Laminate structure
First Claim
1. A security thread laminate comprising a translucent or transparent support layer, a translucent or transparent coloured first lacquer layer, a translucent or transparent second lacquer layer disposed between the support layer and the first lacquer layer and a light-reflecting layer adjacent to the first lacquer layer, wherein the first lacquer layer is incomplete in a region substantially in register with an incomplete region in the light-reflecting layer such that the support layer and the second lacquer layer are partially covered by the first lacquer layer and the light-reflecting layer.

Abstract
The present invention relates to the field of laminated materials and, in particular, to laminates (1) for stamping foils and security threads (1). In one aspect there is provided a laminate (1) for a stamping foil comprising a carrier layer, a translucent or transparent coloured first lacquer layer (5), a translucent or transparent second lacquer layer (10) disposed between the carrier layer and the first lacquer layer and a light-reflecting layer (20) adjacent to the first lacquer layer, wherein the first lacquer layer is incomplete in a region substantially in register with an incomplete region in the light-reflecting layer such that the carrier layer is partially covered by the first lacquer layer and the light-reflecting layer (20).

35. A process for making a laminate for a security thread having a translucent or transparent support layer, a translucent or transparent coloured first lacquer layer, a translucent or transparent second lacquer layer and a light-reflecting layer, the first lacquer layer being incomplete in a region substantially in register with an incomplete region in the light-reflecting layer, which process comprises the steps of:
-
(i) applying the second lacquer layer on to the support layer;
(ii) applying the first lacquer layer on to the second lacquer layer;
(iii) applying the light reflective layer on to the first lacquer layer;
(iv) applying a resist mask on to the light reflective layer to define one or more regions which are not to be removed; and
(v) contacting the laminate and resist mask from step (iv) with at least one chemical so as to substantially remove the light-reflecting layer and the first lacquer layer in regions not covered by the resist mask without removing the second lacquer layer in the regions not covered by the resist mask. - View Dependent Claims (36, 37, 38)
