The influences　of the matrix and pigment of paints on the radiative properties of paint coated surfaces are experimentally made clear. The specimen of paint was prepared by means of mixing matrix and pigment in various ratios and the specimen of coated film was prepared by means of coating paint on a flat aluminum surface. The paint colors were brown，0range and silver.　The total emittance for all specimens and the only spectral emittance for several specimens were measured.　　Consequently，the　following equation of the relation between　mixing　ratio　and normal total emittance was obtained　　　　　　 ε_k = ε_me^<Ak>＋ε_p（1−e＾＜Bk＞） As a whole， the calculated values　agreed well with the measured values except for those in the region of low mixing ratio on the brown and silver paints.
