FIELD: chemistry.
SUBSTANCE: photopolymerisable composition contains a thermoplastic polymer, a solvent, a dimethacrylic compound and a photoinitiator. It differs by the fact that the thermoplastic polymer contains polyvinylbutyral; the solvent is hydroxyalkyl(meth)acrylate specified in a group of 2-hydroxyethylmethacrylate, 2-hydroxyethylacrylate, 2-hydroxypropylmethacrylate or 2-hydroxypropylacrylate; the dimethacrylic compound is phosphorus chlorine dimethacrylate; the photoinitiator is 2-hydroxy-2-methyl-1-phenyl-1-propanone in the following proportions, weight portions: polyvinylbutyral 1-10, hydroxyalkyl(meth)acrylate 10-60, phosphorus chlorine dimethacrylate 30-80, 2-hydroxy-2-methyl-1-phenyl-1-propanone 1-2.
EFFECT: producing uncoloured optically transparent polymer materials highly adhesive to silicate glass and low combustible.
