A method for producing an organic microdisk structure 40, which is characterized by comprising: a cladding layer formation step 1 wherein a cladding layer 12 is formed by printing a first ink 11 that contains a fluorine-containing hyperbranched polymer on a substrate 10 by an inkjet method; a core layer formation step 2 wherein a core layer 22 is formed by printing a second ink 21 that contains a laser dye and a triazine-based hyperbranched polymer containing no fluorine on the cladding layer 12 by an inkjet method; and an etching step 3 wherein the cladding layer 12 is etched using a solvent 31 that dissolves only the fluorine-containing hyperbranched polymer. Consequently, an unconventional novel method for producing an organic microdisk structure with use of an inkjet method is able to be provided.

The present disclosure provides a white-light block polymer, an ink composition, and a manufacturing method thereof. The white-light block polymer makes it only necessary to print one ink when using inkjet printing, thereby simplifying inkjet printing processing and meanwhile preventing a crosstalk problem of pixels having different colors of light. The present disclosure makes the ink composition suitable for inkjet printing by properly mixing the white-light block polymer, an organic solvent, a surface tension modifier, and a viscosity modifier in a suitable ratio.

Novel trisazo compounds are disclosed. The compounds are well suited for the dyeing and printing of natural and synthetic materials, especially as recording liquids for inkjet printing.
