The invention relates to a photopolymer formulation comprising specific aromatic glycol ethers as writing monomers, matrix polymers and a photoinitiator. The invention further provides an unexposed holographic medium obtainable using an inventive photopolymer formulation, and an exposed holographic medium obtainable by exposing a hologram into an inventive unexposed holographic medium. The invention likewise provides a visual display comprising an inventive exposed holographic medium, for the use of an inventive exposed holographic medium for production of chip cards, identification documents, 3D images, product protection labels, labels, banknotes or holographic optical elements, and specific aromatic glycol ethers.
Epoxy-acrylic macromolecular compounds on the basis of phenol and para-alkyl substituted phenol

Some phenolic glycidyl ethers and suitable acrylic monomers on the basis of phenol and para-alkyl [-CH3, -C(CH3)3, -C9H19] substituted phenols were synthesized and characterized. The monomers were thermally polymerized in the presence of benzoyl peroxide. The polymerization reaction was studied by viscometry, as well as by curing process. The synthesized polymers degrade statistically by a radical mechanism. The apparent thermal stability is higher for para-tert-butylphenol epoxy-acrylic polymer and lower for phenol epoxy-acrylic polymer.
