Abstract

L'invention décrit un article, en forme de craie de classe, pour écrire, dessiner et colorier en obtenant des images fixables à chaud. L'article comprend un liant (résine de synthèse fusible et/ou thermodurcissable), au moins un pigment colorant (minéral ou organique) et éventuellement des solvants solubles dans la matière de synthèse et des additifs usuels. Le pigment constitue de 5 à 50 % du poids total (liant + pigment). L'article permet de dessiner sur n'importe quel support et d'obtenir, par un chauffage modéré (jusqu'à 200 degrés C environ) une fixation donnant une image stable.The invention describes an article, in the form of classroom chalk, for writing, drawing and coloring by obtaining heat-fixable images. The article comprises a binder (fusible and / or thermosetting synthetic resin), at least one coloring pigment (inorganic or organic) and optionally solvents soluble in the synthetic material and customary additives. The pigment constitutes from 5 to 50% of the total weight (binder + pigment). The article makes it possible to draw on any support and to obtain, by moderate heating (up to approximately 200 degrees C), a fixation giving a stable image.
