摘要

PROBLEM TO BE SOLVED: To provide a paint color evaluation panel capable of more accurately evaluating a paint color including highlight and/or shade by considering a case regarding a paint color which looks different in accordance with an observation angle.;SOLUTION: A paint color evaluation panel 10 comprises a paint applied surface 7 on at least one side. The paint color evaluation panel further comprises: a principal surface 1 which is a convex curved surface surrounded by straight or curved line sides 1a, 1b, 1c, 1d and 1e; corner R parts 4 and 5 curved along boundary lines 6 and 8 when defining one side of the principal surface 1 as the boundary lines 6 and 8; and sub surfaces 2 and 3 which are convex curved surfaces neighboring to the principal surface 1 with the corner R parts 4 and 5 interposed therebetween. The principal surface 1 and the sub surfaces 2 and 3 are convex curved surfaces having different curvatures with the corner R parts 4 and 5 interposed therebetween, in cross sections vertical to the boundary lines 6 and 8, and the curvatures are varied along length directions of the boundary lines 6 and 8.;COPYRIGHT: (C)2015,JPO&INPIT
