METHOD TO PRODUCE FILM IMAGE BASED ON COMPOSITION FOR CONDUCTIVE INK, MULTI-LAYER POLYCARBONATE PRODUCT WITH SUCH IMAGE AND METHOD FOR ITS PRODUCTION Russian patent published in 2017 - IPC B32B27/00 B82B3/00 C09D11/00 C08F2/46 B32B3/08 B32B37/14 

FIELD: technological processes.

SUBSTANCE: method to produce a film image based on composition for the conductive ink, including application of the composition and treatment thereof by UV radiation, so that the effects of UV radiation with the same spectrum of radiation on all UV LEDs correspond to the spectrum in which photographic initiators have the greatest sensitisation. The UV LEDs are fed with a series of current pulses which frequency ranges from 1 kHz to 10 MHz, and the composition comprises nanoparticles of metal complex compound obtained by reacting at least one metal or metal compound represented by the formula M_YZ, (1), where y = 1, 2, 3 … 10; M is a metal or a metal compound; Z is selected from a group consisting ammonium, oxygen, sulfur, halogen, cyano, carbonate, nitrate, sulfate, phosphate, acetylacetonate, alkoxide, carboxylate and derivatives thereof with at least one binder-based compound comprising a geminal-based polycarbonate derivative disubstituted dihydroxydiphenyl-cycloalkane represented by the formula

,

where R¹ and R² - hydrogen, halogen, chlorine or bromine, C₁-C₈-alkyl, C₅-C₆-cycloalkyl, C₆-C₁₀-aryl, preferably phenyl, and C₇-C₁₂aralkyl, preferably phenyl-C₁-C₄-alkyl, primarily benzyl, m-4, 5…7; R³ and R⁴ are C₁-C₆-alkyl; N is an integer greater than 20; X is geminal carbon, well as at least one supplement chosen from a group consisting of an oxidizer, a photoinitiator, a stabiliser, a solvent, a dispersant, a surface-active substance, a water, a thixotropic agent and a levelling agent. A multilayer polycarbonate article and a method for producing the multilayer polycarbonate article are also described.

EFFECT: film image based on the composition that does not form separating layers during lamination.
