Etherified cellulose ether and liquid crystal as the ultimate substance with an interferential color effect for paint and varnish effects, especially on bodyworks of motor vehicles.

摘要

The invention relates to a polymer with backbone, IS photocrosslinkable AND LIQUID CRYSTAL AS EFFECTIVELY INTERFERENCE AND SUBSTANCE coloring FOR COLOR PAINTINGS IN WHICH THE MAIN GROUP ARE mesogenic PLACED at least about CHIRAL-NEMATICAMENTE. TO OBTAIN FOR POLYMER BASE CHEAP AND AVAILABLE, AND FURTHERMORE HAVE A HIGH CHEMICAL STABILITY ARE USED IN ACCORDANCE WITH THE INVENTION A (Eth) PULP etherified or a mixture of several (Eth) CELULOSAS etherified AS liquid crystal polymer HOME O backbone polymer with the following characteristics: - mOLAR MASS OF (ETHER) PULP 500 A 1000000, - UNITS anhydroglucose OF ETERCELULOSA EMPLEADA ARE etherified AN INTERMEDIATE mOLAR SUBSTITUTION 2 TO 7 UNITS propylene oxide or ethylene oxide (UNITS C {SUB, 3} H {SUB, 6} OOC {SUB, 2} H {SUB, 4} O), THE ETERCELULOSAS ARE etherified AN INTERMEDIATE mOLAR SUBSTITUTION 1, 5 A 3 WITH uNSATURATED HYDROCARBON RADICALS (SUB {C, H} {SUB R, 2R-1}.
