    摘要: It is provided with a thermal recording material having a support coated with a coating solution as a color developing layer. The color developing layer has a colorless dye precursor which is normally colorless or light-colored, and a developer which reacts with the dye precursor to cause color development thereof upon heating. The developer is a bisthiourea compound represented by, for example, a formula (A-2): ##STR1## and the thermal color developing layer contains no sensitizer. In the thermal recording materials of the present invention, substantially no color is developed at a temperature of 120.degree. C. while color development can be caused in response to heating with a thermal head or a laser beam. The developed color on the material can be erased upon contacting with alcoholic solvents, depending on the thiourea compound contained in the color developing layer. After erasure of the image, the material can be used again for recording with a thermal head or a laser beam.

    摘要: A dispersion of a carbonate type blocked color developer having a hydroxyl group having a color developing function which is blocked by an O-substituted oxycarbonyl group (--(C.dbd.O)OR.sub.1), and a metal salt of an organic acid or inorganic acid or a leuco dye are mixed to obtain an opaque undeveloped coating color, and the coating color is coated on paper or the like to obtain a recording sheet. Also, the coating color is further mixed with a light absorbent to obtain an opaque undeveloped coating color, which is coated on paper or the like to obtain an optical recording sheet.

    摘要: An optical recording medium including a substrate having thereon a recording layer containing a dye precursor, a color developer reactable with the dye precursor to develop a color, and a light absorbent for converting light to heat, characterized in that the color developer is at least one compound of Formula (1): (R--NH (C.dbd.S) NH)n--Z (1) (wherein R denotes a substituted or unsubstituted alkyl, cycloalkyl, aryl, aralkyl, or alkenyl. n is an integer of 2 or more, and Z denotes a group having a valence of 2 or more.). The optical recording medium is superior in heat resistance and plasticizer resistance of the recorded image, heat resistance of background, water resistance, and moisture resistance.).
