Abstract (en)
[origin: EP3832013A1] Provided is rolling paper for a non-combusted heated smoking article that has a white section in which the discrimination score obtained by substituting color difference values in the CIE Lab color system before and after heating for three minutes at 230°C in equation (1) is a numerical value lower than 0.62 and ISO whiteness is at least 83%. (1) Discrimination score (y) y = -0.18 × ΔL* + 0.08 × Δa* + 0.13 × Δb* - 2.36 (In equation (1), the color difference values in the CIE Lab color system before and after heating are the values for L*, a*, and b* before heating subtracted from the values for L*, a*, and b* after heating. ΔL* represents the difference in lightness L* after heating and before heating the rolling paper. Δa* represents the difference in color a* after heating and before heating the rolling paper. Δb* represents the difference in color b* after heating and before heating the rolling paper.)
