We present a curated and openly accessible dataset of optical and thermal radiative properties of solid materials, digitized from the TPRC Data Series edited by Y. S. Touloukian et al. The dataset comprises 1251 curves describing emittance, reflectance, transmittance, and absorptance of solid materials, covering broad temperature and spectral ranges. Each data record includes detailed metadata and is fully traceable to the original publication cited by the TPRC volumes. The digitization workflow, data structure, and quality controls were designed to support the FAIR principles, enabling reproducible reuse of radiative property data in thermophysics and materials research. The dataset has been used to feed an open database of optical and thermal radiative properties: EKHI. Its website (thermomat.ehu.eus/ekhi) provides interactive querying and visualization of the dataset. This dataset expands the availability of machine-readable radiative property data for solids and offers a foundational resource for modeling, data-driven analysis, and materials informatics.
