ABSTRACT:
A novel thermally responsive record material is disclosed, comprising support having provided thereon in substantially contiguous relationship with electron donating dye precursor, an acidic developer material, a sensitizer, and a binder therefor. The sensitizer comprises at least two components, the first component comprising 2,2-bis(4-hydroxyphenyl)-4-methylpentane and the second component comprising a mixture of dimethyl terephthalate and 1,2-diphenoxyethane, the first component being in a range of weight ratios from 1:2 to 2:1 relative the second component, said second component comprising from 50 to 70% dimethyl terephthalate. The sensitizer is prepared by admixing the first component and the second component and grinding the sensitizer to a particle size of less than 1 micron.
