Method for evaluating color tone of coating film and device for this evaluation

摘要

A method giving a color tone-evaluating result which catches the deepness and transparency feelings of a coating film in an objective manner, and a device for use of this method. The evaluating results are obtained by projecting a luminous flux on a coating film, the high light saturation and/or high light excitation purity of the coating film are gotten on a basis of a high light part which is in an angle range of 5 DEG to 15 DEG against the regularly reflecting luminous flux in the reflecting light, and that, if necessary, the shade saturation and/or shade excitation purity are gotten on a basis of a shade part which is in an angle range exceeding 15 DEG .
