REFRACTORY DYE Russian patent published in 1995 - IPC

FIELD: painting, graphing in arts. SUBSTANCE: refractory dye has, %: refractory photostable pigment 35-40; magnesium oxide 0.5-1.0; aluminium hydroxide 3-5; pumice 2-5, and aqueous solution of aluminoboronphosphate or aluminochromephosphate binder with density 1,1-1,2 g/cm² - the rest. Powdery dye components (pigments and fillers) with dispersity 7-13 mcm were stirred, and aqueous solution of phosphate binder is added to the prepared dry mixture, and mixture is stirred thoroughly. Properties: film strength is 200-220 kg/m³, compression strength is 15 kgf/cm², adhesion - 4 marks (by lattice cut method), thermal stability is 200-1000 C, resistance to cold at (-15)-(+15) C is 25-75 cycles. EFFECT: enhanced quality of dye. 2 tbl
