BACKGROUND OF THE INVENTION 
The present invention is directed to transparencies, and more specifically, 
to high projection efficiency, fire resistant, low haze, lightfast and 
waterfast ink jet transparencies with improved ink absorption and ink 
spreading when used in combination with liquid ink compositions and solid 
ink hot melt ink compositions such as those selected for ink jet printing 
processes, and thermal transfer printing. In embodiments of the present 
invention, the transparencies are comprised of a supporting substrate, 
such as paper, or MYLAR.TM., and thereover two coatings, a first coating 
layer which comprises a binder having a melting point in the range of from 
about 100.degree. C. to about 275.degree. C. and preferably from about 
150.degree. C. to 260.degree. C., and a heat dissipating fire retardant 
compound, and a second dye immobilizing light resistant, water resistant 
ink receiving coating layer situated so that the first coating layer is 
between the second dye immobilizing, light resistant, water resistant ink 
receiving coating layer and the substrate, the second coating layer being 
comprised of a blend of a polymer, cationic monomeric or polymeric 
component capable of complexing with the dyes of the ink compositions, a 
lightfastness inducing agent, and or mixtures thereof, a filler, a biocide 
and an ink spreading agent of fluoro compounds, especially aliphatic and 
aromatic compounds containing from 1 to about 25 fluorine atoms, and 
having a melting point of between 50.degree. C. to 100.degree. C. and 
preferably wherein the two coatings, thus a total of four coatings, are 
present on each surface of the supporting substrate. 
With the transparencies of the present invention, there are enabled a 
number of advantages, including the important advantages of high 
projection efficiency due primarily to improved flow of the liquid and 
solid hot melt inks on the ink receiving layers containing low surface 
energy fluoro compounds, and more specifically, in view of the low surface 
tension, about 30 to about 35 dynes/centimeter of the ink receiving layer. 
With the transparencies of the present invention, there are enabled a 
number of other advantages, including the important advantage of fire 
retarding characteristics for the transparencies when used in ink jet 
printers that employ heat or microwave energy for drying inks, low haze, 
that is, for example, wherein the transparencies permit greater than 95 
percent of the light to be transmitted therethrough in embodiments, and 
which transparencies possess excellent lightfastness and waterfastness 
characteristics. The transparencies of the present invention can be 
selected for ink jet methods and apparatus, which employ hot melt wax 
based inks.

need remains for transparencies with excellent low haze characteristics, 
such as haze value of between from about 0.5 to about 10 and preferably 
between 0.5 to 5, a feature not easily obtained considering that the total 
thickness of the two layered coatings can range from about 2 to about 50

satisfactorily projected. A need also remains for transparencies which are 
particularly suitable for use in printing processes wherein the recorded 
transparencies are imaged with liquid and solid inks and dried by exposure 
to radiant heat or microwave radiation. Further, there is a need for 
transparencies coated with a discontinuous, porous film. There is also a 
need for transparencies which, subsequent to being imaged with an aqueous 
liquid or solid ink, exhibit reduced curling. These and other needs are 
achievable with the transparencies of the present invention in embodiments 
thereof.

amount; typically, the biocide is present in an amount of from about 0.1 
microns percent by weight to about 3 percent by weight of the coating, 
although the amount can be outside this range. 
The coatings of the present invention can be applied to the substrate by 
any suitable technique. For example, the layer coatings can be applied by 
a number of known techniques, including melt extrusion, reverse roll 
coating, solvent extrusion, and dip coating processes. In dip coating, a 
web of material to be coated is transported below the surface of the 
coating material (which generally is dissolved in a solvent) by a single 
roll in such a manner that the exposed site is saturated, followed by the 
removal of any excess coating by a blade, bar, or squeeze roll; the 
process is then repeated with the appropriate coating materials for 
application of the other layered coatings. With reverse roll coating, the 
premetered coating material (which generally is dissolved in a solvent) is 
transferred from a steel applicator roll onto the web material to be 
coated. The metering roll is stationary or is rotating slowly in the 
direction opposite to that of the applicator roll. In slot extrusion 
coating, a flat die is used to apply coating material (which generally is 
dissolved in a solvent) with the die lips in close proximity to the web of 
material to be coated. Once the desired amount of coating has been applied 
to the web, the coating is dried, typically at from about 25.degree. C. to 
about 100.degree. C. in an air dryer. 
The drying time of images obtained with the transparencies of the present 
application is the time for zero image offset and can be measured as 
follows: a line comprising different color sequences is drawn on the 
transparency with droplets of inks from an ink jet printhead moving from 
left to right and back. Thereafter, this image is purposely smeared with 
the pinch roll of the printer by fast forwarding the transparency 
mechanically while the pinch roll is on the top of the imaged line. This 
entire procedure takes about two seconds to complete. In the event that no 
offset of the printed image on the unprinted paper or transparency occurs, 
the drying time of the image is considered as less than two seconds. 
Transparencies of the present invention in embodiments exhibit reduced curl 
upon being printed with aqueous inks, particularly in situations wherein 
the ink image is dried by exposure to microwave radiation. Generally, the 
term "curl" refers to the distance between the base line of the arc formed 
by the transparency or recording sheet when viewed in cross-section across 
its width (or shorter dimension, for example, 8.5 inches in an 
8.5.times.11 inch sheet, as opposed to length, or longer dimension, for 
example, 11 inches in an 8.5.times.11 inch sheet) and the midpoint of the 
arc. To measure curl, a sheet can be held with the thumb and forefinger in 
the middle of one of the long edges of the sheet (for example, in the 
middle of one of the 11 inch edges in an 8.5.times.11 inch sheet) and the 
arc formed by the sheet can be matched against a pre-drawn standard 
template curve. 
The transparencies of the present invention in embodiments exhibit little 
or no blocking. Blocking refers to the transfer of ink or toner from a 
printed image from one sheet to another when recording sheets are stacked 
together. The recording sheets of the present invention exhibit 
substantially no blocking under, for example, environmental conditions of 
from about 20 to about 80 percent relative humidity and at temperatures of 
about 80.degree. F. 
Further, the transparencies of the present invention in embodiments exhibit 
high resistance to humidity. Resistance to humidity generally is the 
capacity of a recording sheet to control the blooming and bleeding of 
printed images, wherein blooming represents intra-diffusion of dyes and 
bleeding represents inter-diffusion of dyes. The blooming test can be 
performed by printing a bold filled letter such as "T" on a recording 
sheet and placing the sheet in a constant environment chamber preset for 
humidity and temperature. The vertical and horizontal spread of the dye in 
the letter "T" is monitored periodically under a microscope. Resistance to 
humidity limit is established when the dyes selected begin to diffuse out 
of the letter "T". The bleeding test is performed by printing a checker 
board square pattern of various different colors and measuring the 
inter-diffusion of colors as a function of humidity and temperature. 
The optical density measurements recited herein were obtained on a Pacific 
Spectrograph Color System. The system consists of two major components, an 
optical sensor and a data terminal. The optical sensor employs a 6 inch 
integrating sphere to provide diffuse illumination and 8 degrees viewing. 
This sensor can be used to measure both transmission and reflectance 
samples. When reflectance samples are measured, a specular component may 
be included. A high resolution, full dispersion, grating monochromator was 
used to scan the spectrum from 380 to 720 nanometers. The data terminal 
features a 12 inch CRT display, numerical keyboard for selection of 
operating parameters and the entry of tristimulus values, and an 
alphanumeric keyboard for entry of product standard information. 
Haze values recited herein were measured by an XL-211 Hazegard Hazemeter 
supplied by Pacific Scientific Company. 
The lightfastness values of the ink jet images were measured in the Mark V 
Lightfastness Tester obtained from Microscal Company, London, England.

Specific embodiments of the invention will now be described in detail. 
These Examples are intended to be illustrative, and the invention is not 
limited to the materials, conditions, or process parameters set forth in 
these embodiments. The coatings, a total of four are included on both 
surfaces or sides of the transparency unless otherwise indicated. All 
parts and percentages are by weight unless otherwise indicated. 
EXAMPLE I 
Twenty transparency sheets were prepared by the solvent extrusion process 
(single side each time initially) on a Faustel Coater using a one slot die 
by providing for each a MYLAR.TM. base sheet (roll form) with a thickness 
of 100 microns, and coating the front side of the base sheet with a 
hydrophobic heat dissipating/fire resistant coating comprised of 75 parts 
by weight of polycarbonate, #035, having a melting point of 257.degree. C. 
and available from Scientific Polymer Products, and 25 parts by weight of 
the fire retardant compound polypenta bromobenzyl!acrylate, available as 
FR-1025 from Dead Sea Bromine Corporation, which blend was present in a 
concentration of 5 percent by weight in dichloromethane. Subsequent to air 
drying at 100.degree. C. and monitoring the difference in weight prior to 
and subsequent to coating, the dried MYLAR.TM. base sheet rolls contained 
1.0 gram in a thickness of 10 microns of the hydrophobic heat and fire 
resistant coating. This hydrophobic heat dissipating/fire resistant 
coating was further overcoated on a Faustel Coater using a one slot die 
with a hydrophilic ink receiving layer comprised of a blend of 50 parts by

monitoring the difference in weight prior to and subsequent to coating, 
the dried MYLAR.TM. base sheet rolls contained 1.0 gram in a thickness of 
10 microns of the ink receiving layer. Rewinding the coated side of the 
MYLAR.TM. base sheet (roll form) on to an empty core and using these 
rolls, the uncoated back side of the MYLAR.TM. base sheet was coated on a 
Faustel Coater using a one slot die with the above hydrophobic heat 
dissipating/fire resistant coating blend which was further overcoated with 
the same above ink receiving layer as that on the front side. The 
transparency sheets thus prepared had a haze value of 4.5.

percent by weight of Projet Yellow 1G dye (7.5 percent solution) obtained 
from Zenca Colors, 20.0 percent by weight of Acid Yellow 17 solution 
obtained from Tricon Colors, and 10.12 percent by weight of deionized

percent solids of carbon black and 6.0 percent of dispersant), obtained 
from Bayer A.G of Germany, and 39.90 percent by weight of deionized water. 
Images with 100 percent ink coverage were generated by printing block 
patterns for magenta, cyan, yellow, and black. These images were dried 
with a microwave dryer operated at 2.45 GHz frequency using serpentine 
wave guide mode for periods of one second and two seconds, by adjusting 
the dryer speed. 
At a dryer speed of 4.33 inches per second (resident time of one second in 
the dryer), the resulting dried images yielded optical density values of 
1.95 (black), 1.70 (cyan), 1.60 (magenta) and 0.9 (yellow). These images 
had lightfastness values greater than 90 percent and, more specifically, 
about 98 percent average for all colors after a period of six months, and 
showed no intercolor bleed when retained at a 80 percent humidity at 
80.degree. F. for a period of seven days. The projection efficiency of 
these images were measured at 92 percent. 
At a dryer speed of 2.17 inches per second (resident time of two seconds in 
the dryer) the resulting overdried colored images suffered no image 
degradation due to the crystallization of dyes as observed by the absence 
of dark patches in the imaged colored areas during their projection on a 
3M Model 905 Overhead Projector, and the black area printed with the 
carbon black pigmented ink did not melt away as the excessive heat 
generated by the absorption of microwave energy by the carbon black 
pigmented inks was dissipated over a wider area by the heat 
dissipating/fire resistant protective coating. 
In a comparative study, Hewlett Packard Desk Jet Transparency 51636 F 
printed with a carbon black pigmented ink melted away as the excessive 
heat generated by the absorption of microwave energy by the carbon black 
pigmented inks was not dissipated evenly.

dissipating/fire resistant coating that was present on the front side and 
was further overcoated with the same above hydrophilic ink receiving layer 
as that on the front side using a Faustel Coater with a one slot die. The 
transparency sheets thus prepared had a haze value of 3. 
The above prepared transparencies were incorporated into a Xerox 
Corporation 5760 digital color copier containing low melt polyester dry 
toners, and images were obtained with optical density values of 1.20 
(cyan), 1.15 (magenta), 0.77 (yellow), and which images were waterfast 
when washed with water for 2 minutes at 50.degree. C. and lightfast for a 
period of three months without any change in their optical density.
