Abstract (en)

[origin: EP3779042A1] Provided is a wrapping paper for a non-combustion heating-type smoking article, the wrapping paper having a colored part in which a discriminant score, which is obtained by through substitution performed in formula (1) by using color difference values in a CIELab color system between before and after the wrapping paper is heated at 230° C for 3 minutes, exhibits a numerical value lower than 0.62. Formula (1): discriminant score (y) = -0.18 × ΔL* + 0.08 × Δa* + 0.13 × Δb* - 2.36 (In formula (1), the color difference values in a CIELab color system between before and after heating are values obtained by subtracting pre-heating L*, a* and b* values from post-heating L*, a* and b* values. ΔL* represents the difference in lightness L* between before and after heating the wrapping paper; Δa* represents the difference in chromaticity a* between before and after heating the wrapping paper; and Δb* represents the difference in chromaticity b* between before and after heating the wrapping paper.)
