THERMALLY RESPONSIVE RECORD MATERIAL ABSTRACT OF THE DISCLOSURE A thermally sensitive record material having a very low abrasive surface comprising a substrate coated with a colorless chromogenic material and a phenolic co-reactant in a binder and including a cross-linked urea-formaldehyde resin pigment as a component thereof. The use of the urea-formaldehyde (UF) resin pigment provides a thermal record material with superior bleed resistance, extremely low abrasivity, thereby reducing wear on imaging tools such as print heads, and improved release properties. The UF pigment also improves the image to background contrast and the efficiency of the action of the co-reactants in the record material.
