FIELD: chemistry.
SUBSTANCE: present invention relates to a method for photochemical hardening thick-layered ethylene-unsaturated systems of light-emitting diode light sources. The invention describes a method of hardening ethylene-unsaturated polymerisable compounds to obtain coatings, external resinous layers or adhesives with cross-sectional thickness greater than approximately 0.25 mm, which involves addition of at least one acylphosphine oxide photoinitator to the said compounds and illumination of the obtained mixture with light from a light-emitting diode.
EFFECT: good surface hardening and good hardening in the mass without formation of surface wrinkles in case of thick cross sections.
