The present invention relates to the field of magnetic machine readable oxidative drying suitable for intaglio printing of security documents. In particular, the invention relates to magnetic oxidative drying ink for intaglio printing on a substrate, said magnetic oxidative drying ink having a viscosity in the range of about 3 to about 60 Pa s at 40&#xb0; C. and 1000 sand comprising a) at least one oxidative drying varnish, b) a plurality of core-shell pigment particles comprising a magnetic core and an external layer made of silver and c) one or more stabilizers selected from benzotriazole compounds.

Intaglio magnetic machine readable oxidative drying inks

The present invention is related to the filed of optically variable security elements comprising a region based on a single cured ink comprising a cholesteric liquid crystal polymer, said region having at least two, preferably at least three, patterns exhibiting, at at least one viewing angle, a different CIE (1976) color index parameter and/or a different position of the selective reflection band for protecting security documents against counterfeiting and/or illegal reproduction. In particular, the present invention relates to processes for manufacturing said features, when the processes comprises the steps of a) applying on a substrate by a rotogravure process with the use of a gravure cylinder having at least two, preferably at least three, different engravings a single cholesteric liquid crystal precursor composition, b) heating the applied composition to bring said composition to a cholesteric liquid crystal state, and c) curing the composition so as to form the region based on a single cured ink comprising a cholesteric liquid crystal polymer.

Rotogravure printing processes for producing optically variable security features

The present invention relates to thiazolium dyes, laundry care compositions comprising one or more thiazolium dyes, processes of making such dyes and laundry care compositions and methods of using same. The dyes, compositions and methods of the present invention are advantageous in providing improved hueing of fabric, including whitening of white fabric, while avoiding significant build up of bluing dyes on the fabric.

Laundry care compositions with thiazolium dye

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.

A method of increasing the solubility and/or dispersibility of a perylene dye in a liquid medium. The method comprises binding the perylene dye to a polymer which is soluble in the liquid medium. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Polymer-bonded perylene dyes and compositions containing same

Coding flake or film including at least two chiral liquid crystal polymer (CLCP) layers with a first CLCP layer that has a first detectable parameter and a second CLCP layer including a second detectable parameter; at least one additional layer including a third detectable parameter, the at least one additional layer comprising a material that is not a chiral liquid crystal polymer; and wherein at least the third detectable parameter is different from each of the first detectable parameter and the second detectable parameter.

Multilayer flake with high level of coding

Method for increasing at least one of the solubility and dispersibility of a quaterrylene and/or terrylene dye in a liquid medium, including binding the quaterrylene or terrylene dye to a polymer which is soluble in the liquid medium. Various aspects relate without limitation to polymer-bonded quaterrylene or terrylene dyes, processes, markings, security features, articles and dye-doped polymers.

Polymer-bonded quaterrylene and/or terrylene dyes and compositions containing same

The present invention relates to thiazolium dyes and laundry care compositions comprising one or more thiazolium dyes. The dyes and compositions are advantageous in providing improved hueing of fabric, including whitening of white fabric, while avoiding significant build up of bluing dyes on the fabric.
