office materials. SUBSTANCE: invention provides correction and marking materials in the form of solids liquified when applied onto substrate. Materials contain dye, pigment or turbidity-conferring substance in solid matrix carrier representing mixture of high-crystallinity aromatic compound with condensed rings and long- chain aliphatic alcohol. When in contact with substrate, material liquefies at least partly and, after precipitation, immediately hardens to form dry layer. EFFECT: facilitated use due to intermediate liquefaction of material. 9 cl, 14 dwg, 25 ex
