The present invention provides an anion exchange resin capable of producing an electrolyte membrane for a fuel cell, a binder for forming an electrode catalyst layer and a battery electrode catalyst layer. The anion exchange resin of the present invention has a hydrophobic unit, a hydrophilic unit and divalent fluorine-containing groups. The hydrophobic unit has divalent hydrophobic groups composed of one aromatic ring or a plurality of aromatic rings that are repeated via carbon-carbon bond. The hydrophilic unit has divalent hydrophilic groups composed of one aromatic ring or a plurality of aromatic rings, at least one of which has an anion exchange group, that are repeated via carbon-carbon bond. The divalent fluorine-containing groups have a specific structure and are bonded via carbon-carbon bond to the hydrophobic unit and/or the hydrophilic unit and/or a moiety other than these units.

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.

Disclosed are a polymer including a structural unit represented by Chemical Formula 1 and a structural unit represented by Chemical Formula 2, an organic layer composition including the polymer, and a method of forming patterns using the organic layer composition. ##STR00001## The Chemical Formulae 1 and 2 are the same as defined in the specification.
