The present invention relates to compounds of ester derivative of resveratrol, compositions comprising ester derivatives of resveratrol, processes for synthesizing an ester of resveratrol, and use thereof.

Disclosed herein is a fluorescent compound represented by the following general formula and having fluorescence characteristics that vary in the presence of a subject substance, ##STR00001##
wherein R.sub.1 and R.sub.2 each independently represent a carboxyl group, or a substituent containing a carboxyl group, and R.sub.3 and R.sub.4 each independently represent a hydrogen atom, an alkyl group, an alkoxy group, a halogen atom, a hydroxyl group, a carboxyl group, or a substituent containing a carboxyl group.

The present disclosure is a stilbene-based compound or a salt thereof represented by a following formula (1), wherein a group X represents a nitro group or an amino group optionally having a substituent; a group Y represents an amide group optionally having a substituent or a naphthotriazole group optionally having a substituent; and p and q each independently represent an integer of 0 to 2.

##STR00001##

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 (1a) or Formula (1b): ##STR00001##
where R.sub.1 to R.sub.7 are substituents, X.sup. is an anion, and the compound of Formula (1b) has at least one anionic substituent.

A thermal transfer recording sheet includes a substrate, a yellow coloring material layer, a magenta coloring material layer, a cyan coloring material layer, and a protective layer. The yellow coloring material layer, the magenta coloring material layer, the cyan coloring material layer, and the protective layer are frame-sequentially arranged over the substrate. The protective layer contains a compound represented by formula (1):

##STR00001##

where each A is independently CH or CHC.sub.6H.sub.4, each Y is independently an oxygen atom or a sulfur atom, and R.sub.1 and R.sub.2 are each independently a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.

The present application relates processes that can be used to produce encapsulated benefit agents comprising a core and a shell that encapsulates said core, encapsulated benefit agents produced by such process and products comprising such encapsulated benefit agents as well as methods of making and using such products. Such process can be used to produce particles that offer the desired protection and release benefits when used in a varity of products.

A series of carbohydrate-dye conjugates, as well as a method for detection of pathogenic or other organisms (e.g., bacteria) using the same are provided. The carbohydrate-dye conjugate can be enzymatically incorporated into live and active (viable) bacteria of interest for facile detection of said bacteria. The conjugate incorporation is achieved by utilizing one or more of the enzymes that are endogenous to the bacteria of interest, which can incorporate the conjugate via the conjugate's carbohydrate. A detectable signal is produced by the conjugate's dye only upon incorporation into the bacteria of interest, due to the changes in the dye's local environment upon incorporation. The conjugate may be metabolically incorporated into the fatty outer membrane of a bacterial cell wall, which provides a distinctly hydrophobic environment for the conjugate's dye, causing it to produce a detectable signal.
