Abstract:
1. A process for printing or coating a substrate, which comprises: i) applying to said substrate, and, if appropriate, aligning on said substrate, a liquid-crystalline composition comprising: and at least one compound of the formula Ib where the variables, independently of one another, are as defined below: P is hydrogen, a-Y Z R is hydrogen or C A M and M wherein T Y r is 0, 1, 2 or 3, wherein T wherein Z B) one or more further additives selected from the group consisting of C) optionally one or more further additives selected from the group consisting of D) one or more further additives selected from the group consisting of E) if desired, one or more further additives selected from the group consisting of one or more light stabilizers, one or more heat stabilizers, and one or more oxidation stabilizers that stabilize the liquid-crystalline composition against light, heat and/or oxidation, and ii) applying at least one further non-liquid-crystalline print or at least one further non-liquid-crystalline coating, where said non-liquid-crystalline print or said non-liquid-crystalline coating comprises one or more IR- or UV-absorbent or fluorescent dye or pigment, or carrying out steps i) and ii) in the reverse sequence, and iii) if desired, applying at least one absorption layer and/or protective layer and/or thermally activatable adhesive layer, and iv) curing said liquid-crystalline composition produced in step i) and/or said non-liquid-crystalline print or said non-liquid crystalline coating produced in step ii), wherein said process forms a multilayer structure comprising said substrate; and, on said substrate, a liquid crystalline layer comprising said liquid-crystalline composition, and a non-liquid crystalline layer comprising said one or more IR- or UV-absorbent or fluorescent dye or pigment.
