ABSTRACT 1. An intumescent composition containing a cyclic nitrogen compound, a hydroxy-containing organo-phosphorus compound, an organo-phosphorus acid, and water, wherein: a) said cyclic nitrogen compound is Image wherein a, b, and c are integers selected from the group consisting of 1 and 2, a plus b plus c equal about 3 to 6, and X, X', and X" are independently selected from the group consisting of hydrogen and -CH3; b) said hydroxy-containing organo-phosphorus compound is selected from the group consisting of Image and Image and mixtures thereof, wherein d is an integer of from 0 to 2, e is an integer of from 0 to 2, f is an integer of from 1 to 3, and d plus e plus f equal 3; z is an integer of 0 to 1; x is an integer of 1 to 2, y is an integer of 1 to 2, and x plus y plus z equal 3- R1, R2, and R3 are selected from the group consisting of alkyl radicals containing from about 1 to about 6 carbon atoms and haloalkyl radicals containing from about 2 to about 6 carbon atoms, provided that when R3 is haloalkyl it contains at least 3 carbon atoms; R4 and R5 are selected from the group consisting of hydrogen, alkyl radicals, and haloalkyl radicals, wherein said radicals contain from about 1 to about 6 carbon atoms; and the total number of carbon atoms in the R1, R2, R3, R4, and R5 groups does not exceed about 14; and c) said acid is selected from the group consisting of Image , Image , Image , Image , Image , and mixtures thereof, wherein R6, R7, R and R9 are independently selected from the group consisting of hydrogen, alkyl of from about 1 to about 3 carbon atoms, haloalkyl of from about 1 to about 3 carbon atoms, and hydroxyalkyl of from 1 to about 3 carbon atoms, provided that the total number of carbon atoms in the R6, R7, R8, and R9 groups does not exceed about 5; wherein q is an integer of from 1 to 2, h and i are integers independently selected from the group consisting of 0, 1, and 2, and a plus h plus i equals 3; and wherein R10 and R11 are independently selec- ted from the group consisting of alkyl of from about 1 to about 6 carbon atoms, haloalkyl of from about 1 to about 6 carbon atoms and from 1 to about 3 halogen atoms, hydroxy-polyalkyleneoxy con- taining 2 to 6 carbon atoms and 2 to 6 oxygen atoms, alkoxy of from about 1 to about 6 carbon atoms, hydroxyalkoxy of from about 2 to about 6 carbon atoms, haloalkoxy of from about 2 to about 6 carbon atoms and from about 1 to about 3 halogen atoms, Image wherein R12 is selected from the group consisting of alkylene of from about 2 to about 6 carbon atoms, haloalkylene of from about 3 to about 6 carbon atoms and from about 1 to about 3 halogen atoms, polyalkyleneoxy containing 2 to 6 carbon atoms and 1 to 5 oxygen atoms, and hydroxyalkylene of from 3 to about 6 carbon atoms and 1 to 4 hydroxyls, and R13 and R14 are independently selected from the group consisting of hydrogen, hydroxyl, alkyl of from about 1 to about 6 carbon atoms, haloalkyl of from about 1 to about 6 carbon atoms and from about 1 to about 3 halogen atoms, hydroxy-polyalkyleneoxy containing about 2 to about 6 carbon atoms and 2 to 6 oxygen atoms, alkoxy of from about 1 to about 6 car- bon atoms, hydroxyalkoxy of from about 2 to about 6 carbon atoms, and haloalkoxy of from about 2 to about 6 carbon atoms and 1 to about 3 halogen atoms, provided that the total number of carbon atoms in the R10 and R11 groups does not exceed about 8.
