The present invention discloses a adhesive sheet effectively blocking light in the ultraviolet light region without deteriorating the transmittance with respect to the visible light region and the adhesiveness and a adhesive composition including binder resin and light absorption dye dispersed in the binder resin, and it is possible to effectively block light under the 410 nm wavelength region and to be applied to a various kinds of display devices.

The present invention relates to novel methine dyes, methods for the preparation thereof and use thereof for dyeing plastics, especially polyamides, so as to obtain yellow colorings with improved light fastness and improved thermostability.

Provided are a protective sheet and a spectacle lens including at least one dye selected from the group consisting of a dye represented by Formula (1) and a dye represented by Formula (2), and application thereof. In Formula (1), R.sup.71 to R.sup.74 each independently represent a hydrogen atom, an alkyl group, an alkoxy group, or the like. In Formula (2), R.sup.21 represents an alkyl group, an aryl group, a heterocyclic group, or the like, R.sup.22 represents a hydrogen atom, a halogen atom, an alkyl group, or the like, and at least one of R.sup.21 or R.sup.22 is an alkyl group having 4 or more carbon atoms. n represents 0 or 1, and m represents an integer of 1 to 5.

An object of the invention is to provide a coloring composition with which a light absorption anisotropic film maintaining an excellent dichroic ratio and having good pressing resistance can be formed, and a light absorption anisotropic film, a laminate, and an image display device using the coloring composition. A coloring composition according to the invention contains: a polymer compound having a repeating unit including a crosslinkable group and a mesogenic group in the same side chain, or a polymer compound separately having a repeating unit including a crosslinkable group in a side chain and a repeating unit including a mesogenic group in a side chain; and a dichroic dye compound.

In a thermal transfer recording sheet including a base material and a colorant layer, the colorant layer includes a yellow dye layer containing a yellow dye, a magenta dye layer containing a magenta dye, and a cyan dye layer containing a cyan dye, and the cyan dye includes a compound represented by Formula (Ia) or Formula (Ib):

where R.sub.1 to R.sub.7 are substituents, X.sup. is an anion, and the compound of Formula (Ib) has at least one anionic substituent.

An object of the present invention is to provide a thermal transfer recording sheet that enables images having a wide color gamut, a high chroma, and good lightfastness, in which the degree of catalytic fading is reduced, to be formed. The thermal transfer recording sheet includes a base material and a colorant layer on the base material. The colorant layer includes a yellow dye layer, a magenta dye layer, and a cyan dye layer. The dye layers each include, as a dye, a compound having a specific structure.
