Alkyd resins and reactive diluents, which are among the main components of dye films; It has properties such as binding, superior performance, easy application and versatile usage. Various modification studies are carried out in order to improve the film properties of resins and reactive diluents used in dye formulations. In this study, the reactive diluent was synthesized as a result of Diels – Alder reactions with safflower oil and dienophil type 2,2,2-Trifluoroethyl Methacrylate (TFEM). Four different dye formulations were obtained by mixing the synthesized reactive diluent, soybean oil-based alkyd resin, wetting and drying agents at different ratios (10, 20, 30 and 40%). Prepared dye samples were applied on 8 cm x 10 cm aluminum plates with an applicator. After the application, the dye film samples were left to dry completely at room temperature for 7 days after curing at 120 °C for 2 hours and then at 160 °C for 3 hours. Glass transition temperatures (Tg) of dye film samples with reactive diluent SOA, SOTFEM10-SOA, SOTFEM20-SOA, SOTFEM-SOA and SOTFEM40-SOA were determined by Differential Scanning Calorimetry (DSC) method and glass transition temperatures determined in Dynamic Mechanical Analysis method (DMA) (Tg). Tg values in dye film samples were determined close to each other in DSC and DMA methods. As the reagent diluent composition increased, the Tg values decreased in itself.
