This invention relates to compositions of matter useful for marking and identification purposes comprising a continuous, pressure rupturable coating containing (1) a fluorescent material and (2) a water-insoluble, volatile, hydrocarbon solvent and a method of marking and identifying objects therewith.

Encapsulated fluorescent composition

This invention relates to compositions of matter useful for marking and identification purposes comprising a toluene, xylene or benzene solvent, a quinazolone fluorescent material and an alkyd resin and a method of marking and identifying objects therewith.

Composition for marking and identification purposes

Mono- and poly [dialkyl or dicycloalkylphosphonylmethyl] aromatic carbocyclic compounds are prepared by reacting an appropriately substituted secondary phosphine with formaldehyde, reacting the resultant dialkyl or dicyclohydroxymethylphosphine with an appropriately substituted halomethyl aromatic compound and oxidizing the resultant secondary phosphine.

Method for the preparation of mono- or poly [dialkyl or

In a solution that is free of bases and free of oxygen and which contains at least four molar proportions of the reactant tris(hydroxymethyl)phosphine for every three molar proportions of an aralkyl halide reactant, the following reaction produces tris(aralkyl)phosphine product:
