A security article is provided having a multicoloured image and which comprises a first layer of transparent polymeric material carrying parts of an image formed in a first colour; and at least one other layer of transparent polymeric material carrying parts of the image formed in a different colour. The layers are laminated together with the parts of the image formed in the first and different colours superposed over one another, whereby the colours combine to form a multicoloured image in the laminated security article. In one embodiment, the multi coloured image is viewable from both sides of the security article, and in another form an opaque layer may be provided on one side of the transparent layers to provide a background for viewing the image in reflection from one side of the article.
