Polycyclic aromatic hydrocarbon compounds having an S atom or S(&#x2550;O)moiety incorporated in their basic polycyclic structure that can have a nitrogen-containing heterocycloaliphatic group and/or a substituted or unsubstituted phenoxy group and/or a polymeric moiety bonded to the polycyclic structure and to compositions such as, e.g., printing inks which comprise these polycyclic aromatic hydrocarbons as colorants.

[object Object]

A polymer-bonded polycyclic aromatic hydrocarbon compound of general formula (1):(P&#x2014;O)-Q-(Y)&#x2003;&#x2003;(1)wherein P represents a polymeric moiety having at least three repeating units which comprise an optionally substituted phenyl ring; Q represents a perylene, quaterrylene or terrylene moiety; Y is selected from (i) halogen and (ii) optionally substituted N-heterocycloaliphatic groups having from 3 to about 8 ring members which are bonded to Q through an N atom, provided that at least one Y represents (ii); x represents an integer of from 1 to 4; w represents an integer of from 1 to 4. Also, are provided processes of producing the compounds, polymers, markings and articles, and methods of authenticating.

Polymer-bonded polycyclic aromatic hydrocarbons having nitrogen containing substituents

The present invention relates to the field of catalytic hydrogenation and, more particularly, to the use of Ru complexes with bidentate ligands, having one amino or imino coordinating group and one phosphino coordinating group, in hydrogenation processes for the reduction of esters or lactones into the corresponding alcohol or diol respectively.

Hydrogenation of esters with Ru/bidentate ligands complexes

The present invention relates to the field of catalytic hydrogenation and, more particularly, to the use of Ru complexes with tetradentate ligands having at least one amino or imino coordinating group and at least one phosphino coordinating group in hydrogenation processes for the reduction of esters or lactones into the corresponding alcohol or diol respectively.

Hydrogenation of esters with Ru/tetradentate ligands complexes

The present invention concerns substituted benzylic nitriles substituted with lower linear alkyl or alkylene groups. These compounds are useful perfuming ingredients, and can impart odor notes of the floral-green type. The invention concerns also the perfuming compositions or perfumed articles associated with the compound.

Nitrile derivatives as perfuming ingredients

The present invention concerns substituted benzylic nitrites substituted with lower linear alkyl or alkylene groups. These compounds are useful perfuming ingredients, and can impart odor notes of the floral-green type. The invention concerns also the perfuming compositions or perfumed articles associated with the compound.

The object of the present patent application are 3-aminophenol derivatives of formula (I) or the physiologically tolerated, water-soluble salts thereof wherein R denotes a heterocyclic aromatic 5-membered ring of formula (Ia) and colorants based on a developer-coupler combination and containing these compounds.

M-aminophenol derivatives and coloring agents containing them

The object of the present patent application are agents for dyeing keratin fibers based on a developer-coupler combination and characterized in that they contain at least one 3-aminophenol derivative of formula (I) or a physiologically compatible, water-soluble salt thereof wherein  

Oxidation hair dyes containing 3-aminophenol derivatives, and novel 3-aminophenol derivatives

The invention relates to an agent for colouring fibres (A). Said agent is produced by mixing two constituents (A1) and (A2), and is characterised in that the constituent (A1) contains at least one quinonimine derivative of formula (I), and the constituent (A2) contains at least one compound from the group consisting of aromatic amines and phenols. The invention also relates to a method for colouring keratin fibres using the inventive agent.
