    摘要： Thermally-responsive record material comprises a support having provided thereon a thermally-sensitive color-forming composition comprising, in substantially contiguous relationship, an electron-donating dye precursor, an acidic developer material, a sensitizer compound of the formula
    and a suitable binder therefor. The presence of the compound of formula (I) enhances the stability, intensity and speed of formation of an image produced in the record material in response to thermal energy input.

    摘要： Thermally responsive record material comprises a support having provided thereon in substantially contiguous relationship in one or more layers an 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 is preferably in a weight ratio of from 1:2 to 2:1, more preferably 1:1, relative to the second component. The second component comprises 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.
