초록 ▼

A process is provided for producing a pressure-sensitive carbonless record sheet comprising the steps of preparing a hot melt coating composition, the hot melt coating composition being water insoluble and having a melting point of from about 60°C to about 140°C. The hot melt coating composition includes a chromogenic material. The chromogenic material is a meltable color developer of the acidic electron accepting type. The hot melt coating composition is heated to a temperature above its melting point and the heated coating composition is applied to a substrate, the coating composition being applied at a coat weight of from about 0.2 pounds to about 8.0 pounds per 3300 square feet of substrate. The coating composition is set by cooling the coated substrate. A novel liquid chromogenic coating composition is produced, the coating composition having a melting point of from about 60°C to about 140°C and comprising from about 15% to about 100% of a chromogenic material and from about 0% to about 80% of a rheology modifying material, the chromogenic material being a meltable color developer of the acid electron accepting type. A pressure-sensitive record sheet is produced, the record sheet comprising a substrate having a plurality of surfaces, at least one of the surfaces being coated with a set hot melt coating composition, the set hot melt suspending medium including a chromogenic material dispersed therein.
