Flame retardant treating agents according to the invention comprise a phosphorus-based compound represented by the following formula (4): 1 Flame retardant treated fibers can be obtained by immersion of polyester fiber woven fabrics and the like in a treatment solution containing the flame retardant treating agents and accomplishing heat treatment at a prescribed temperature. It is thereby possible to impart adequate flame retardance to polymer materials such as fibers and thermoplastic polymers even when used in small amounts, and provide flame retardant treating agents that contain no halogen compounds.
A flame retardant treating agent which comprises a phosphorus-based compound represented by the following formula (1) and/or its salt:
A flame retardant treated article comprising fiber having fixed therein a phosphorus-based compound represented by formula (1) and/or a salt of said phosphorus-based compound.
A flame retardant treated article comprising a thermoplastic polymer having fixed therein or containing a phosphorus-based compound represented by formula (1) and/or a salt of said phosphorus-based compound

1. Field of the Invention
The present invention relates to flame retardant treating agents, to a flame retardant treating process and to flame retardant treated articles composed of polymer materials such as fibers or thermoplastic polymers which have been flame retardant treated.
2. Related Background Art
The present invention will now be explained in greater detail by way of the following examples, which are not intended to be limitative on the invention.
To 40 g of the phosphorus-based compound represented by formula (3) above as component A there was added as a dispersing agent 5 g of an ethylene oxide 10 molar addition product of tristyrenated phenol, and then 53 g of water was added thereto while stirring. Next, 2 g of a 10 wt % aqueous solution of carboxymethyl cellulose was added as a dispersion stabilizer to obtain a flame retardant treating agent as a white dispersion.
A flame retardant treating agent was obtained as a white dispersion in the same manner as Example 1, except that the phosphorus-based compound represented by formula (4) was used as component A instead of the phosphorus-based compound represented by formula (3).
