Thermal imaging medium:
Direct thermal
Layer 4-6 and 10 thermal barrier properties and hot transfer performance allow to adopt the thermo-contact of selection to realize the hot document image of high-quality gray scale form respectively.Can assemble active direct thermal by various systems known in the art, and be disclosed in many patents, for example United States Patent(USP) Nos. 3539375,3674535,3746675,4151748,4181771,4246318 and 4470057, they introduced by reference at this.In these systems, the colourless or light color-producing bodies and the acid color developer material on basis are included in the suprabasil coating, and when being heated to suitable following time of temperature, their fusions or softening allow described substance reaction, thereby produce painted mark.The recording materials of thermal response have the heat of feature replys, thereby in case selective thermal exposes, produces the rendered image of sufficient intensity then requiredly.The effect hypograph of heat be irreversible and part because the barrier properties of layer 8 and 10 causes having unusual stability.In laminate structure of the present invention, can select active direct thermal with anti-when the background variable color that is exposed to the high thermal environment following time that surpasses 190.
The solid that active direct thermal is dewatered at ambient temperature typically.Form basically by the electron donor dyestuff former (being also referred to as color-producing bodies) and the acidic developer material of colourless state by being in for one-tenth color system of the present invention.Dye-forming reaction depends on fusion, softening or one or more components that distil, and adding lustre to the reactivity of chromophore with realization contacts.Colourless basically among the present invention is interpreted as being meant colourless or light or light color.
The component of active direct thermal is with continuous basically relation, be evenly distributed in whole coating layer or be deposited in the suprabasil layer basically.Term is interpreted as continuously basically being meant that the quality component fully arranges in abutting connection with ground among the present invention, in case make and fusion, softening or one or more components that distil then are implemented in the reactive quality contact between each component.Skilled those of ordinary skill in the art it is evident that therefore these reactive component can perhaps use the independent component of multilayer to be positioned at independent stratum in one or more layers identical coating layer.In other words, a kind of component can be positioned at ground floor and other reactive component and can be positioned at subsequently one or more layers.All this this paper of being arranged in are interpreted as continuous basically.
The weight ratio of acidic developer and dyestuff former preferably maintains 1: 1 to about 2: 1.These become the component of color systems to be insoluble to basically in the dispersion medium (preferred water), and typically are ground into less than 10 microns, preferably less than 3 microns independent granularity.
