  • the method for suppressing the occurrence of color difference by re-coating of the present invention comprises: When applying as a coating film forming material, uniform color tone (chromaticity, hue) by suppressing the color difference (color difference between the undercoated surface and the overcoated surface) caused by seaming and repair. (Color) can be effectively used for forming a colored stucco coating film. That is, the method of the present invention can be effectively used for providing a water-containing colored stucco composition that can be repaired or overcoated.
  • the method for suppressing color jump of a colored stucco coating film of the present invention is intended to suppress the whitening of a colored stucco coating film to form a coating film having a desired color. Can be effectively used to suppress the occurrence of color difference due to the difference in color, and to suppress the occurrence of color unevenness due to the time-dependent color jump of the colored stucco coating film. That is, the method for suppressing color jump of a colored stucco coating film of the present invention is useful for forming a colored stucco blocking film having a uniform tint (chromaticity, hue, and color).

Abstract

La présente invention concerne un procédé permettant de colorer une composition de plâtre, permettant, d'une part de colorer de façon uniforme la totalité d'une composition de plâtre, et d'autre part de former des couches de plâtre coloré attrayantes. L'invention concerne également un emballage dans lequel la couleur de la composition de plâtre frais coloré peut être maintenue de façon stable pendant le stockage de façon à permettre une utilisation immédiate pour l'application de plâtre coloré sur le chantier. A cet effet, on colore une composition de plâtre comprenant de la chaux, un liant et de l'eau, utilisant comme pigment une combinaison faite d'un pigment colorant et d'un pigment blanc. On peut les utiliser avec succès pour éviter les différences de teintes des couches de plâtre coloré résultant du recouvrement de compositions de plâtre coloré frais, pour éviter les irrégularités des couches de plâtre coloré après prise et séchage, et pour éviter la dispersion des couleurs d'une couche de plâtre coloré.
