In this study, the Restoration color of three manufacturers (Companies A, B, and C) used for retouching are selected, and the differences in paint properties based on the resin type used by each manufacturer as the medium are compared. The results indicate that the paint produced by each manufacturer differs in terms of the ingredients, color development characteristics, durability, and reversibility. The paint by Company A (binder: mastic resin) shows the best reversibility; however, it exhibits significant discoloration and numerous cracks after deterioration, as well as chalking in some colors. The paint by Company B (binder: acrylic resin) is superior to those of other manufacturers in terms of discoloration and cracking, although its reversibility is unsatisfactory. The paint by Company C (binder: aldehyde resin) shows significant discoloration, and small holes are observed on the sample surface after deterioration. The results are consistent with the deterioration characteristics of the resin used as the medium; additionally, the restoration color differs in terms of durability and reversibility depending on the resin used as the medium. It is expected that the above results can be used not only as essential reference data when selecting materials for retouching, but also to predict problems that may appear in the restoration part of the work using Restoration color and to come up with management measures.
