Method and master for producing a volume hologram

A method for producing a volume hologram with at least one first area in a first color and at least one second area in a second color, the method comprising:

• a) providing a volume hologram layer made of a photopolymer;
• b) arranging a master with a surface structure on the volume hologram layer;
• and
• c) exposing the master using coherent light, wherein light which is incident on at least one first partial area of the surface of the master is diffracted or reflected in the direction of the at least one first area of the volume hologram layer and light which is incident on at least one second partial area of the surface of the master is diffracted or reflected in the direction of the at least one second area of the volume hologram, and wherein the light diffracted or reflected by the first and second partial areas differs in at least one optical property,
• wherein the exposure takes place in at least two successive exposure steps, and
• wherein at least one of the exposure steps is carried out over the whole surface of the two partial areas such that the at least one first area in a first color of the volume hologram is produced in a desired fixed positional register relationship with respect to the at least one second area in a second color of the volume hologram.
