Method for color matching of glittering material-containing coating film and structural member with glittering agent-containing coating

摘要

PROBLEM TO BE SOLVED: To provide a technology which can easily match colors of two parts which are applied with a coating in different atmospheres.SOLUTION: When matching, for example, an L-value (L2) of a resin part to an L-value (L1) of a steel plate part by changing and adjusting colors out of both the two parts of the steel plate part and the resin part which are applied with the same color coating at preset initial coating conditions, a combination and an adjustment amount of a suitable parameter out of coating parameters such as the spray pressure of a spray gun at a coating process of the resin part, a gun distance, a discharge amount, discharge pressure, and a flash time are selected and set, the parts 2 are applied with a coating at a set and color-corrected coating condition, the L-value of the resin part is rotated as L2', and a difference between the L-value of the steel plate part and that of the resin part is constantly adjusted. Furthermore, by increasing and decreasing a pigment or a bright material by a prescribed amount, the L-value of the resin part is adjusted so as to match the L-value of the steel plate part.
