I just spent the weekend plus the last 2 days trying, and re-trying several diy pcb methods...toner transfer, using HP Presentation Paper, which I had used previously with pretty good success, the "wax" sheets from China sold on Ebay, mentioned in a few posts in this topic and others, and vinyl like you show here, for the first time.
With the laminator I am using, "GBC Personal Laminator" I found that toner was "mashed" and spread out, causing bleeding between tracks and pads. This was using standard FR4, 0.064 1 oz. copper pcb material. The "mashing" wasn't so bad with thinner 0.032 1/2 oz. copper material, as you would expect. I will say that using the freezing method of approx 20-30 minutes the toner transfered 100%...very good!
I retried the HP Presentation Paper I had used previously with moderate success using a water bath to remove the paper after laminating. The freezing method did not work well at all. Less than 50% of the toner transferred, using identical laminating techniques used before. So no go on the freezing.
I tried the "waxed" paper from shcfstore (ebay), in China. This took about 2 1/2 weeks to arrive...not too bad, and worked well with the freezing method of 15-30 minutes...about as well as the vinyl, without the mashing. So, this is a definite keeper.
I also tried, for the first time, the dry negative film, from Digole (ebay) in China. This is my first time using this particular film. I've used both positive and negative film in the past but this seemed a bit easier than any I have used before. It was very easy to separate the protective film and laminate to the board. I have had issues in the past with wrinkling and bubbling, but not with this stuff. It is also very easy to expose...just wait until the exposed film turns a dark blue/violet. Then develop in warm sodium carbonate solution (normal washing powder from grocery store) for 2-3 minutes. This makes the best boards I have done, 6 mil traces with 6-8 mil spacing.
