Patent attributes
An object of the present invention is to provide a binder composition which is excellent in upper layer coatability after being formed as a binder layer and can improve liquid crystal aligning properties, a binder layer, an optical laminate, and an image display device. A binder composition according to the embodiment of the present invention is a binder composition containing: a binder; a polymerization initiator; a surfactant; and a photo-alignment agent, in which the surfactant and the photo-alignment agent include functional groups capable of hydrogen bonding with each other, and the functional group capable of hydrogen bonding included in any one of the surfactant or the photo-alignment agent is a proton-donating functional group, and the functional group included in the other of the surfactant or the photo-alignment agent is a proton-accepting functional group.
