Abstract

Emulsione fototermografica in grado di produrre un'immagine cian ad alta densità dopo esposizione a guisa di immagine e sviluppo termico ad una temperatura relativamente bassa e per un breve periodo di tempo. L'emulsione fototermografica dell'invenzione comprende: (a) un legante; (b) un materiale fonte di argento; (c) un alogenuro d'argento sensibile alla luce in prossimità catalitica a tale materiale fonte d'argento; (d) un colorante leuco clan cromogenico.L'emulsione fototermografica dell'invenzione può essere usata per ottenere buone immagini cian di densità adatta in articoli fototermografici di colore singolo o multicolori. Allo stesso tempo, il colorante leuco cromogenico è abbastanza stabile da non essere ossidato dall'ossigeno dell'aria o per semplice riscaldamento e da prevenire la formazione di velo dopo sviluppo.
