unavailability of traditional solvent paints

Talking to the tech support at Johnstone's the other week, they were saying something like this:

The VOC levels even in high VOC paints have been reduced. Current high VOC paints are in some ways more like water-based paints than "traditional" paints. The differences between high VOC and water-based still exist but have reduced considerably over the years. Water-based still tend not to yellow but do lose surface. High VOC still tend to yellow.

Bloody water based paint in our second toilet has yellowed very badly after around 2-1/2 years - despite there being no natural light at all in there and the lights only being on for less than half an hour a day. Even the door is shut virtually all the time.

I painted a bathroom door and the architrave in the same paint a few weeks apart, a few years ago. The door has yellowed a touch but the architrave has not ! Simon.

That's chemical yellowing then, not light. And I'm not talking about childish pranks either. Most likely it's toilet cleaner fumes.
