Abstract

Materiale de copiat sensibile la presiune pe baza unei mase de cuplare si a unei mase de acceptor de colorant care reactioneaza cu masa de cuplare, caracterizat prin aceea ca masa de acceptor de colorant contine drept componenti de reactie o clorura de zinc sau de fier (III), de crom (III), de vanadiu (III), de cupru (II) sau de mangan, eventual împreuna cu ureea sau derivatii acesteia, împreuna cu un liant ales dintre ceara de polietilena cu greutatea moleculara 400...12000 sau un compus de polivinil, sau clorura de polivinil, sau un copolimer ai acestor compusi si plastifianti, stearati de cobalt sau zinc, rasini naturale si sintetice sau eventual caolina si silice, masa de cuplare consta într-un intermediar de colorant sau încorporat în liant, care reactioneaza cu acceptorul de colorant generînd culoarea, masa de acceptor de colorant si masa de cuplare putînd fi aplicate pe un suport în cantitati de 0,5...6g/,2m2.Pressure-sensitive copying materials based on a coupling mass and a dye acceptor mass which reacts with the coupling mass, characterized in that the dye acceptor mass contains zinc or iron (III) chloride as reaction components ), chromium (III), vanadium (III), copper (II) or manganese, optionally together with urea or derivatives thereof, together with a binder selected from polyethylene waxes with molecular weight 400 ... 12000 polyvinyl compound or polyvinyl chloride, or a copolymer of these compounds and plasticizers, cobalt or zinc stearate, natural and synthetic resins, or possibly kaolin and silica, the coupling mass consists of a dye intermediate or incorporated in the binder reacts with the color acceptor generating color, the dye acceptor mass and coupling mass can be applied to a support in amounts of 0.5 ... 6 g / m2.
