An ink composition includes resin particles, one or more surfactants, one or more water-soluble organic solvents, and a glycol ether, where: the surfactants include a fluorosurfactant having a predetermined structure and an HLB value determined by Griffin's method of 11 or less; the water-soluble organic solvents include one or more selected from the group consisting of glycerin, ethylene glycol, diethylene glycol, polyethylene glycol having a weight-average molecular weight of 10,000 or less, 1,3-propanediol, 1,4-butanediol, and diglycerol; and the glycol ether has a predetermined structure and an HLB value determined by Griffin's method of 11 or less.

The present disclosure relates to an inkjet printing ink and application thereof. In one aspect, the inkjet printing ink includes a crosslinking type organic host material, an organic doped luminescent material, a surface tension modifier, a viscosity modifier, and a solvent. On the other aspect, the present disclosure provides printing the inkjet printing ink on a substrate of a display panel to be prepared, performing drying process, and performing baking process at 120° C. to form an organic light emitting layer. Therefore, avoiding the problem of mutual dissolution of the organic light emitting layer and the electron transport layer when the electron transport layer is printed on the organic light emitting layer, avoiding damage to the organic light emitting layer, realize an inkjet printing process of the organic electron transport layer, thereby reducing the cost of manufacturing.

According to one aspect of an inventive concept, an ink includes a nonradiation-curable pre-polymer having at least two nonradiation-curable components per molecule of the nonradiation-curable pre-polymer, a radiation-curable component, a polymer having at least one reactive hydrogen component, and a photoinitiator. A concentration of the nonradiation-curable pre-polymer having at least two nonradiation-curable components is in a range of greater than 0 weight % to less than 99 weight % of a total weight of the ink.

The present invention provides water-based ink and coating compositions having a high renewable resin content. The ink and coating compositions of the invention comprise equal to or greater than 65% (w/w) renewable resins, based on the total combined weight of the resins. Renewable resins derived from gum rosins are preferred. The ink and coating compositions of the present invention exhibit physical properties (e.g. adhesion and resistance) that are as good as, or better than, current commercially available inks (e.g. acrylic based inks not containing renewable material).
