PROBLEM TO BE SOLVED: To obtain a fusion-type marking material which is prevented from the occurrence of cracks during aging and from the lowering of softening point and gives a coating material improved in dryability and stain resistance by compounding inorg. or org. fibers with a rubbery elastic resin. SOLUTION: 0.1-10 mass %, pref. 0.5-3 mass %, inorg. or org. fibers having diameters of 3-30 μm and lengths of 500-5,000 μm, pref. 1,000-3,000 μm, 0.1-20 mass %, pref, 1-4 mass %, rubbery elastic resin having an m.p. of 60-140 deg.C, pref. 80-120 deg.C, 10-20 mass % caking resin having a softening point of 90-130 deg.C, pref. 95-125 deg.C, 0.5-5 mass %, pref. 1-4 mass %, plasticizer (e.g. a vegetable oil, a vegetable oil-modified alkyd resin, a mineral oil, an epoxidized oil, or a liq. synthetic rubber), 25-65 mass %, pref. 30-60 mass %, filler (e.g. calcium carbonate or white marble), and 1.5-7 mass %, pref. 2-6 mass %, coloring pigment (e.g. a white or yellow pigment) are compounded. |
