Title:
ROLLING PAPER FOR NON-COMBUSTION HEATING-TYPE SMOKING ARTICLE, NON-COMBUSTION HEATING-TYPE SMOKING ARTICLE, AND ELECTRIC HEATING-TYPE SMOKING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/229850
Kind Code:
A1
Abstract:
Provided is a rolling paper for a non-combustion heating-type smoking article, the rolling paper having a colored part in which a determination 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 rolling paper is heated at 230°C for 3 minutes, exhibits a numerical value lower than 0.62. Formula (1): Determination 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 luminosity L* between before and after heating the rolling paper; Δa* represents the difference in chromaticity a* between before and after heating the rolling paper; and Δb* represents the difference in chromaticity b* between before and after heating the rolling paper.)
