Embodiment 1

[0081] The ink formulation consists of the following substances:

[0082] Crystal violet lactone (Pergascript Blue) SRB-P (such as Ciba, 1.7g), Yamada yellow Y-726 (such as Yamada, 2.8g), benzotriazole cresol (Tinuvin) 770DF (such as Ciba, 0.6g), color can be Polyplast PY-383 (such as Sericol company, 56g), color can diluent ZV-557 (such as Sericol company 35.5g) and Cyracure UVI photoinitiator UVI-6992 (such as Dow company, 3.4 g).

[0083] This ink formulation was printed onto 50 micron white PET film using a 30 micron K-bar and RK proof printer.

[0084] 10,12-Pacosadiynoic acid (1.25 g), Durotak 180-1197 (19 g) and ethyl acetate (4 g) were mixed together to produce an ink solution.

[0085] Inks were coated onto clear 50 micron biaxially oriented polypropylene film using a 30 micron K-bar and RK proof press.

[0086] The two coating samples were then laminated together.

[0087] Then use a UV laser to generate:

[0088] 1. A linear (one-dimensional) barcode consisting...

Abstract

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.

Description

field of invention [0001] The present invention relates to a method of storing information comprising forming a multi-color code on an item, and to an item comprising a multi-color code. Background of the invention [0002] Machine readable codes such as bar codes, matrix codes and other indicia and symbols are well known in the art. These codes typically include black and white symbols representing information applied to the item. A method of producing unique composite markings on a range of items is described in US patent US2003 / 0121984. The system uses a rotating cylinder-based printing technique to produce markings. However, the process of creating the mark and then applying it to the item has to be done in separate steps, which means the process is rather time-consuming. Contents of the invention [0003] A first aspect of the invention is a method of storing information in or on an item, wherein the item includes a coupler that is selectively irradiated to produce...
