A composition for forming a light-emitting device, a method of manufacturing a light-emitting device utilizing the composition, and a light-emitting device manufactured utilizing the composition are provided. The composition includes two or more solvents and a boiling point of a first solvent having the highest boiling point among the two or more solvents is greater than 300° C.

Provided in the present invention is a novel diaroyl carbazole compound, used together with a carbazolyl oxime ester photo initiator to show a significant synergistic initiation effect in a photoresist composition; the best sensitising effect is shown when the molar ratio of the diaroyl carbazole compound and the carbazolyl oxime ester photoinitiator is 0.1-1.4

The present invention relates to an aqueous pre-treatment liquid for use in ink jet printing, the pre-treatment liquid comprising water and magnesium-disulfamate. Such pre-treatment composition is and yellowing and crystal-free and shows good jetting properties. These properties are retained even when a solid co-solvent is added to the composition for anti-curl improvement. Therefore, the present invention enables providing non-yellowing pre-treatment liquids with good jetting properties and anti-curl behavior.
