Abstract: Polycyclic aromatic compounds of formula (I) having at least two conjugated aromatic rings at least one of which has a substituent comprising a cyclic carbonate group can be used as sensitisers for cationic photoinitiators, especially iodonium compounds, and may also function as monomers in cationically initiated radiation curable compositions, especially coating compositions, such as printing inks and varnishes.

Abstract: A radiation curable jet ink contains at least 65% by weight of one or more monofunctional ethylenically unsaturated monomers and also contain at least one tri- or higher functional ethylenically unsaturated monomer, and has a surface tension at 25° C. of not more than 36 dynes/cm.
Abstract: A portable authentication device and method of authenticating products or packaging by analyzing key ingredients on products or on product packaging is disclosed. Light-sensitive compounds can be used to identify the product or product packaging. The product or product package may include visible or invisible ink containing a particular light-sensitive compound. The ink may be printed in one or more locations on the product or product packaging to produce an authentication mark, such as a bar code. The device includes an assembly for providing a source of light to irradiate the ink containing the light-sensitive compound on the sample product or product package, an optical detector to detect certain spectral properties emitted or absorbed by the irradiated ink and a controller to determine the authenticity of the sample product or product package by comparing the emitted or absorbed properties to a standard.
