At first i was certain it is just a matter of boiling off all water, but  
now i know i was wrong because the effect starts at above 200C. Maybe it  
is some other component boiling off - some glycol?

Apart from acting as a etch resist the curing will also make the ink much  
more resistant to Acetone. But also air-dried ink will be much more  
resistant to acetone after several days then when fresh.

As far as i know we do not know the composition of MISPRO ink. Maybe  
someone could request a MSDS?
