The color change in samples of unpigmented self-curing resins prepared with a new initiator using barbituric acid derivatives (Ba-CI-Cu) was found to be less than specimens prepared with conventional Benzoylperoxide-tert Amine initiator (BPO-tert Amine). One cause of the perceivable color change for BPOtert Amine was the increase in the values of |Δa*| and |Δb*| during storage periods. ANOVA showed statistical significance in that the higher the storage temperatureand the longer the periods of sunlight exposure, the higher the value of ΔE*ab for BP0-tert Amine became. On the other hand, in the case of pigmented resins, the values of ΔE*ab for ivory shade (Ba-Cl-Cu/I) except 60°C-dry and for pink shade (Ba-Cl-Cu/P) were less than 1 during storage for 56 days. Therefore, no color differences could be perceive either before or after storage and exposure to the various conditions. In the case of 37°C-wet, i.e., oral environment, the values of ΔE*ab for Ba-Cl-Cu/I and Ba-Cl-Cu/P were approximately 1/6 to 1/2 and 1/15 to 1/4, respectively, compared with the values of a commercially available product.
