Abstract
Abstract An ink contains a petroleum-derived asphalt, a colorant, and a carrier for the asphalt and colorant. The asphalt has a softening point from 105° C. to 155° C. and a saturates content not greater than 32% by weight. Preferably at least 50% by weight of the carrier is a material selected from aliphatic oils, aliphatic solvents, and mixtures thereof. A method of making the ink includes granulating the asphalt to a particle size not greater than 2.38 mm (8 mesh), dissolving the asphalt in the carrier, and adding a colorant to the carrier.
