摘要:
The invention relates to a photopolymer formulation comprising matrix polymers, writing monomers, and photoinitiators, wherein the writing monomers comprise compounds of formula (I), where at least one of the radicals R1, R2, R3, R4, R5, R6 is a radical bonded to the aromatic ring via X of formula (II), where, in formula (II), A is a linear or branched hydrocarbon, optionally comprising oxygen or nitrogen, the remaining radicals R1, R2, R3, R4, R5, R6 are, independent of each other, hydrogen or an organic radical, and R7 is hydrogen or methyl. The invention further relates to the use of the photopolymer formulation for producing holographic media.
摘要:
The invention relates to a method for producing holographic films, in which a photopolymer formulation is provided which comprises as constituents matrix polymers, writing monomers, a photoinitiator system, optionally a non-photopolymerizable component and optionally catalysts, radical stabilizers, solvents, additives and other auxiliaries and/or additives. The photopolymer formulation is applied in a planar manner and in the form of a film on a support film and the photopolymer formulation is dried on the support film at a temperature 60 100 DEG C. and are above the temperature T by at least 30 DEG C., and a photopolymer formulation having a plateau module of =0.030 MPa is used.
