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??

@jili12 Thanks for the suggestion, I will look into that. My OP was also more along the lines of why an ages old formulation of the vinyl, which was clearly so effective ( thereby not requiring brushes or any other devices) is no longer utilized, or some additive similar to it. The current record producing companies seem to be unaware of this problem, yet in the past, a large company like RCA made it a priority!
I agree with Audioguy that switching from a felt mat to leather makes a big difference to the amount of static that the record accumulates. 
Back when I was developing the Redpoint Turntable with Peter, we had terrible static issues in the Winter. The solution for our designs may be relevant to you.

We grounded the bearing to the phono stage (any earth ground will do). You might not expect a bearing whose only electrical path from the platter surface to ground is the capacitive coupling between the bearing spindle and body (a distance on the order of .0001", separated by lubricant), but it does.

Obviously, there are two approaches to this problem: (1) keeping static from being generated, and (2) draining it to ground. Either one or both are viable solutions. I don’t want static production to dictate my record to platter interface, so I prefer option 2. Anyone who has experimented with the sonic effects of different mats (and their effect on energy transfer) will understand why.

I rebuild Fender Telecasters as a diversion, and I’ve found that some pickguard materials generate quite a bit static. Irrespective of whether I shield the pickup cavities, I’ll use some conductive foil under the pickguard to connect it to ground. Problem solved.

That's a good one. Mine's even threaded. Thanks!
One of our crazy designs (never made it to production) generated so much static, that, you could see sparks jumping from the platter to the turntable base. I kid you not. It didn't manifest until we hit the low-humidity Winter months, and needless to say, it came as quite a surprise ;-)
