摘要:A thermosensitive recording material comprising a thermosensitive layer provided on a substrate, and the thermosensitive layer comprises as main ingredients a leuco dye and a developer to make colored state of said leuco dye when heated, wherein the developer is an oligomer composition obtained from the reaction of a polyvalent isocyanate compound represented by following Formula (I) with an aromatic amine represented by following Formula (II); n nwhere X represents a try- or more-valent group, a represents an integer numeral of 3 or more, b and c represent respectively integer numerals in the range of 0 to 5 and they satisfy a relation of b+c=1 to 5, Z represents hydrogen atom, alkyl group, allyl group or aryl group, and the aryl group may include condensed ling structure thereof, and d represents an integer numeral in the range of 0 to 4. This developer shows excellent reliabilities of both image and background area, and also shows an excellent color-developing characteristics (color developing sensitivity and image density).
