ABSTRACT:
It has been found that improved toner adhesion and resistance from abrasion can be achieved by applying to the printing substrate, a polymeric film forming material suitable for forming a print-receptive coating which when cured, will have a dynamic storage tensile modulus ranging from about 0.01.times.10.sup.9 to about 26.times.10.sup.9 dynes per square centimeter when measured on a Rheometrics Mechanical Spectrometer at 25.degree. C. at a frequency of 10 radians per second. At this modulus range the coating will have a softness to hardness range which will accept the printed toner without undue smearing and without allowing the toner to come loose from the coating during normal handling.
