PRINT RECEPTIVE COATINGS
Cross Reference to Related Application
This is a continuation-in-part of U.S. Application 20701, Serial Number 07/364,793 filed on June 9, 1989.
Background of the Invention
Nonimpact printing is performed by application of a toner or other print medium, collectively referred to hereinafter as "toner," to a substrate such as by ion deposition printers, laser printers, Xerox brand type printers, ink jet printers and thermal transfer printers. A wide variety of substrates are used with such printing such as paper, plastics and vinyl.
The adhesion of the toner to such substrates is not entirely satisfactory. During normal handling, abrasions to the toner printed on substrates will cause portions to come loose, particularly toner printed with ion deposition printers where the toner is only pressure fused to the substrate. Laser printers and Xerox brand type printers provide for a little better adhesion because they fuse the toner to the substrate by pressure and heat.
A need exists to improve such adhesion and to make toners abrasion resistant. These objectives are the subject of the instant invention.
Summary of the Invention
It has been found that improved toner adhesion and resistance from abrasion can be achieved, particularly for toners fused by pressure alone at room temperature. This improved adhesion is achieved by applying to the printing substrate a polymeric film forming material suitable for forming a print-receptive coating which when cured or dried will have a dynamic storage tensile modulus ranging from about .01 x 10 9 to about 26 x 109 dynes per square centimeter when measured on a Rheometriσs Mechanical Spectrometer, model 800, at 25βC at a frequency of 10 radians per second using the film fixture attachment. At this modulus range the coating will be soft enough to deform and accept the toner without undue smearing and without allowing the toner to come loose from the coating during normal handling, but without being so soft as to cause one sheet of paper to adhere to the next or jam when contacted by rollers in a printing machine.
While the print receptive coating can be beneficially applie -to a wide variety of substrates, the preferred substrate will be a compressible substrate with the most preferred a porous, compressible substrate such as paper or a pressure sensitive label construction.
Virtually any polymeric film forming material may be used as a coating, provided that it is suitable for forming a print-receptive coating and has a modulus range as specified above, when cured or dried.
The polymeric film forming materials used to form the coating of the present invention may be prepared and applied to the substrate and cured or dried thereon using water based emulsions or organic solvent systems, or using 100% solids reactive systems which are cured by ultraviolet (UV) or electron beam radiation before transfer of the toner. The coating viscosity of the print receptive coating should be high enough to prevent undue soak into the most preferred porous substrate.
The coatings have utility as a surface for single cut sheets or for label face stock. They are particularly useful for printed bar codes in preventing the contact bar code reader from abrading off the bar code image and making the bar code unreadable.
Particular polymeric materials suitable for use in forming coatings of the 100% solids reactive system of the present invention are acrylated oligomers and mixtures therefore, and oligomers selected from the group consisting of acrylated urethane oligomers, acrylated epoxy oligomers and polyacrylic oligomers.

The dynamic storage tensile modulus, E1, the dynamic tensile loss modulus E", and the loss tangent (tan d = E"/E') , of each formulation of Table I is set forth in Table Iϊ below wherein each cured formulation is ranked as its modulus increases from the softest coating, No. 12, to the hardest coating, No. 7.
Table II also sets forth the modulus of each formulation using a frequency of 10 and 100 Radians per second for the sake of comparison. It is believed that the time of 0.1 sec (corresponding to a frequency of 10 radians/sec) approximates the time that pressure is applied to any given toner particle during the fusing operation and that the coating modulus at that frequency is the important parameter for determining toner adhesion and abrasion resistance.
Ultraviolet curable coatings applied to a 20 pound per ream ion deposition grade bond paper manufactured by Boise Cascade Co. were cured with two 300 watt per inch medium pressure mercury vapor UV lamps. The coating viscosity at application ranged from 350-2500 cps. as measured by a Brookfield viscometer with a number 6 spindle at 100 RPM. Under these conditions, good surface coatings were provided onto the surface with no detrimental penetration into the porous sheet. Line speed was 70 feet/minute with the application to drying distance of 24 inches, giving a time to cure of 1.7 sec. All coatings had a surface energy greater than 30 dynes/cm 2.
The ultraviolet curable coatings were applied by flexographic techniques, but other coating techniques known in the art may be utilized. The required weight of the coatings are from 0.5 to 5 grams/meter 2.

Table III sets forth measurements of how well toner adheres to the coatings of the present invention. The coatings were applied to 20 pound bond paper as aforesaid.
The toner was printed on said coated paper by fusing the toner thereon by pressure alone by a C. Itoh electronics model Megaline/30 printer using a Delphax engine S-3000 operating at room temperature using an alpha numeric test pattern as the image. No transport problems were experienced through this multiroll machine indicating excellent performance against jamming or blocking. The toner was Delphax Monocomponent Ion Deposition toner manufactured by Coates Special Products, Kent, England. An adhesive tape (Scotch 610) was applied to toner printed on a sheet of uncoated paper (the control) and to toner printed on eight sheets of coated paper having eight different coating formulations as set forth in Table I, with the results tabulated in Table III. The adhesive
tape removed most of the toner from the uncoated paper but did not remove enough toner from the paper having coating formulations 1 to 8 to adversely affect their readability.
The amount of toner removed as aforesaid is measured in terms of its readability which is measured by a PCM II instrument manufactured by MacBeth Company. The PCM II instrument measures readability in terms of the print contrast, i.e., the reflectivity of the printed image relative to the reflectivity of the paper, to give print contrast readings as set forth in Table III and IV. Print contrast readings are reported in Tables III and IV as 100 times the decimal reading of the instrument, i.e., as a percentage figure. The PCM II has a 0.008 inch reading diameter. The measurements were an average of 5 to 7 readings taken at the intersection of the horizontal and vertical sections of letters such as "B" and "E". Print contrast readings of 70% or above are generally readable.
The Print Contrast measurements set forth in Tables
III an IV were made with the PCM II instrument using a "C" filter with a 3050 K source. The "C" filter has a response range of from about 639 nm to about 1110 nm and a central peak response at 800 nm wavelength.
