  • the plot is distributed over a wide range of ⁇ a * is ⁇ 20 and ⁇ b * is ⁇ 30, so this experiment is not partial and covers samples with various hue changes. You can see that
  • the effective range is defined by grasping the area as a numerical value.
  • L * and a * of the paper before heating which are not color differences are considered .
  • B * alone was not useful. This is presumably because the color components such as pigments and dyes contained in the colors have different thermal decomposition behaviors, and thus the degree of discoloration after heating differs for each color component. Therefore, the idea of the present invention that can accurately estimate the appearance impression not only with the original paper color but with the degree of color change is reasonable.

Abstract

La présente invention concerne un papier à rouler pour un article à fumer du type à chauffage sans combustion, le papier à rouler ayant une partie colorée dans laquelle un score de détermination, qui est obtenu par une substitution effectuée dans la formule (1) en utilisant des valeurs de différence de couleur dans un système de couleur CIELab entre avant et après que le chauffage du papier à rouler à 230 °C pendant 3 minutes, présente une valeur numérique inférieure à 0,62. Formule (1) : Score de détermination (y) = -0,18×ΔL*+0,08×Δa*+0,13×Δb*-2,36 (dans la formule (1), les valeurs de différence de couleur dans un système de couleur CIELab entre avant et après le chauffage sont des valeurs obtenues par soustraction des valeurs de pré-chauffage L*, a* et b* des valeurs de post-chauffage L*, a* et b*. ΔL* représente la différence de luminosité L* entre avant et après le chauffage du papier à rouler ; Δa* représente la différence de chromaticité a* entre avant et après le chauffage du papier à rouler ; et Δb* représente la différence de chromaticité b* entre avant et après le chauffage du papier à rouler.)
