Melamine resin contains melamine in a manner similar to table salt containing chlorine. While melamine is dangerous to ingest, melamine resin is not. Melamine is the chemical that has been contaminating pet-food lately. Melamine resin is the thermoplastic from which plastic-ware, counter-tops, etc are made.
If it is melamine, you can paint on it and will get the best results with spray paint. I would still prime it so that your top coat has something to adhere to and so that you don't get crackle. If the veneer really is plastic, then you can use the new Krylon paints for plastic to get good results.
