JPEG0007865446000018.jpg29169 In formula (1), X and Y are each independently alkyl groups, and at least one of X and Y is a branched alkyl group.

The application discloses a hair dyeing molecule for improving hair dyeing color fastness and hair oxidation resistance performance and a synthesis method thereof. The hair dyeing molecule is prepared by esterification or amidation reaction of a natural pigment molecule with a phenolic hydroxyl group, an alcoholic hydroxyl group, an amino group or an imino group structure and an organic acid containing an alpha, beta-carbon-carbon double bond, so as to obtain a natural pigment molecule derivative with an alpha-carbonyl carbon-carbon double bond structure. The improved pigment molecule is connected to the keratin of the hair through a chemical bond by a thiol click reaction, so that the pigment residence performance is greatly improved, and the color fastness effect is improved.

The invention relates to a display device and an electronic device. The display device may include a display panel, a touch sensing layer, and a reflection adjustment layer. The touch sensing layer may include a touch insulating layer. The touch insulating layer may include a colorant and may cover the first light emitting region. The reflection adjustment layer may be disposed on the touch sensing layer. The reflection adjustment layer may include a first adjustment portion, which is a non-polarizing portion, and a second adjustment portion, which is a polarizing portion. The first adjustment portion may cover the first light emitting region, and the second adjustment portion may cover a second light emitting region. The display panel may be configured to emit light of a first wavelength band through the first light emitting region, and the touch insulating layer may be configured to selectively transmit light of the first wavelength band.

The present invention relates to a series of novel indigo-type structures, alizarin-type structures and anthraquinone-type structures comprising various substituents, and methods for their synthesis. In one aspect the invention provides a dye comprising one of novel structures. Embodiments of the present invention stem from the realization that it is possible to add pendant or functional groups to certain natural compounds, particularly indigo, alizarin and anthraquinone based compounds to improve their textile dyeing properties to be competitive with fossil fuel based dyes.

There is a laminate including: a semiconductor substrate; a support substrate that is light-transmissive; and an adhesive layer and a release layer provided between the semiconductor substrate and the support substrate, the laminate being used when the release layer absorbs light irradiated from a side of the support substrate and then the semiconductor substrate and the support substrate are separated from each other, wherein the release layer is formed from a release agent composition, the release agent composition contains a light-absorbing compound having a molecular weight of 2,000 or less, and when the light-absorbing compound is measured for an absorption spectrum in a range of 250 to 800 nm, the absorption spectrum has a local maximum value, which is a maximum absorbance in a range of 250 to 800 nm, between 250 nm and 350 nm.
