Invisibility can be made permanent on an object, how about a corpse? Then raise from the dead?

[Rogar Stonebow]

So, how would this work? I always hear that corpses stop being creatures and become objects. If that is so, it can be targeted by permanency and have invisibility become permanent. Then, you cast Raise Dead on the corpse, or animate dead, or what ever.....

Does it remain invisible until dispelled?
Does it remain invisible till it makes an attack, thus becoming
visible, and then after a short time go back to being invisible?
Does it remain invisible till it makes an attack, and invisibility is
broken forever? (Wasting the money to make it permanent)
Does it become visible the moment the corpse returns to being a
creature?

What if you target a chair, and make the chair permanently invisible. Then cast animate object on the chair. Does the chair become a creature for a short period of time? (thus fall under the ruling from above?)

Permanency is always a waste of money, used on yourself (things change if you use on creatures that supposedly won't see much combat, or at least not with magic users, or on certain objects). Thousands and thousands of GPs, and the first village idiot who throws a Dispel Magic at you flushes everything down the toilet.
That said, Invisibility would go away when the creature attacks or when dispelled, whichever comes first.
The animated chair becomes a creature (Construct), so the same applies.
You can, though, make a normal chair invisible forever and make everyone stub their toes on it.

I'll answer this question. Yes. because it's no longer eligible for the permanency, and you reckon the spells duration from the time it was cast.

I'm not sure, but the creature will definitely not be permanently invisible. Nor will it remain invisible until dispelled.

Either it breaks the moment the corpse becomes a person, or as soon as they do something that would normally break invisibility. I'm leaning towards it breaking immediately.

Magic is weird and this is a game based on rules. Permanency and invisibility on an object is a specific ruling, as is with any other spell, if the target is no longer a legal target, the spell is gone. It's based on rules over an attempt at logic manipulation. You can't cast haste on a corpse because it is not a creature, if the creature with haste dies, the spell ends.
