Patent EP-0389153-A3 (EP)
Title: Anti-stick layer for thermal printing
IPC: B41M5/382
Filed: 1990-03-09
Abstract: This invention relates to thermal printing, and, in 
particular, to a coating for preventing sticking of thermal 
printing materials to a thermal printhead of a thermal 
printer. In one form of direct thermal printing, colorless 
forms of heat-activatable dyes are incorporated into a 
polymeric binder borne on a suitable carrier. Upon 
application of heat in an imagewide manner, these dyes are 
converted to their colored forms to form an image in the 
dye-containing material. Because commonly used polymeric 
binders are thermoplastic, there is a tendency for them to 
soften in the heated areas and stick to the thermal 
printhead, thereby causing malfunctioning of the printing 
apparatus and reduction in image quality. In thermal 
transfer printing, the printing process occurs by 
heat-activated transfer of image-forming material from a 
donor to a receptor such that the receptor bears the formed 
image. The construction of the donor requires that the 
image-forming material be carried upon a thin, flexible 
backing. The image-forming material may take several 
forms, such as, for example, a meltable colored wax. Many 
of the most suitable backing materials are thermoplastic, 
and therefore have a tendency to soften and stick to the 
printhead during the thermal imaging process, thereby 
causing poor print quality and malfunctioning of the 
printing machine. This invention provides a layer for 
preventing sticking of thermal image-forming materials to 
thermal printheads during thermal printing. The layer 
comprises polymeric material having a non-cyclic, 
substantially completely saturated hydrocarbon backbone, 
said backbone having substantially only hydrogen atoms and 
methyl groups attached to randomly positioned carbon atoms 
thereon, with no more than one methyl group attached to any 
one backbone carbon atom. Solubility of the polymeric 
material in commonly used organic solvents allows very thin 
layers of the coating to be applied in the form of dilute 
solutions.

Title: Thin film electroluminescent edge emitter structure with optical lens and multi-color light emission system
IPC: H05B33/06
Filed: 1990-05-11
Abstract: A thin film electroluminescent edge emitter 
structure [Fig. 1 (10)] includes a common electrode layer 
(12) and control electrodes (20) disposed above the common 
electrode layer. At least one dielectric layer (14 or 16) 
is disposed between the common electrode layer (12) and 
control electrodes, and a phosphor layer (18) is inter­
posed between the one dielectric layer and common elec­
trode layer. The common electrode layer, one dielectric 
layer and the phosphor layer define the light-emitting 
pixels (24) of the emitter structure. Each pixel has a 
light-emitting face (24A) formed thereon and is operable 
upon application of electrical excitation to cause the 
radiation of light energy within its phosphor layer at 
least in a direction towards the pixel light-emitting 
face. An optical lens system [Fig. 3 (36), Figs. 4-7] 
associated with the pixels includes a preselected contour 
(34A) shaped on the light-emitting face of each pixel to 
define an optical lens integral therewith to project the 
light energy passed therethrough in a preselected direc­
tion and form a beam of light energy having a preselected 
beam pattern. A multi-color light emission system [Fig. 
10 (46) ] employed by the pixels includes a plurality of 
phosphor zones (48 (1), (2), (3)) composing the phosphor 
layer and capable of projecting different light energy 
through the light-emitting faces (48A) of the pixels. 
Also, separate edge emitter structures projecting 
 
 
different colors of light can be utilized in a electro­
photographic printer.
