    • PROBLEM TO BE SOLVED: To obtain a color composition having clear color and high coloring power, exhibiting high light resistance and heat-resistance and free from sublimation property by including a specific yellow pigment containing a perylenebiscarbonyl residue and a resin. SOLUTION: The objective composition contains (A) a yellow pigment having a chemical structure containing perylenecarbonyl residue and expressed by formula I, preferably a yellow pigment of formula II (R and R' are each a >=3C alkyl), or the like, and (B) a resin. The composition is preferably a solid, paste or liquid composition containing the component A at high concentration and the content of the component A is preferably 70-10 wt.%. A clear and lively image having high transparent feeling can be stably recorded by the use of the composition. It has remarkably excellent effect also in fastness such as non-migrating property and non-sublimability.
    • 要解决的问题为了获得具有清晰颜色和高着色力的颜色组合物,通过包含含有苝二羰基残基和树脂的特定黄色颜料,获得了耐光性和耐热性高且不升华性能的颜色组合物。 解决方案:目标组合物含有(A)具有含有苝羰基残基并由式I表示的化学结构的黄色颜料,优选为式II的黄色颜料(R和R'各自为> = 3C烷基)等, 和(B)树脂。 组合物优选为含有高浓度成分A的固体,糊剂或液体组合物,组分A的含量优选为70〜10重量%。 可以通过使用该组合物来稳定地记录具有高透明感的清晰活泼的图像。 在非迁移性和非升华性等牢度方面也具有非常优异的效果。
