摘要:在单罐策略中,我们已经获得了一种从二硫代氨基甲酸盐/胺开始合成有机氰胺的有效方法.在这种策略中,原位反应生成的烷基或芳基异硫氰酸酯是通过将二硫代氨基甲酸盐与二乙酰氧基碘苯(dib)脱硫而获得的,与氨水反应反应生成烷基或芳基硫脲,随后再用dib进行氧化脱硫,从而形成了相应的氰胺.产量.温和的反应条件,较短的反应时间,对环境有益的方案以及所需产物的容易分离,使得本方法学成为制备各种有机氰胺的合适替代方法.

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).
