Abstract: A heat printing sheet is prepared by coating a base with a molten printing composition which comprises 10 - 60% by weight of at least one tackifier selected from the group consisting of terpene resins, hydrogenated cyclopentadiene resins, cumarone-indene resins, phenol resins, styreneolefin copolymers, .alpha.-methylstyrene-vinyltoluene copolymers, rosins, polyol esters, hydrogenated rosins, hydrogenated rosin-polyol esters and rosin; 5 - 50% by weight of at least one wax selected from the group consisting of plant wax, petroleum wax, coal wax, synthetic wax; 10 - 60% by weight of an ethylene-vinyl acetate copolymer which contains 5 - 50% by weight of a vinylacetate component and which has a melt index of 4 - 1000 g/10 min, 5 - 40% by weight of a filler which is bendable with said tackifier, wax or ethylene-vinylacetate copolymer; and a pigment.
