METHOD OF RECORDING INFORMATION ON POLYMERS Russian patent published in 2010 - IPC D06P5/20 G11B11/12 

FIELD: physics.

SUBSTANCE: described is a method of recording information on polymers through thermal action on a polymer, involving local thermal processing of a polymer at temperature below its glass transition point. The polymer used is a polymer object with a prolate form (film, fibre, tape, pipe, rod), made from plasticised or unplasticised, amorphous or amorphous-crystalline polymer, initially subjected to stretching in a adsorption-active medium from alcohols at temperature below glass transition point of the polymer, and then treated with a solution of non-thermochromic dye selected from a group comprising Rhodamine 6G, methyl green and methylene blue at temperature below glass transition point of the polymer and drying at temperature below glass transition point of the polymer.

EFFECT: invention simplifies the method of recording information on polymers.
