Is this the solution to LP static issues?? Seems to be!

Last night i was listening to a superb original RCA white dog pressing of Lena Horne and Harry Belafonte ( if you can source this, i highly recommend it!) 
I noticed that all of my prior LP's were exhibiting considerable static attraction to my felt mat on my LP12. Not this one!!! How come, since the LP was played at the same time as the others, in the same system, the same room temperature etc.?? I noticed on the cover of the album the following large sticker: Miracle Surface, This record contains the revolutionary new antistatic ingredient, 317X, which helps keep the record dust free, helps prevent surface noise, helps insure faithful sound reproduction on Living Stereo.  

Whatever this additive is that was put on this album back in 1959 sure works well!! Anyone know what 317X is?? Why are we NOT using this stuff today??
