Abstract
A resin-molded product includes a phenol-based oxidation inhibitor, and a thiol-based compound. The thiol-based compound reacts chemically with a coloring substance (or a compound having a quinone-type structure) resulting from the phenol-based oxidation inhibitor to interrupt a long conjugated system arising in the coloring substance. As a result, the absorption due to the coloring substance is canceled in the visible light region. Thus, the resin-molded product is inhibited from yellowing.
