| 20110151380 | DATA STORAGE MEDIUM - A data storage medium comprising recording information in the form of a track of data points, the colour of each data point being selected from at least three different colours, wherein the recording information is disposed on a substrate which comprises a colour forming composition, wherein said colour forming comprises a colour former which is susceptible to changing to at least three different colours when irradiated with a laser, wherein the colour former is a leuco dye, a diacetylene or a carbazole. Methods of forming the data storage medium and methods of reading the medium are also provided. | 06-23-2011 |
| 20110151384 | Colour Forming Composition - A composition comprising i) a colour forming component which is susceptible to changing colour when irradiated; ii) an amine neutralised alkylaromatic sulphonic acid; and iii) a binder. Methods of marking a substrate comprising incorporating within or applying to a substrate the composition of this invention, and substrates coated with the composition, are also provided. | 06-23-2011 |
| 20110155815 | MULTI-COLOURED CODES - The invention relates to a method of storing information in or on an article, wherein the article comprises a colour former which is selectively irradiated to produce a multi-coloured code comprising at least three different colours. Also provided by the invention is an article comprising a multi-coloured code comprising at least three different colours, obtainable by the method of the invention. | 06-30-2011 |
| 20110159268 | Energy Activated Compositions - A composition susceptible to changing colour upon the application of energy, wherein the composition comprises a colour former and a tinting colourant, wherein the tinting colourant has a complementary colour to that of the composition comprising the colour former without tinting colourant. Preferably, the composition | 06-30-2011 |
| 20110167572 | Textile Colouration - A textile comprising a diacetylene compound which is capable of changing colour when irradiated with light energy. Methods of imparting colour to textiles comprising irradiating the textile with light energy are also provided. | 07-14-2011 |
| 20110171438 | Laser Imageable Paper - A method of manufacturing a paper substrate comprising a colour former which is capable undergoing a light activated colour change reaction, wherein the colour former is applied to the paper substrate during the manufacture of said paper substrate, and the colour former is a metal oxyanion or a molecular organic. A paper substrate obtainable by this method is also provided. | 07-14-2011 |
| 20110183126 | Substrate Marking - The invention relates to a method of marking a substrate comprising treating the substrate with a boron compound and a charrable agent, and, irradiating the areas of the substrate to be marked such that those areas change colour. Marked substrates obtainable by this method are also provided. | 07-28-2011 |
