samples of roughness 1, samples of roughness 2, samples of roughness 4, samples of roughness 5, samples of roughness 6, samples of roughness 8, and samples of roughness A sample of degree 9. The significance of these samples is the same as in Example 1. For example, a sample of roughness 1 is a coating film containing a gloss material formed using a white-based paint containing a gloss material of roughness 1.

[0110] Before describing Example 2, the relationship between the glossiness parameter and ...

Abstract

Among the reflectances of each of the plurality of wavelength components constituting the reflected light in the highlight direction reflected from the coating film containing the bright material, the reflectance at the first wavelength component that becomes the peak and the reflectance with a predetermined wavelength The difference of the reflectance at the second wavelength component is set as a first difference value. The measuring unit measures the reflectance in the first wavelength component and the reflectance in the second wavelength component of the reflected light in the highlight direction of the coating film containing a bright material to be measured. Reflectivity. The first calculation unit calculates the first difference value using the result measured by the measurement unit. The storage unit prestores correlation information indicating a correlation between an index value and the first difference value, wherein the index value represents a predetermined physical characteristic of the bright material included in the coating film containing the bright material. The index value calculation unit calculates the index value of the coating film containing the bright material to be measured using the first difference value calculated by the first calculation unit and the correlation information.

Description

technical field [0001] This invention relates to techniques for evaluating coating films containing brightening materials. Background technique [0002] A coating film containing a glossy material is a coating film formed on an article to be painted by applying a paint (for example, metallic paint, pearl paint) containing a granular glossy material to the article to be painted. By utilizing the fluctuation of light reflected on the surface of the gloss material, the coating film containing the gloss material has different characteristics in appearance (eg, color, texture) according to the viewing direction or the wavelength of illumination light. Describes the technology associated with this feature. [0003] Patent Document 1 and Patent Document 2 disclose techniques for evaluating the texture of metallic paint as techniques for evaluating the texture of a coating film containing a gloss material. [0004] When using a colorimeter to measure the color of a coating film co...
