GOLD-CONTAINING POLYMERISABLE ACRYLIC COMPOSITION, SPATIAL-MESH POLYMER MATERIAL FOR RECORDING INFORMATION AND PRODUCTION METHOD THEREOF Russian patent published in 2011 - IPC C08L33/08 C08L33/10 C08K3/08 G03C1/725 

FIELD: chemistry.

SUBSTANCE: composition consists of 20-80 pts.wt bifunctional acrylic oligomer, (meth)acrylic groups in which are bound by a divalent organic group with an ester, carbonate or urethane group, 20-80 pts.wt acrylic monomer selected from a alkyl(meth)acrylates or oxyalkyl(meth)acrylates, where the alkyl is a lower alkyl; 5-25 pts.wt gold salt selected from a group of inorganic salts of gold which are soluble in said acrylic monomer; 0.1-3 pts.wt photoinitiator. Also disclosed is a spatial-mesh polymer material containing dissolved gold in zero valence. Under external thermal and/or photo action, said material, which is a colourless and transparent glass-like material with not less than 90% optical transmission in the visible region, is cable of generating a plasma resonance band in the visible region of the formed gold nanoparticles - gives a response point in the 500-640 nm range. the material is obtained through photo-exposure of the said gold-containing polymerisable acrylic composition.

EFFECT: material is a recoding medium for optical recording of information and is characterised by extremely high sensitivity.
