Abstract

La présente invention est relative à un matériau à deux composants pour diazocopie, pouvant être développé par la chaleur, caractérisé en ce qu'il comprend un support portant au recto un revêtement sensible à la lumière contenant un composé diazonium et un agent de copulation et qui, contient, comme agent de développement thermique, a) un sel d'ammonium ayant un point de fusion d'au moins 115 degrés C, b) un sel d'un métal alcalin ou d'un métal alcalin-terreux ou un oxyde ou hydroxyde de métal alcalino-terreux, et c) un sel d'amine d'un acide présentant une constante de dissociation d'au moins 10**-3 et capable de fondre par chauffage à une température comprise entre 70 et 100 degrés C, le constituant b de l'agent de développement étant présent dans une couche produite par application sur le support, suivie d'un séchage, d'une couche de sa suspension dans un liquide organique contenant un liant organique; les constituants a et c étant présents dans la couche formant la couche contenant le constituant b ou, lorsque le support est perméable à l'ammoniac, les constituants a et c étant présents dans une couche séparée produite par application au recto du support, suivi d'un séchage d'une solution aqueuse contenant les constituants a et c, ladite couche séparée étant placée entre le support et la couche contenant le liant et le constituant b.The present invention relates to a two-component material for diazocopy, which can be developed by heat, characterized in that it comprises a support having on the front side a light-sensitive coating containing a diazonium compound and a coupling agent and which , contains, as a thermal developing agent, a) an ammonium salt having a melting point of at least 115 degrees C, b) a salt of an alkali metal or an alkali earth metal or an oxide or alkaline earth metal hydroxide, and c) an amine salt of an acid having a dissociation constant of at least 10 ** - 3 and capable of melting on heating at a temperature between 70 and 100 degrees C, component b of the developing agent being present in a layer produced by applying to the support, followed by drying, a layer of its suspension in an organic liquid containing an organic binder; components a and c being present in the layer forming the layer containing component b or, when the support is permeable to ammonia, components a and c being present in a separate layer produced by application to the front of the support, followed by drying an aqueous solution containing components a and c, said separate layer being placed between the support and the layer containing the binder and component b.
