Abstract

L'invention se rapporte à la formation d'images. Elle concerne un procédé pour former des images colorées d'une haute opacite, caractérisé en ce qu'il comprend les étapes consistant à : a. Amener en contact deux couches 1 et 2, la couche 1 étant une couche photosensible supportée ayant des zones d'image poisseuses et non-poisseuses et contenant au moins un plastifiant, la couche 2 étant une couche pigmentée supportée de manière adhésive, la couche pigmentée comprenant de 75 à 95 parties de pigment et de 25 à 5 parties d'un liant élastomère, le liant, quand il est coulé sous la forme d'une pellicule non-supportée, ayant une résistance maximale à la traction de moins de 14 kg/cm**2 et présentant un allongement à la rupture d'au moins 5 % : et b. Séparer la couche 2 de la couche 1 de manière que la couche pigmentée reste adhérente seulement sur les zones d'image poisseuses de la couche 1. Utilisation notamment pour la production d'enseignes, d'affichettes, etcThe invention relates to the formation of images. It relates to a method for forming colored images of high opacity, characterized in that it comprises the steps of: a. Contacting two layers 1 and 2, layer 1 being a supported photosensitive layer having tacky and non-tacky image areas and containing at least one plasticizer, layer 2 being an adhesively supported pigmented layer, the pigmented layer comprising 75 to 95 parts of pigment and 25 to 5 parts of an elastomeric binder, the binder, when cast as an unsupported film, having a maximum tensile strength of less than 14 kg / cm ** 2 and exhibiting an elongation at break of at least 5%: and b. Separate layer 2 from layer 1 so that the pigmented layer remains adherent only to the sticky image areas of layer 1. Use in particular for the production of signs, posters, etc.
