Abstract

L'invention concerne des couches contenant des colorants blanchissables. Le produit pour l'obtention d'images comprend un support revêtu d'une couche neutre ou acide apte à être blanchie par la chaleur, qui est constituée par un liant, un benzopinacol qui forme des radicaux kétyle, par chauffage au-dessus de 100 degrés C, et un colorant réductible ou un précurseur de colorant réductible qui peut réagir avec les radicaux kétyle. Application à l'obtention de produits thermographiques et de couche filtre ou antihalo pour des produits photographiques et particulièrement photothermographiques.
