Abstract

See full text

The present invention relates to a method for producing a micropattern on a substrate (22), in which

    a substrate (22) is provided with a relief pattern (26, 28) that exhibits elevations (26) and depressions (28), and in which the elevations (26) and/or depressions (26) are arranged in the form of the desired micropattern, andwith a printing tool, an imprint material (30; 34) is transferred to the relief pattern (26, 28), the viscosity of the imprint material (30; 34) being chosen such that the imprint material (30; 34) is selectively transferred either substantially only onto the elevations (26) or substantially only into the depressions (28) of the relief pattern.
